About Mann Engineering

 

 

We strive to develop suspension, brake, and power packages that are complete with track proven results. We are one of the few companies that test our products before we make the decision to carry it. We do not just carry every brand out there but want to be one that carries nothing but the best for your Subaru.

In 2011, we became the exclusive distributor of Milltek Sport Exhaust systems for Subaru applications. We carry the full line of Subaru products from Milltek and assist in product development for specific US-Spec Subaru applications. Milltek Sport is the exhaust of choice for all the Type-25 US Editions.


Engineering and Development behind Mann Engineering

The engineering and development process is the foundation of a great product. At Mann Engineering we focus extensive amount of time during these initial stages to make sure that a product not only fits properly, but works how it is supposed to pertaining to a specific Subaru application. We pride ourselves in being consistent about this focus so that every product gets the same amount of attention on development and testing both on our shop and volunteered test vehicles.

In a normal new product development cycle, a properly developed product takes about 6-12 months or more depending on the complexity of the part.

- First 3-6 months: Engineering and development
- Next 1-4 months: Testing…..more testing…and more testing
- Final months: Production

Even after production is complete, we do not stop there. We constantly find ways to improve and make it even better. As new vehicles are released each year, we make sure to go through the same development cycle for the product so that specifications are confirmed as either the same or different than the previous and that any changes in the new vehicle are accounted for.

In many cases, a part from one Subaru application may fit another Subaru vehicle, however it does not necessarily mean it will work or perform correctly. Thus, products from Mann Engineering are not always the quickest to be released to the public for purchase because we take the proper steps to make sure the parts work together in the system correctly.  

Mann Engineering also carries products from other manufacturers. Over the years as we have grown, Mann Engineering has become a technical partner to many leading aftermarket companies that develop parts for Subarus. Companies like Advanced Clutch (ACT), AST Suspension, Brembo High Performance, and Samco Sport are just a few that we directly work with to develop parts for Subarus to make your car more enjoyable to drive. 

As a technical partner to some of the manufacturers, we assist in the development and testing process of their products as well. In many cases, we offer our shop vehicles as a medium to the engineering and development process for the part that is produced specific to Subaru applications. Feedback and testing results are sent back to the manufacturers so that they can make adjustments accordingly if necessary or confirm approval for final production run. 


History of Developments (Credentials)

Year Company Brand Part Number / Project Name Development
2006 Stillen Mintex Mintex Xtreme Motorsport Pads One of the initial testers of this product line. Provided report and feedback into the final product compound design.
2006 Swift Springs USA Swift Sport Springs 4F904 We proposed the initial design and sale of this particular application. Swift originally did not want to pursue this application and we took the risk of getting the springs developed, tested, and into production. We made it one of Swift’s best selling lowering spring kits.
2006 Swift Springs USA Swift Sport Springs 4F901V2 (Known as the current 4F901) The initial release of the spring was too low on US spec cars. We informed and requested that Swift to make an adjustment to the springs by changing the spring to increase the ride height for the 2004-2007 WRX Sedan.
2006 Swift Springs USA Swift Sport Springs 4F903V2 (Known as the current 4F903) The initial release of the spring was too low on US spec cars. We informed and requested that Swift to make an adjustment to the springs by changing the spring to increase the ride height for the 2004-2007 WRX Wagon.
2008 Stillen AP Racing AP6300 We did the initial test fitment of the brake kit on the 2008STI to check if any adjustments that are needed. The original test fitment was tested with the 3D printed brackets. Once the necessary clearances were checked, the kit went into production and is as you see it today.
2008 Stillen AP Racing AP6350 We did the initial test fitment of the brake kit on the 2008STI to check if any adjustments that are needed. The original test fitment was tested with the 3D printed brackets. Once the necessary clearances were checked, the kit went into production and is as you see it today. The early production brackets made were made out of billet steel while asked for future kits to use a bracket made out of aluminum to save weight. We also tested the early aluminum version bell hat for this kit and final production kits used a cast iron hat for those that use the parking brake aggressively or for normal street use as the aluminum hats would distort when hot.
2008 Stillen AP Racing AP Strap Discs Mann Engineering was the first to test these rotors in the US. The discs were originally brought over as a new rotor concept that would have the benefits of two different kinds of 2-piece rotors. They had the benefits of a solid two piece rotor and a floating rotor. 
2008 Stillen DBA DBA Double Drill Rotors Contacted Stillen Brake Division Manager to have DBA to double drill rotors for dual PCDs for STI rotors for 2004-2007 and 2008-2015 STI models.
2008 Swift Springs USA Swift Sport Springs 4F902R We proposed producing a lowering spring line that would have more spring rate than the Sport Springs, which led to the Spec-R Lineup with Swift. We also proposed the original color to be metallic blue and assisted development for the Subaru applications.
2008 Swift Springs USA Swift Sport Springs 4F907 We tested the original prototype set out and made a revision to make it to what it is today. The initial production spring set was over sprung in the rear which caused the car to produce an extra undesired “hop." After the initial test, we proposed that a revision be made and current set is the finalized set.
2008 Swift Springs USA Swift Sport Springs 4F906 Tested and made sure that they worked equally well for both the sedan and wagon platform. After confirming ride height and ride comfort, the released set was approved by us.
2009 Speedline Corse Speedline Corse 18x8.5 Turini for STI with 5x114.3 The original wheel was an ET55 offset and change was requested by Mann Engineering to make it an ET52 offset to be able to not only clear the OE Brembo calipers but also other aftermarket big brake systems. Currently all 18x8.5 Turini Wheels for the STI are now ET52.
2009 Stillen AP Racing AP3100 Bracket Revision 2 for STIs At the time, we informed Stillen to make revisions so that kits would work on WRX and STI models. The 2005-2007 STI had an extra piece of iron cast on the steering knuckle such that it would not allow original Stillen made aluminum brake bracket design to fit. AP Racing also made a bracket change as well to their Classic Formula kit to account for the extra casting at the same time Stillen made their revision.
2009 Swift Springs USA Swift Sport Springs 4F908 Following the popularity of the 4F904, we proposed the initial design and sale for the 2009-2013 Foresters. Final production of the springs were approved by us and is what is currently available today. 
2009 Swift Springs USA Swift Sport Springs 4F909 Tested and made sure that they worked equally well for both the sedan and wagon platform. After confirming ride height and ride comfort, the released set was approved by us.
2010 Stillen Mintex Mintex F3R During the testing of the Xtreme Motorsport compound on the track, we found that it did not have enough temperature capacity. A new pad formulation was developed utilizing the Xtreme compound as the starting platform and the F3R was born to maintain the same great feel of the Xtreme Motorsport compound but with higher temperature capabilities for track use only.
2010 Stillen AP Racing AP CP7040 Competition Gray Caliper We proposed removing the rectangular embossed logo location to be completely flush during the initial caliper revision stage. We tested the first batch of calipers and found the iconic yellow AP Racing logo paint did not stick very well onto the caliper. Later it was decided with Stillen at the time to not have the yellow logo anymore as a better solution was agreed upon. This version was also the first “classic” caliper that utilized the reverse torx bolt to improve the caliper stiffness and consistency.
2010 Stillen Goodridge Goodridge STI Brake Line Development At the time, we proposed to Stillen brake division manager to make STI brake lines for 2008-2014 STIs. Proposal was then implemented to allow this product line to be available to Subaru STI specific applications as Goodridge did not have the lines and many were using the incorrect lines for the application.
2011 Milltek Sport  Milltek Sport  Titanium Tips for 2011-2014 STI We had Milltek produce this trim tip style to give the STI a very unique look as Titanium was being used in other applications, with the burnt look at the time but never a brushed finished look.
2011 Milltek Sport  Milltek Sport  Various Took the entire Milltek Subaru catalog and matched every system possible to create various Milltek Exhaust Systems for GD, GG, SG cars that normally Milltek would have never offered.
2011 Whiteline Whiteline BSF43Z The SH Forester Non-Turbo Front Swaybar was needed as the original bar specified did not fit and requested that Whiteline produce a different bar that is dedicated for the Non-Turbo applications.
2012 AST Suspension AST Suspension ACS-S1301S / MEACS-SUB1301 Assisted in the development and testing of the first true dedicated coilover application for the SG Foresters that has everything that was Forester specific.
2012 AST Suspension AST Suspension ACS-S1302S / MEACS-SUB1302 Assisted in the development and testing of the first true dedicated coilover application for the SH Foresters that has everything that was Forester specific.
2012 AST Suspension AST Suspension ACS-S1401S / MEACS-SUB1401 Designed and developed the drawings for the kit (BRZ). Shock setup and lengths were confirmed and specified by us.
2012 AST Suspension AST Suspension ACU-S1401S /MEACU-SUB1401 Designed in parallel with the 4150 BRZ Kit or ACS-S1401S
2012 Stillen AP Racing AP6100 We told Stillen that this kit was the same as the AP6300 but needed to run a leading caliper for the BRZ and FR-S. After Stillen confirmed our finds with a car, the kit was quickly released into production.
2013 ACT ACT ACT Pull-Type Clutch Kits We were one of the first to test the ACT Monoloc on a vehicle and assisted with feedback on the patent.
2013 AST Suspension AST Suspension RAC-S1401S Designed in parallel with the 4150 BRZ Kit or ACS-S1401S
2013 Milltek Sport  Milltek Sport  BRZ Automatic Cat-Delete Pipe The original pipe was designed on a manual car and we persuaded Milltek to design an automatic pipe as there are quite a lot of automatic Subaru BRZ and Scion FR-S vehicles sold. An agreement was made on the redesigned pipe to make it fit both manual and automatic cars.
2013 Speedline Corse Speedline Corse 17x8 Turini for BRZ We designed this wheel based off the motorsport wheel and made it for the street. We wanted to increase the tire width without increasing the weight. The wheel was designed such that it can run square or staggered with the 17x7 Turini offering. This wheel was created as many wish to go wider without having to go larger in diameter and was a specific offering for the BRZ. The Brembo 4-Piston GT System was designed to fit under this wheel. We proposed having the brake system made so that way it leaves options for customers to select more common tire sizes and possible wheel options.
2013 Speedline Corse Speedline Corse 17x7 Turini for BRZ This wheel was designed to run staggered with the 17x8 Turini or square. The goal of this wheel was to be stronger and lighter than the OE wheel.
2014 ACT ACT ACT Clutch Kit - BRZ / FRS Development We tested the Streetlite kit for the BRZ/FR-S and suggested redesigning the flywheel for noise as gear rattle was present and not pleasant for a street car. We also noticed that the clutch kit produced a significant amount chatter and the feedback allowed ACT to alter their production process and found the newly produced discs to have little to no chatter at all.
2014 AST Suspension AST Suspension TMA-S01-C1-20F / Raised Top Mount Proposed and designed the top mount to increase travel as the BRZs lack much suspension travel in the front.  We specified the design parameters.
2014 AST Suspension AST Suspension TMA-S08-B1-20F / Raised Top Mount Followed the same principle as the TMA-S01-C1-20F and applied it to all the newer Subaru applications.
2014 Milltek Sport  Milltek Sport  BRZ Brushed Titanium Tips This tip was designed to follow the similar style with that of the 2011-2014 STI Sedan systems with the brushed look, but to have the aggressive angle with that of the stainless steel tip.
2014 Milltek Sport  Milltek Sport  BRZ Burnt Titanium Tips We wanted to have a unique titanium look that very few exhaust companies have and we requested that Milltek has never done before and to give the BRZ/FR-S a very unique look. We proposed the burnt titanium tip idea as they had an already great brushed look but wanted to add some flare to it with the burnt portion of the tip.
2014 Race Technologies Brembo  332x32mm 4-Piston Front GT Brake System for the Subaru BRZ/Scion FR-S This brake system was pressed forward by us and we provided the necessary wheel drawings for Brembo in order to have this kit made as customers wanted to stay with a 17inch wheel option and not be forced to go with 18-inches. The brake system was designed to fit under our 17x8 Turini that we designed for the BRZ/FRS such that we can provide a brake and wheel package to our customers. Original proposal was to use the OE STI Brembo caliper but having gone back and forth, found that the caliper did not have the correct piston sizing to work with the BRZ master cylinder and would have produced even poorer braking results.
2014 Race Technologies Brembo  332x32mm 4-Piston Front Race Brake System for the Subaru BRZ/Scion FR-S This brake system stemmed from the 332x32mm Brembo GT Brake system for the BRZ and used a dedicated track caliper with a quick release mechanism to quickly change out pads at the track.
2014 Samco Sport Samco Hose Development - All Subaru models Being a long time supporter of Samcos hoses, we are recognized as a Subaru authority and are asked to assist in the design and development of hose packages and to make sure the hose kits will work on US-Spec Subarus. In addition, we have become a distributor for Samco Sport hoses for Subaru models in the US.
2015 Zircotec Zircotec Zircotec Coated Exhaust Tips (Tailpipes) First company in the United States to offer Zircotec coated exhaust tips for the new Subaru Milltek Sport Exhaust line-up.
2014-2015 AST Suspension AST Suspension ACU-S6211S Designed for the 2015 as WRX and STI, Proposed the development and setup of vehicle.
