The Racer X Fabrication rear upper control arms for the 2013+ Scion FR-S / Subaru BRZ / Toyota GT86 are the best option for adjusting camber on the rear of your vehicle. The pivot point allows for minimal impact on toe during camber adjustment. The tubular design allows for a weight savings of 4 lbs per control arm (8 lbs of total weight reduction), by far one of the largest weight savings for suspension components. The upper control arms retain the OEM wire harness mounting bracket and use...

The Racer X Fabrication center feed intake manifold for the 1991-1995 Toyota MR2 / Celica is a perfect addition to any build!! Increases in horsepower and torque will vary to each build but average gains are 40 whp and 30 ft/lbs torque. The center feed intake manifold is perfect for the side mount intercooler and allows for almost OEM packaging. Construction The Racer X Fabrication center feed intake manifold's gains can be attributed to our plenum that is designed to eliminate the flow issues...

The Racer X Fabrication intake manifold for the 2012+ Chevy Sonic and 2011-2016 Chevy Cruze was designed to increase power in the mid to high RPM range. The manifold starts with a CNC machined intake flange that features common sized o-ring gaskets for a perfect seal to the cylinder head. The flange is angled for the correct fuel injector location and matches the OEM placement. We also added a NPT port to allow for a simple PCV fix over the OEM intake manifold. This allows use of our optional...

The Racer X Fabrication rear upper control arms for the 2008+ Subaru WRX / STI are the best option for adjusting camber on the rear of your vehicle. The pivot point allows for minimal impact on toe during camber adjustment. The tubular design allows for a weight savings of 4 lbs per control arm (8 lbs of total weight reduction), by far one of the largest weight savings for suspension components. The upper control arms retain the OEM wire harness mounting bracket and use urethane bushings with...

The Racer X Fabrication 4130 chromoly front lower control arms for the 2015+ Subaru WRX / STI are one of the limited options available for adjusting camber and caster. The durable chromoly steel construction allows for simple, on vehicle, adjustment using adjustable threaded adapters and chromoly rod ends. The tubular design provides a 1 lb weight savings per side (2 lbs total weight saving) over the aluminum OEM version of the control arm. The Racer X front lower control arms retain the OEM...

The Racer X Fabrication front lower control arms for the 2013+ Scion FR-S / Subaru BRZ / Toyota GT86 were designed to reduce weight and increase rigidity. The OEM front lower control arms have been known to bend and flex under load. The Racer X control arms eliminate this by using light weight 4130 Chromoly tubing and chromoly rod ends. The control arms were designed in CAD from the OEM model to match and follow the small angle that is located at the rear of the control arm. The arms allow for...

The Racer X Fabrication side feed intake manifold for the 1991-1995 Toyota MR2 / Celica is a perfect addition to any build!! Increases in horsepower and torque will vary with each build but average gains are 40 whp and 30 ft/lbs torque. The side feed intake manifold is perfect for air to water intercooler setups or trunk mount intercoolers, but can also be used with the side mount intercooler. Construction The Racer X Fabrication side feed intake manifold's gains can be attributed to a...

The Racer X Fabrication cold air intake box for the 2012+ Chevy Sonic 1.4L is designed to improve performance through the full RPM range. We started with aluminum sheet that is CNC cut, and bent to form the air box. The panels are then TIG welded along with our 4.5” velocity stack that is specifically designed for the Sonic 1.4L engine. The velocity stack features a full bell radius, and tapers down to the OEM MAF diameter for the correct airflow. The velocity stack and taper increase airmass...

The Racer X Fabrication 4130 chromoly front lower control arms for the 2008-2014 Subaru WRX / STI are one of the limited options available for adjusting camber and caster. The durable chromoly steel construction allows for simple, on vehicle, adjustment using adjustable threaded adapters and chromoly rod ends. The tubular design provides a 1 lb weight savings per side (2 lbs total weight saving) over the aluminum OEM version of the control arm. The Racer X front lower control arms retain the...

Why it works The Racer X Fabrication Catch can for the 2013+ Scion FR-S / Subaru BRZ / Toyota GT86 was designed to reduce oil in the air stream when exiting the PCV and crankcase. The catch can / air oil separator works by intercepting the air / oil from the PCV or crankcase, and through a series of filters and baffles, keeps the oil in the catch can and allows the air to flow through. As the air and oil droplets enter the catch can they first pass through a micron stainless steel sintered...

The Racer X Fabrication intake manifold for the 2013+ Scion FR-S / Subaru BRZ / Toyota GT86 is designed to increase horsepower and torque. The manifold increases power from the mid to high RPM range with gains as high as 11 whp and 12 ft/lbs of torque. This was achieved using a stock engine with no other modifications besides a drop in panel filter and the use of the stage 1 tuning from an open flash tablet. This manifold is the culmination of 6 previous prototypes, multiple dyno pulls and...

The Racer X Fabrication straight runner intake manifold for the 1991-1995 Toyota MR2 is a perfect addition to any build!! Increases in horsepower and torque will vary to each build but average gains are 40 whp and 30 ft/lbs torque. This intake manifold is housed in the trunk of the MR2 and has the best efficiency due to the runners being almost perfectly straight. The design also allows the plenum to be isolated from the HOT engine bay and reduces intake temperatures. The straight runner...

Why it works The Racer X Fabrication Catch can for the 2012+ Chevy Sonic was designed to reduce oil in the air stream when exiting the PCV and crankcase. The catch can / air oil separator works by intercepting the air / oil from the PCV or crankcase, and through a series of filters and baffles, keeps the oil in the catch can and allows the air to flow through. As the air and oil droplets enter the catch can they first pass through a micron stainless steel sintered filter to begin the...

The Racer X Fabrication master cylinder brace for the 2013+ Scion FR-S / Subaru BRZ eliminates deflection from the master cylinder during braking. The master cylinder can deflect as much as 1/16 of an inch, with the Racer X Fabrication master cylinder brace this eliminates deflection. The cylinder brace provides better feedback during braking and lets you concentrate on driving. The master cylinder brace is CNC machined from 6061-T6 aluminum and bolts to the driver side strut tower. What's...

The Racer X Fabrication light weight alternator bracket for the 91-95 Toyota MR2 is a great start to reducing weight and saving space. The OEM alternator bracket takes up a large amount of space on the 3-SGTE engine and weighs a little over 11 lbs. The Racer X light weight alternator bracket kit is CNC machined from 6061-T6 Aluminum and weighs just under 2 lbs fully assembled. The tensioner is made from zinc plated hex steel and uses rod ends to allow adjustment over the full range of worn or...

The Racer X Fabrication engine rotation delete kit for the 2013+ Chevy Sonic was made to drastically reduce the rotation of the engine under load. It’s no secret, the Chevy Sonic was sold with only 3 engine mounts this leads to a significant amount of engine rotation which is great for daily driving, but absolutely horrible for performance. We decided an engine brace was the best way to eliminate the engine movement under load, this allows you to keep the spongy OEM mounts while still...
