The STM Rear Drag Brake Kit for the 1990-1994 1G DSM allows you to ditch the weight of your heavy rotors and clear room to run smaller wheels and slicks. With a total weight of only 8.9 pounds per side with the scalloped rotor, we all know less rotating mass is the best way to free up power!

Vehicle Fitment:
1G DSM
1990-1994 Eclipse GST/GSX
1990-1994 Talon TSi
1990-1994 Laser RS

More Info:
The STM brake kits include Wilwood calipers and your choice of the standard rotor or the lightweight scalloped rotor, custom STM mounting brackets, black anodized rotor hats, Wilwood brake pads, STM brake lines and all mounting hardware.

This brake set-up is specifically designed for Drag Racing.
This is not intended for constant, on/off braking as in road-racing or autocross.
Will clear most 15" wheels.

For suggestions on wheel and tire combos, give us a call and we will make sure you are outfitted with the right set-up to meet your racing goals. We are direct with many wheel and tire companies and can ship them mounted & balanced to your door!

The scalloped rotor is 1.95 pounds lighter than the standard rotor and should only be used on drag cars.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
