Ultimate IRS Supra Coilovers - Suspension System for MKIV / SC300

Ultimate IRS coilover suspension setup includes double adjustable shocks, along with adjustable lower rear control arms. This allows you to not only fine tune the shocks, but also adjust your camber for maximum contact patch when the car is squatting on launches. The setup does not use a bolt-in body shock but rather a more mainstream and readily available dual eyelet shock for easy servicing and replacement in the case of a failure at the track.

Current Shock Options:

• Strange double adjustable coilovers with 350 lb springs rear / 550 lb springs front
• "PRS" Penske based strut which are custom valved for the Supra chassis and they are double adjustable (no canister) w/ 350 lb strange springs  rear / 550 lb springs front
• "PRS" Penske based strut which are custom valved for the Supra chassis and they are double adjustable with fine tuning canister adjustment (same setup I run on my 6-speed car) w/ 350 lb strange springs  rear / 550 lb springs front

These will bolt into your stock supra or SC300.

The Ultimate subframe is NOT required to run this setup! 

The kit is both front AND rear shocks.

The mounts include mounting provisions for travel sensors so you can fine tune your suspension on launches, going around/down the track, as well as on hard cornering for the road course guys!

This full 4130 chromoly construction control arm and upper hat mount setup allows for use of a double adjustable shock, which allows you to not only set compression, but also rebound, which is really important in setting up an IRS suspension. Rebound allows you to control how quickly the car comes back up from the squatting position, this allows you to keep the car planted rather than bouncing up and down when the car unloads, such as in a 6-speed car during shifts!
