Ultimate IRS Supra Coilovers - Suspension System for MKIV / SC300

The Grannas 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. These will bolt into your stock supra. 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
