The pre set up is awesome. Especially HKS already has it pre set for you. The ride is a little bit stiffer and with the factory sensors the car doesn’t go to limp mode. However one thing I notice is the rear sensor. If you guys are going to lower your GR Supra please be careful for the rear sensor. That piece is plastic and it can break easy. Make sure you disconnect the rear before you remove the shock and the spring in the rear “left” side. Luckily mines only got loose and it did not break. Most videos on YouTube out there will show you how to install them, but they do not mention the rear sensor. So remember that theirs a rear sensor and it is fragile. As you see in the pictures the plastics sensor should be upright near the spring. Otherwise if not the car will go into “limp mode”. Overall I recommend over the lowering springs because with this you can still adjust the ride height and plus you can never go wrong with HKS.
