I design setups for these cars. Select the right spring rates and then valving and then find dampers that I can have valved the way I want and then put them on the car. I let the bigger companies make the dampers, I just tell them how I want it inside and what I want it to do.
Good enough for the car, I mean that the Supra can handle very well, it has a good suspension design and its only real downfall is its weight, but even that isn't too bad. There's tons of room for good sized wheels and tires, the balance could be a little better front to rear, but overall it is a very good platform to start with.
So when I started messing with these cars, I didn't want to just throw some crappy damper with poorly selected spring rates onto the car and slam it, I wanted to put something together that would make the car work like it should. And this is one of the easiest cars to convert the mounting to work with any damper with 1/2" bearings on the end. So there are tons of possibilities and many different awesome dampers that can be used on this car.
