Just google them. Custom wound coil springs would be your best bet for stiffness and ride height. Coupled with some bilstein struts you'll be golden. If you want height and ride adjustability, coilovers are the only option. And in that case, Stance coilovers are your best option.

Whats wrong with tokicos? They give the car a crazy raked stance and the spring rates are way too low. The rake is kinda bad but they are the best thing in my opinion compared to coilovers. But they were so soft i hated them i had alot of squat and body roll with them vs what i have with my z3r gray z or my st front and ss cut rear on the red z.

Without going coilovers, the best off the shelf combo is probably Konis paired with a second hand set of Z3R or ST springs. Bilsteins would go well with either spring, and be more budget friendly.

Coilovers or custom springs would open up a world of options in spring rates and lowering though. I've got a set of SS springs and Konis that should be making their way onto my 86T. I don't care about lowering it really blasphemy, I knowbut it will handle way better than the worn out stock springs and crappy Monroes the PO swapped in. No idea, I went directly to coilovers because I wanted the height adjustability. Don't mean to threadjack or anything, but here is a quote I received from coilsprings.

If you choose to stay with stock springs the spring set from a Shiro Edition are stiffest springs you can get without going after market.

Some common after market spring rates are shown below. The idea of a progressive variable rate spring is to allow a smooth ride when driving normally, and improved body control when cornering hard.

Variable rate springs are easy to spot because the springs are not symmetrical.

Typically, one end of the spring is wound tighter than the other end with the more tightly wound end being the softer part of the spring. As the spring is compressed, the soft coils on the tightly wound side will collapse, coming into contact with each other.
