I found my front suspension too soft at track conditions. Can my Tein basics handle if I just swap in 500lbs front springs? Shocks have no stiffness adjustment. I have already RB sways and 949 endlinks.

I highly doubt it; my Super Streets couldn't handle a front 8mm/kg spring.

Having owned basics, I can promise you it will be a bad idea. The stock front rate is about 390, and the dampers have okay control of that. But 500 seems quite outside the design realm.


IMO, pull rear bar (or use stock), and fix the inherent spring rate ratio issue first, then try and upgrade to something else. If I was going to change rates on basics, it would be the rear spring, as the damper clearly cannot handle it.

Okay, I'll try stock rear bar. And if that doesn't feel right, I'll just have to get better coilovers. Cheers, guys!

No.

The Basics and the new Basis are street suspensions. No where near the low speed damping required for track or autocross. Basically, if you pull a helmet on, they're too soft. Tein Advance at minimum, or the new Street Flex which are great entry level track coilovers.
