Hi,

Will any performance springs fit with any shocks? Or are the springs designed to go with the stock shocks?

I have Ohlins shocks and the spring perch looks wider than the stock spring perch.

I need to bring the ride height up by buying different springs. So if I buy Eibach or HKS springs will they fit with these shocks?

 

The far majority of true coilovers use 2.5" diameter springs. These are common and easy to find, but be sure you know what spring rate you need first.
