Opinions/experience: Best spring to pair with Bilstein sports for AutoX/Track days?

[EricusMaximus]

I just picked up a brand new Bilstein B12 suspension kit (re-valved Billie sports & Eibach pro-kit springs). It was a local cash deal for less than half the cost of new shocks/struts alone so I couldn't pass it up.. However my understanding is that the Eibach pro-kit is not a very stiff spring and I would be better off using the Billie's with a set of H&R race springs for autocross and road racing.

Right now the 3 options I'm considering are:

A) Turf the Eibachs and buy H&R race springs
B) Ground Control coilover conversion kit
C) Run the Eibachs


Any advice?

As with most things track-related it's really a function of your budget.

That said, if you're a novice on the track go with the H&R Race springs. If you have some days under your belt already, you may benefit from a CG setup and the added chassis tuning ability it offers.
