Coilover spring rates

[Adz2332]

Hey all

im looking at a set of HSD monopro coliovers for my r33 gtst TRACK ONLY car. Used 90% for track days hill climbs etc, 10% drift... if that!

What spring rates would you recommend?

Anyone used the HSD at the track?

thanks

I've never used HSD on the track before but I'd imagine something similar to 8 kg/mm in the front and 7 kg/mm in the back would be a good place to start.

Depends on the surfaces.  Smooth tracks go towards 12/10 and rougher tracks as Hank suggests.

Way too soft, I'm running 10/7 on MCA X-R and that's too soft for my liking.

With some basic aero I would go even 12/9 and run softer ARB to promote roll for lateral grip.

Why do you want roll if you have aero?  Roll stops the front splitter working properly.
