Higher Spring rates on Billy Sports? Something else?

[dinanm3atl]

So from searching and reading it seems you don't want to go past ~350-400lb in the front and ~500-600lb in the rear. I have some coilovers coming and would like to potentially run something a little higher than this.

The car is a daily but will see the track and I feel that some slightly higher rates will work much better with some sway bars.

So the question is with the threaded adapters and standard length shocks how high a rate can I go with on the Billie sports? 300lb front and 550lb rear are coming. I was thinking maybe Koni would be a better option.

Only other option is shortening the housings and then running the shortened Konis? I just don't need/want to be that low and if the shortened konis can handle much higher rates it would make sense the longer ones can?

Thanks!

Anyone?

Get them valved properly for your car, it's not that expensive.

Getting Bilsteins revalved will be cheaper than buying Konis new.

Turner did that for me with my H&R Race on the E36 M3. Guess Bilstein could do it direct. I think it was 60ish a shock and 100ish for a strut assembly. Cheaper since E30 is basically just 4 shocks.


Any other options to get it done?



Also GC uses pretty much 100% 2.5ID springs correct?
