Does anyone use KGM springs for HDPE/autocross? I autocross once a month (on street tires) and do track events a few times a year(on same street tires), would these springs be an upgrade, or another "I should have left it stock" thing?

 

There are many BC ppl run them on Auto-X. I think you can ask them about it.

 

Have you heard of anyone bottoming out on the track with these? What do they do to the balance?

 

Very nice street and auto-x springs I must say. It's great to go with either KYB AGX or Bilstein shocks(struts).

I'd rather run shocks & springs and stick in C/SS somehow, LOL.
