bump stops/springs

chevelle clip currently run a 600 rf spring....thinking of going to maybe a 400 rf spring with a 1200 spring stop.....my questions are...

how much gap to leave at ride height between bump spring and bottom of shock shaft....

and should I go to the 400 or can/should I leave in the 600 and add the bump spring when track goes slick....

when running this, leave lr bite alone, add, subtract?

seen many top runners in our area on some sort of bump setup on rf..thanx for any input.

Not really easy to explain give me a call some time and I can hook you up with what you need and a good baseline. 573-330-8462

If running a RF bump it does help to reduce static cross. Your cross goes way up when you get on the bump
