Are the small "bump" progressive springs legal to use?

Eric,

I thought the rule stated "Only linear wound design springs permitted. No progressive, tapered or barrel
wound springs. All springs ends will be of closed design"

So no progressive springs....

The verbiage that you are referring to is for the main spring.

We looked at what to do with the bump stops and bump spring ( Advanced Suspensions ) and decided it didn't need addressed at that time.

I would assume that it will come up for discussion at the winter meetings.

So -- as long as you break the main spring into component parts and then call one the main, and the others something else, you have met the intent of the rule.  ??
