Latest GRM Issue CMC Story - Upper PHR Brace Modification Query

If that is legal... I am adding a giant...heavy ass bar to the rear for weight purposes and call it a saftey thing.

I would never run that chain. It does limit droop. It also will limit body roll if the springs allow the body to roll that far. That would be like increasing the rear roll rate significantly instantaneously.

Unsprung weight is a bad thing.

7.33.4 Springs of any rate, OD, ID and free length may be used. Springs must install in the OEM stock unmodified location using the original system of attachment unless noted elsewhere in these rules.

So it's CMC legal to weld/bolt a plate on the top for an upper spring perch? You can't see from the pics if they have or not, but I know I had to on my AI car to run 2.5" springs. Also, so it would be CMC legal to weld perchs for the front to use smaller springs?

[GlennCMC70]

I didn't say that.

Apparently after TWS, there is a new CMC ruleset that says anyone can do anything as long as it is justified in thier own mind.

I would rather limit the travel than lose the spring. Besides, if your body is rolling over that far, you've got way bigger problems than worrying about rear roll rates (lilke what front suspension component has left your car).

Remember, illegal parts are allowed as long as they are installled improperly.
