I have Buddy Club Coilovers (true coilover front and rear) with Swift springs.

My rear coilovers are completely bottomed out (screwed all the way into the fork) and damper is set to 4mm and there is still a 2 inch gap between my tire and quarter panel.

I can slam the front all the way to the ground no problem, but it seems like the shock body itself in the rear is to long. Or am I doing something wrong here?

Is it possible you have the wrong spring length? A picture is worth a thousand words...

What rear spring rate, are you running helper springs, ,what size tires are you running?

bcoffin23

This issue has been diagnosed. The rear spring rate was almost 1.5x that of the stock spring rate of these coilovers . Since the shock body wasn't shortened to accommodate the stiffer springs, the rear was stuck sitting to high.

Nice, glad you got it fixed. Figured the rate was too high for the spring length. How stiff are you running in true coilover config?

bcoffin23

Rear was at 650lb, stock should have been closer to 400lb.

So it was 50%+ above what those coilovers were designed for.

650lb in the rear. No helper springs.

Length was okay, spring rate was way to stiff for the shock body.

Length and rate are directly correlated, the stiffer the spring the shorter is has to be to give you the correct ride height.

Anyway, thats pretty stiff for coilover config. You must be running slicks. Good luck!

I am changing the springs to an 8k rate that is designed for the shock body.

I run RSRR from Federal tires. It is not a slick, but a pretty aggressive track tire. Once I start trailering the car to races/TTs......slicks it will be!

Or you use shock length to set the amount of travel and where the travel is. Then use preload combines with helper springs if required to set ride height.

I know what combo the faster cars on the track are using.

^yup thats how its done buddy. I am familiar myself also

Wasnt trying to imply thats how he should set his up, but obviously there was a spring issue.
