Dinan roll bars & rear axle

Peter_VIE · 08-19-2020, 11:37 AM

I recently had installed Dinan's roll bars front and rear. During my 2020 first track session I lost the outside axle boot of rear axle shaft (pic enclosed)

The boot was fully shredded, all grease went off.

Garage assumes, the new Dinan roll bar touches axle and boot in high load situation (I go with slicks), leading to a loss of the boot.

Did anyone have same issue?

You should be able to see on the sway bar where it was contacting the boot if it was. I had a similar thing happen to my F31 when I disconnected the rear sway bar and where the boot rubbed the bar there was rubber transfer and paint worn off of.

I'm kind of surprised your sway bar was contacting that boot since the end links are supposed to prevent that.
