I used the Schroth QuickFit pro for one short season and is in new like condition.
It has the Anti-submarining function specifically designed for the S550 and that belt is included.
The belt has never been stressed due to a collision or sudden stop and only used on the track.
Drivers side only...
My 2020 GT350 Chassis L1483 dropped #8 valve the other day.
No oil consumption, no ticking, no bangs, felt it bog down and coasted to the side of the road and that was that.
Got it pushed into a trailer and took it to the dealer.
New long block to be delivered tomorrow.
Only 1900 miles.
I've changed my 2020 Gt350 to BMR handling springs giving me higher rates front & rear.
Will the stiffer springs affect the swing/spoiler downforce in the rear and in turn the front aero?
