Not had any shuddering at all in the brakes - did have a slightly out of balance right front that I could feel on the straight but other than that, all good.
Pulled the Toyos off and put the street sneakers & pads back in place.
Front end may have just a touch too much camber - inner shoulder is getting warn a bit more than across the tread.
This set of tires has 5 sessions running on the right side of the car and 10 on the left. Bet you can guess which one was on the left side on a clockwise track. Shoulder's a tad on the thin side.
Both back tires look good - wear is quite even. Might be a very slight too much camber or more than likely toe, which would explain some of the after apex twitchiness.
Regardless, all good info for tuning. I'll be taking it in to put it up on a lift and play with settings here soon.
Anyone else have GC camber plates? Do yours knock and rattle over bumps and such?
