Shakedown of the Cuda

I made my first pass this past Saturday with the new car. I took it easy launching and at the top end to see what I had.
I found a few things.
Passenger wheel wobbles when braking. The car has a rack in it. The rack itself needs replaced.
Also Too much RPMs at the stripe. Previous owner told me he replaced the back tires. 30x10.5s. I lifted at 7000 rpm. I found out later that he had 32's on it before. It has 456's out back. I'm thinking about going back to 32's.
