So,you are the guy that spent 18k for a 08 Z at CarMax and you are drifting your car.
Don't have the funds to get it checked out but it seems to drive ok,I'd spring for
some new tires to start with.Especially if the sidewalls are damaged.The wheels
look like crap because of you hitting a curb?Options to fix are to get the wheels fixed/
refurbed(not cheap,what will you drive until you get the wheels back?) or buy some
OEM wheels.Check sources like ebay.Should get some at a decent price from guys that
put aftermarket wheels on.Be sure to buy REAR wheels due the staggered set up.
This may be difficult to find 2 rear.
You are right,lesson learned...don't buy a new car and commence to mess it up in
