Ryan,
I agree with some of the others... Backdraft would be the way to go.
I have taken a very hard and serious look at the Backdraft and the cars are well built. The customer support organization is also very good which to me is very important.
They have a number of local distributors here in the US... One here in the DFW area Hi-Per Rods. Robert is great and can help you out!

I do like the BMW suspension, but it depends what you want to do. The M3 package I think would make it handle awesome, the one I drove had the standard package. The nice thing is parts... you need a part, alignment, etc. The BMW dealer is a lot easier to get a hold of
To bad you did not make it to Austin, TX last week with 75 to 80 cars you would have had a few to look over (I sure had a blast)
Good luck in your quest for the ultimate ride
