I started this kit a few months ago and put it on the back burner to finish a funny car. I own a 1:1 '04 GTO so if you need any reference pics, let me know. Here is what I have done so far...
I cut the 4 tabs off the wheels and added a styrene ring so the rims would fit some Bridgestone Expedia tires, and shortened the front struts to lower the car.
Your paint job looks great.
