I am looking to what folks may say as mess up a car. I just picked up a RS4 Sport 3 that I want to do up as a 68 Camaro. Being as I am old muscle car junkie I want to do this car up a more custom street muscle style. I have little experience with the car world as most of my stuff is crawlers and short course. I found some old school HPI Racing Super Dish wheels in both 20MM and 24MM and would really like to do a cheater slick on the tires around 26/28x12x15 style if anyone knows where I may find that area of tire for the back or a wider wheel for the back that would hold a tire that area that is still the old school dish style. As well I am looking to go a little backwards with this car wanted to get some opinions on what motor to run looking the 6000kv+ area possibly with the 26T/75T combo. I would really like to be able to pull the front tires up which I know this will be a little harder as the chassis isn't really designed to be that heavy muscle style. Any ideas or feedback would be great. Thank you.
