I am going to use my old turbines with knackered tires to drift with, so that wont matter. We have a lot of old airfields here in the UK and they just cone out a course in like a figure of eight and other shapes and then one car at a time take turns to drift round it. I will get some pictures taken and post them up here once we have been...
If you are talking about my wheels, they are Azev 'A's 7 1/2x17, I got them imported from Germany, took about 16 weeks, but they look superb!
Check them out here...
