ahhahah, I'll have to remember that trick, thanks!
I have big C-clamp so I can do everything in pits. That was back in early days. Now I just have 2nd set of wheels.
Was really handy last weekend at my 1st time out at Wild Horse Pass. After 2-practice sessions and 1st race, I needed new tyres for 2 more races after lunch due to rough surface. These Alpha 13-SP tyres usually lasts me an entire season of +40 days @ track too!
