- Is a smaller wheel diameter preferred? Presumably larger sidewall height is preferred... Larger sidewall is needed. This means smaller wheel size will have to happen to keep rolling radius samish
- Is a stock 16 rear wheel (9x16 I think) wide enough, or do I need more? I use 16" stockers mate. Do a good job and some people use RX7 Wheels on Supes too. They are wide enough. I don't slip any more but did badly on normal road tyres
- What are the preferred drag tyre's sizes? I saw both Justin and the Envy car had very large diameter MT's on and seemed to have fantastic grip at Jap Show. 255 x 16" x 50 Mickey Thompson ET Streets. Road and MOT legal and grip brilliantly. YOU NEED TO WARM THEM UP though for at least a 5, 6 second burnout or they won't be as good.
- Do arches generally need rolling to fit decent size tyre's? Don't think so
- Supplier's? Websters as Jamie says. That is where I buy my tyres from. This is Ian behind my car dringking tea!http://website.lineone.net/~jmoat/Jap_Show_06/thumbs_d/md_IMG_9102a_jpg.html
Hope this helps mate.
