Couple of Extended CRT.5 questions

[marcus]

I'm going with the extended chassis set for my CRT.5 project and have a couple of questions.

I've seen some of the other .5's on here but wanted to see if some of you guys had specific comments.......

Which bodyshell is best suited to the extended Chassis? Or will the stock body work ok with new holes?

Which is the accepted wheel/tire combo for this setup? Track is a fast smooth type with loose surface dust/sand...

Thanks for any pointers
