My mate uses clio cup slicks on his Evo because his wheels are 8x17, I'll ask him on Monday night if I remember.
Might be a bit hard for the team your speaking to to get 16 wheels from R-Sport as I think thats the amount the car comes with :lol:
I wouldn't worry about using them on track and they cope well on damp tracks too so it doesn't need to be bone dry, so long as theres heat in them and no standing water
Your going down the best route IMO as track days kill road tyres. I have track wheels with R888's...you know how much they cost etc and I've kept an Excell document of dates and miles the have been on the car. Currently 3800 and I'm hoping to change them just after summer.
No 'sports' road tyre would do that and you'd spend a hell of a lot more doing that mileage if it wasn't on a 'semi slick'.
