Dont forget to reroute or cable tie out of the way the handbrake cable or the wider wheels will rub it. Definitely keep an eye on the adjustment knob at the top of the shocks as its super close!
If 80% of your driving is on the road any semi-slick is a waste and the AD08 or R1R is probably a better choice. You'll not get the benefit of semi-slicks but, you'll have all of the drawbacks of cost, fast wear rates and lack of tread. More road friendly tyres won't look as blingtastic though.
Everyones cars are slightly different then everyone has different ride heights and geos. I have no experience of 235 tyres only what i have seen on others cars but i would imagine on my setup they would be fine. Some shocks dont have the djustment knobs at the top so would be fine. I think you need to way up whether the benefits outweigh the negatives. Haggi has said he only plans on doing a couple of trackdays a year so for me the negatives well outweigh the positives when the car is going to be mainly used on the road.
Dont forget about tramlining either. My car is all over the place on the road.
Thanks for all your help so far guys as there been quite a bit of stuff i didnt know with fitting the wider wheels I take its there no way of taking the adjustment nob off the suspension? I was thinking that i might have to do something with the handbrake cable as its close now, let alone with wider wheels/tyres. Im going more for the AD08S as its more suited for my driving and the amount of track days, but the kumhos Ecsta XS KU36 dont seem to be much difference on the AD08S and there cheaper too. Anyone have any experience with the 2 types of tyres? The reason i want to go wider is for that extra grip with the power i have as it all makes a difference (and the wheels also ) Tramline i can live with as my car does it quite a bit now with the setup i have.
