Wouldnt it be a lot less hassle to go for thiner rear tyres? This is why I binned my 245's and got some 215 on the rear. I thnk 225's would be idea and still clear.
Have you seen the pics of Ryan's old shell? He had the whole area removed and a plate filling the hole, i think this was how it was done on the BTCC cars, i will fish a pic out if you like?
appart from that I have not seen the kit removed im not sure how they mount, PM Porkie as his arches are removed and the kits stuck on.
