I had 2 sets of wheels for my 3dr, RL7's with Parada 2's & hocks with R888's, used them both on track & R888's a lot better in dry & wet but not standing water, Parada's still a very good tyre in the dry, didn't use it much in the wet on the road but they seemed ok in the wet. R888's are a lot more noisey & harsh on the rd than the Paradas as very stiff sidewalls. R888's wear out quick aswell,only start with about 5mm & v soft & expensive ! Get yourself 2 sets of wheels. I've gone down the same route with my M3 (sold the 3dr) got 2 sets of wheels ,track/road.
