You have suspension on your car, you can definitely go stagger and get a wider rear tire like Shamu said. Yet it would be a waste to not get a big front tire for autox. With the stock diff, you will most likely get the one wheel spin anyway.

One of the problem with the R888 is that it is a tweener. It is not fast enough to compete with the R6/Z214, it isn't streetable enough to compare to the Pirelli Corsa/Trofeo/Pilot Cup. Also R888 is marketed as a RA1 replacement. For those who ran the RA1, they can tell you how much longer the RA1 last and how much more consistent they were. You might be getting what seems to be a long life on your R888, but there is a huge dropoff in performance after the initial couple cycles that makes them not worth while buying or keeping. New R888 is faster than new RA1, but old RA1 is faster than old R888.
I bought three sets of used R888s and then I finally woke up and decided it wasn't worth it. I did test a set of old R888s and a set of Z1s, I think I was 2-3 sec faster with the R888 at VIR off the top of my head. A guy running a set of BFG R1 was 2 sec faster than me in the same car with about 15 more HP.
