if you have two sets of alloys go for slicks, but if you do go for slicks a baffled sump is a must. I'm running as much -ve camber as possible and -25mm ride with the offside +1mm. R888's are great so far but not been on the track. Seemed to fair well on the 1/4 mile too one warmedgot price 2day for diffe, flywheels and clutch 2000 plus vat. so will be gettin that done in march. There not bad on the track r they i was surprised there was not much over takin me. just a shame couldnt get power down but that will all be sorted for next year. Have u had the 888 on the track yet. i was thinkin about buyin sum slick for next year.
