Changed the rear pads today to some red stuff items, I was going to upgrade the rear brakes to some larger items but with the reduction in weight at the rear end combined with the reduction in overall mass i feel that the rear brakes are probably going to be fine. To give them just a bit of help I have changed the pads to red stuff and removed the rear brake dust shields. The dust shields were pretty rotten anyway and that gets rid of another 0.5Kg and it's unsprung weight too. I have been trying to decide on a tyre selection for the track for a while now. Initially was going to be 255/35/18 NS2R , They would fit on the 8.5 x18's fine but I am pretty sure I would have to do do something to fit the outside edge of the tyre inside the arch. They would also be very close to the strut as the Gaz Gold strut is a lot thicker than the OE one which has a flat on it. Going to a 245 would give up a small amount of grip but make fitment easier, slightly lighter smaller tyres but they don't do an NS2R in that size damm. They do a Federal RSR 595 which I have used before and they are OK but would I want to run around on a wet track with those on, I was trying to avoid having 2 sets of tyres. Looking at tyres on high performance cars the Michelin Pilot Supersport looked good. The 245/35/18 is fitted as standard to a lot of M cars and other high performance cars. The TT is a lot lighter now than these and doesn't run as much power as an M240i which uses these on the rear. Looking at reviews people seemed to get good on track performance with them. Came across an auction on Ebay from the BMW store for brand new 2 X 245/35/18 92Y MPSS for £147 delivered, less than £75 a tyre. Bargain I thought. Ordered 2 lots , so 4 tyres in total for just under £300 . Later decided that I would buy another pair as at this price I could sell them on if I didn't use them and still make some money. They arrived on Monday , All 3 of them :evil: :evil: After looking on Fleabay the original ad had been changed to 1 x 245/35/18 . After several E-mail exchanges with the BMW store they are going to honor the original ad, seems it was human error , which is what it usually is 95% of the time when this sort of thing happens. So another 3 tyres should be winging there way to me. These tyres are close to the best road tyre you can get and in tests I have seen aren't that far off the ultimate pace of an NS2R. I can't believe how hard the sidewalls/ bead are on these , I bet the tyre fitters are going to be cursing me. As new they only come with just over 6mm of tread in the outer groves and 7mm on the inner grooves so another nod to performance and handling. And at 10.1Kg they are light for this size of tyre, a 245/35/18 RSR weighs in at 11.8Kg when new. Hopefully get them fitted next week , 1 more thing ticked off the list.
