Morning all... I've got my first track-day in the RS250 coming up in June (25th at Snetterton if anyone's interested) and wanted to know what sort of preparation is recommended. It's not my first trackday so I know how they work, but the last few trackdays I did were in my old Golf R that was barely a year old so everything was in pretty decent condition and I don't want to miss some vital check beforehand and have a crap day due to a failed x/y/z. The car has developed a bit of a mechanical whine in the last few days that is linked to road speed (not engine speed) which makes me think I've got a wheel bearing on the way out. When I take it to the garage I was going to ask them to check the rest of the suspension / bearings out as well as a quick check of the bushes. Is there anything else it's worth asking them to look at at the same time? It's been serviced (by the selling dealer) less than 1,000 miles ago but I guess that would have been a fairly bog standard oil and filter change, unlikely to pick up much more. My car also didn't come with a spare wheel, though I do have a new can of tyre weld. Would you be confident tracking it without a spare on board? What about the brakes? It's a cup and just has the standard set-up. How is this likely to fare on track? Anything else obvious that I'm missing beforehand?
