I am looking at getting a set of Bridgestone RE540 for my unused OEM rims for future track day. I know some people would not recommend them for the wear rate but I can get better deal with only Bridgestone tyres 
The RE540 only comes in 205/50/16 and 225/50/16. Are these OK on the S2k? Is this what you guys have been using? Any problem with the 205/50/16 at the front?
Are these helpful in Motorkhanas, where you tend to sit around for ages and then only do a few brief laps? Do they get heat up quick enough to give any advantage over street tyres in this event?
Many thanks

Hmmnnn; Perhaps talk to slick about this. You should first confirm the sizing. I could be wrong but I thought the RE540s came in 205/55/16 (front) and 245/45/16 (rear).
However, sizing aside, the RE540s are definitely one of the best track tyres for the S2000. YellaFella had them on his. Yes, they have better grip but they will take noticeably longer to warm up than road tyres or Toyo RA-1s. (IE about 5 Kms)
So, they're good for track work but for motorkanas the Toyos might be best because of their much faster warm up rate. On a mid-winter's day on a cold wet surface everything is going to be slippery no matter what you do.

i'm thinking of getting the RE540 for the OEM rims as well or TOYO RA-1s which ever comes with the right size & price. Please let me know H9K how much you could get the RE540 for?

If you choose the 225/50R16 it will be cheaper because they are the control tyre for a Commodore/Falcon racing series that Procar runs. The volumes sold mean they are available at a discount. Because the front wheels on the S2000 are not driven I wouldn't expect any problems putting the slightly lower profile tyres on the front. Also the 225 is likely to be perfectly adequate on the rear. Depending on your driving style you may want to adjust the handling balance with anti-roll bars. A slightly stiffer front might be a good option with the 205/50 front and 225/50 rear combination.

I thought they came in 205/55/16 and 225/45/16. ie. perfect match for the front but tnot the back.

Yellafella has been using 225/45/16 to a very good effect. The only 'problem' with that sizeing is that your speedo will be about 4% too optimistic (ie. will be showing 104kph when you're doing only 100kph).
Also the 225 is likely to be perfectly adequate on the rear.
One more thing, I have measured the contact patch on the 225/45/16 tyres, and it is a lot wider than any other 225s. About 1cm wider than the OEM S02s (or RA1s) at the rear.

There used to be only 205/50 and a 225/50. Now they make 205/55 and 225/45 also (http://ms.bridgestone.co.jp/ms_tyre/ms_top.../540s_size.html), but whether you can get them in Australia is another matter. As I said, the 225/50 is cheap because of volumes sold here.
