I got a 2:00.65. Not very fast, I was hoping for a 58. Got some work to do there.

Ric has done a 51 in his AMCHAMP car which is roughly stock weight and runs a stock motor. He can't even run extractors. On meadum Hankooks
Ric has also done a 46 in the RX8 SP which was a heavy 1500 kg. Not sure what tyres
Dave Waldon has done a 46 in his 13b PP IPRA car which is at least 1225 kg (minimum class limit) on yoko A050
Richard Opie in the first shakedown round 1 with his 13b PP IRRA car did a 1:53.2
Bruce Henley in the same round as Richard Opie 1:49.4 (In IPRA, I think that it is Dave Waldon's old car, can anyone confirm)
Mods:

Early model housings, pp exhaust ports, side exhaust ports blocked off

Offset camber bushes in front control arms

Brapper, it is surprising the Hankook guys did not recommend RS-3s for those doing a reasonable amount of road KMs. I have tried RSRs and RS-3s, and the later are much better IMHO. Yoko Neova AD08Rs are good too, but much more expensive. I now use medium compound A050s, but 'only' because my road KMs are very low.

Medium A050s are defiantly on the shopping list. How do the compare to the others you have used in feel and raw lap times?

Mate, I have only really used them on a wet Wakefield track in 2015 so far at the 2015 RENEW Rotary Nationals. But they were still impressive. Be warmed that what you gain in dry traction (which is substantial) you tend to loose to some degree in wet traction.
