If you run the streets now, learn to drive on the limit of those, then go to semis youll be miles ahead time and money wise than if you were to continue battling on semis.

Russell: 38.4 around winton on 245 KU36
Richo: 38 same? i think
Me: 39.2 around winton with only 235 with more driving left!
Theyre fast tyres dude... and cheap!
