Ok, thank you for the replies. I'm hoping Juco will pick up on this thread and post up his thoughts.
Next question Once again on the same 18 x 10 rims, which of these 2 tires do you all recommend purely in terms of performance on the drag strip.
1. Mickey Thompson ET Street radial II 305/35R18, 26.4" diameter.
2. M&H Racemaster 275/45R18 28" diameter.
The car in question is a 2005 GT Automatic with Whipple HO making approx 460RWHP. Stock springs and dampers. BMR UCA, BMR LCA's. Dynotech 1 piece D/S with BMR safety loop.
The owner is a keen drag racer but it is also a street car. Biggest problem on the strip is traction at launch. Currently running 285/30R20 Toyo Proxes T1-R's. Best time around 12.60.
Would really appreciate any advice on this.
Andy.
