Dave ,
just an update . Tested on Saturday .
You were right re gearing it did feel a little soft through the top end .
But the 60 wasn't that much different to talk about .1.542/1.541/1.532/1.543
I was wrong in that I didn't pick up any MPH .
I back to backed the 30x9 against the 275 both Hoosier radials , the 30x9 is several years ,maybe 5 or 6 , old and the 275 about 55 passes and gone after the last pass .
the 30x9 went 6.920/919 @98.71/98.59MPH( 1/8")10.936/942@121.07/120.93MPH . 733/794 DA
the 275 went 6.880/886@99.14/99.30MPH(1/8") 10.881/884@121.85/121.90 MPH. 387/405DA
Car obviously likes a little more gear
thanks again,

Tex
