the QTP's arent radials..they're bias ply DOT slicks..basically Hoosier's version of the ET Street bias ply tire..i'm done with radials..they hit too hard and they break too much ,especially on a stick car, and i cant afford to have my stock t5 laying on the ground in pieces lol
when i first started takeing my GT to the track, my mods were 3;55 gear, motorsport shorty headers, off road 2 1/4 h pipe, dynomax cat back, under drive pulleys, k&n cone filter, and cobra 1.7 rockers...26x8.5 et drag slicks, launch at 5500 rpm..
1.71 60'
12.75 @104 1/4
every thing else stock...
heads, cam, intake, throttle body, injectors...ect....
so with that mod comparison...
just sounds like your 60; needs to get better...
