a RST s2 is a 3.82 final.


ps, my runs 195/45/15's,

On my old s2 std rst gearbox when at brunters i done @ 6200rpm(rev limit) i did 2x 133mph by half way @ brunters @ the PF fiesta thrash my snoopper read 135mph, and the racelogic read 133.3 mph.
but on same gearbox, with a different spec head/cam, i have done 140 on my snooper up hill, and on flat, @ 6500 rpm, and passengers.

And with the new box, @ 5900 rpm my snooper reads 143mph
