I paid 400 pounds for the tranny and 130 pounds for the clutch. I was wrong about the 4th gear speed too, its actually 117mph. it does the same revs/speed in fifth too, and thats 5,400 rpm at 100mph (on the clock)
Thanks for the help!
1 more quick question, how much do 15's to 17's wheels wise make differance in terms of speed?
