I strongly dispute this!.. I think, exactly what the XR8 & FPV's are lacking is lower ratio diff dears! 3.7 ideal all rounders, even 3.9's for the 1/4. No doubt you'll lose the 1800rpm at 100kph (more like 21..2200rpm) But the gain in acceleration would be enormous, getting completely rid of the "bog down" effect now present with the tall 3.23's.TS 50 said:If you put a 3.7 ratio diff in you might loose speed to 100km/h because instead of changing gears once from 1st to 2nd you will proberly have to change twice up into 3rd before 100km/h. 3.45:1 ratio is standard on an auto xr8 ute and option on the manual otherwise you get a 3.23 ratio standard.

How do attain 6200?...WBT56 said:All BA V8 run the M86, including the ute. No ratio lower than 3.46 is available AT THIS TIME. Expect to see 3.7 in the Ford product soon, and possibly 3.9 or 4.10 in the GM stuff not too far after.
100km/h should be about 6200rpm in the manual, in second.
Expect first to possibly be somewhat landcruiser like in the manual.
Rod, check this out. SPicer Axel is Dana in Australia. This is the product list pagerod said:greetings all
