most cars in FH3 perform better in AWD form, which also means they usually need much shorter ratios and lower gears to fully utilize better traction, so no.
Even my 700PI close-to drag-tune Torana with stock tires 1500hp(V12+AWD swap), after testing extensively on drag strip it's at its best form with a 1st gear of ~150mph and requires 3 gears in total to clear the drag strip. So unless you want RWD stupidity for lower-than-S2 classes the answer is very likely no.
