Final drive ratio questions
Hi all although im breaking my impreza i actually have another subaru that im building a justy (suzuki swift ) ! ha. But it
the justys weak link is the rear differential being small and open centre
the final drive on the justy is 3.416
impreza one ive seen is 3.511 ?
there is also a bmw diff ive found that is 3.45 ratio
my question is to any drivetrain gurus out there how much tolerance is there beetween the two?.
one guy has used a impreza rear diff but had to use different tyre profiles to balance out the rotational difference im not a fan of that personally as it limits tyre and wheel choice.
the bmw diff works out 0.04 of a rotation of difference does that increase with speed ?
only other thing i have considered is getting a custom final drive made for the subaru rear diff to 3.416/3.41 but not even sure who to ask about that
all advice appreciated
thank you
