STI vs WRX rear hubs... are they the same?

[keeweechris]

Hi,

To fix a rumbly rear wheel bearing, I thought it would be a good idea to swap out the whole hub, instead of buying a new bearing, disassembling the hub, and having it pressed in. Cheaper too.

So I got hold of a V3 (1996) sti hub, done only 90,000km. My car is a 200,000km 1997 wrx. Does anyone know if there whould be any issue with a swap?

Cheers.

no issue. will bolt straight on

Phew! Thanks.

Do you also know if similar age Legacy's use the same hubs? The guy who sold me the STI one seemed to think so. Pick-apart has heaps of 4wd Legacy's, but no 4wd Impreza's.

yup they are the same but get gt ones as the brakes same as wrx. gtb use a bigger rear brake

is that the disc size or the hand break thing is different as well?

i saw this on a silvia once where they mounted the factory calipers on bigger discs - is tat possible on the wrx/legacy?

depends on what year your talking about pappu. my v3 sti ran the R160 handbrake. ( so basically, what im saying is match the handbrake/ hubs to the R160 or R180) they are same same through this catergorisation for the early four pots. The brembo rears are a bigger rotor again compared to older two pot rears.

its the drum internal diamater that changes pappu - R160 requires internal 150mm shoe and drum, the R180's require 170mm shoes and drum. then work out what calipers you are applying, single sides, twin pots or brembo twin pots to get the correct rotor diameter.

any combination is possible - the hardest is R160 with brembo twinpots - as i found out when i did my build. (smallest drum measurement with largest overal diamater is rare)..

and equals the most expensive rear disc doesnt it? haha

[funkytown]

dunno man - never had to price up the others

its also the lightest rear end set up to run with dccd..

oh and ... the other bits a miles cheaper comparatively so I'll take that battle on the chin

Leaving it how it was with sliding caliper & small discs would be far lighter than using the massive Brembo sized discs
