Can anyone tell me if I need an adaptor kit to fit brembos onto my 97 STI RA?
It has the large unvented discs.

Drop Ian Godney or Alyn at AS Performance a PM.

its a total pita with the solid 290mm discs and sliding calipers...........you'd be better getting the brake backing plates (or complete hubs) off a v4-6 car that had the 2pots fitted as std, then its basically a bolt-on job

I haven't seen any RA's with the larger rear discs , only the type R's , you sure you have 290mm discs ?

If you do , the easiest way to upgrade the brakes is to fit the vented type R rear discs , and late classic vented calipers off a 99 UK turbo , RB5 and P1 , these will fit straight onto your car , and the vented discs are easier and cheaper to get then the solid ones.

Other than that its as Alyn says , change the backplates from either a version 4 onwards type R or a 2001 onwards STi

Pretty sure they're 290's. I already have a full set of brembos lined up to go on so it'll be a case of doing whatever's needed to make it work. I might be able to get the backing plates if that's what I need.

Thanks for the help so far

Edit: been searching and everything I can find suggests that, year on year, the type R and STI RA share drivetrain components. So I'm looking at 290mm solid discs with sliding calipers.

your correct, specifically the STi RA shares the same R180 rear diff and brakes (from v3 to v6) as the type-R

if its a std RA then it simply uses a WRX chassis............

I had an RA STi and it had the 266mm rear brakes and 160 back end , I have put brakes on quite a few as well , and they all had 266mm brakes on the rear.

The only RA I have worked on that had 290mm rear discs was a very late one which had 2 pot calipers on the rear.

pukka STi RA's from v3> mirror type-R's, so not sure what you have had Ian but thats how they should be...............

the models do get very confusing as you get WRX based RA also and 4door std STi's that simply use the small R160 and std brakes

hope this helps, alyn

So if I get the backing plates from the same STI I'm sourcing brakes will it be a simple bolt on? Will the handbrake work?
Thanks.

yes handbrake is exact same...........
