Hi

Yes they will but you will require either sti alloys from a 2001 to 2004 car as they are 5x 100pcd or some aftermarket alloys the later sti wheels are 114x 5 pcd (ie hawkeye later blob eye cars).so they dont fit.

The wrx wheels don't have the correct offset to clear the brembos.

the standard 4 pot brakelines fit the brembos fine

any more questions please feel free to ask.

If I remember right, you need the later offset model to fit a late Blob / hawkeye.
The Impreza switched from 100PCD (2001-2005(?)) to 114.3PCD offset later, which meant a wider track and apparently stronger setup.

A subaru mechanic did actually make a good point though when when I mentioned I was considering the same swap - he basically said unless you have the brakes refurbished, you really don't know what you're getting, and they're potentially the most important part of the setup - stopping you!
Given that Brembos cost a fair bit even second hand; once you factor in a refurb / checkover, you may also want to consider a K-Sport / D2 conversion instead.

I ended up going for new K-Sport brakes for that reason; they are BRILLIANT in comparison to the standard 4 pots; I tried 3 different types of pad on the OEM brakes, and even with braided hoses they were still far short of my expectations - the K-Sports, with Blue Stuff NDX pads, just work! HTH.

The OP has a Hawk WRX these are 100PCD, It was only the STi that changed to 114.3PCD

The discs and calipers will fit straight on , you can use your existing hoses as they are identical to the STi ones , but your existing handbrake is too small to lock onto the rear brembo discs as the STi has a 20mm larger handbrake size , so you either need the thicker handbrake shoes we have made , or the discs we do with the steel inserts in them to reduce the handbrake size down in the disc.

You will also either need wheel spacers , hub centric ones would work fine , or wheels with more room behind the spokes , I think its around 10mm the wheels have to be spaced out to clear

As stated above , the WRX wheels have always been 5 x 100mm PCD , only the 2005 onwards car changed to 5 x 114.3mm PCD

Hope this helps

Cheers for the clarification re the offset guys.

To the OP, if you're buying second hand brakes I'd still recommend you get them professionally refurbished by someone like Ian.
As previously stated though, by the time you've done that, depending on how much you pay for the second hand kit, you might end up better off having just bought K-Sports or D2's, where at least you'll have:
a) A guarantee, and
b) Peace of mind that what you're getting is new and unabused / damaged.

How much trust you place on what you're buying depends on how much you trust the seller I guess. Hope you make a choice you end up happy with!
