GH3 Rear Disk Conversion

I apologise if this has been discussed before but I saw nothing after quick search of the forum.

I have a 2009 GH2 impreza with rear drums. It's almost time to change out the shoes so I'm thinking of doing a conversion one time, mostly for looks, o have the look of drums. The car is totally stock except for some rims.

I'm getting a pair of bl5 disks, calipers and the handbrake assembly, is there anything else I need? I not familiar with Subarus so any advice is appreciated.

There is a version of your car that came with rear discs. It may be easier to get the rear spindles and hand brake cables from it.

Have you confirmed that the legacy setup can work on your car? And I see no mention of spindles

I am not 100% sure about the spindles, I will have to find out the guy I'm getting the parts from has them available.

The reason I am looking at Legacy parts is
1- parts for this model Impreza is stupidly hard to find, and
2- parts are kind of expensive.

I am hoping someone here on the forum can confirm if the Legacy setup will work, as a lot of the parts elsewhere on the car can be taken directly from the BL5 Legacy (trust me, the car got a front end hit and a lot of parts came from the Legacy including the fuse box, intake snorkel thing, condenser, radiator, intake manifold, fender shield and a few other items I can't remember).

If I see what is on the car now I should be able to confirm whether they can be replaced with those from the bl5.

Things to consider...

1.Bolt spacing of the bl5 is 5x100

2.Proportioning valve adjustments

3.I would assume bl5 rear discs would be larger than gh3 and may not be proportionate with stock gh2 front

4...not sure abt fitment of rear axels if applicable.

Gh3 is 5x100 as well as the bl5. So one less issue there

Mine is FWD so that eliminates the rear axle issue.

That means you have a GH2, GH3 is AWD.

I have GH3 rear disc spindles if you are interested. You will need to re-use your wheel bearing/ hub assembly and good to go.

Didn't I install the seatbelts and steering for you? Message me when you ready for the rear disc setup.

You installed the steering wheel bag and one seatbelt because my guy didn't realise the bracket was bent. I will message about the rear setup
