After reading some post and comments from here, I decided to go ahead with my conversion as well.
Getting information here and asking questions had been extremely difficult here, none have been quite accurate.

Here are my journey to convert my brake from 2p1p to FHI red WRX 4p2p.
Front is the easiest, just plug and play. existing rotor can be use.
The rear bracket I got it from KNS brakes, it's V2. As for rear rotor, I'm using the Forester XT SJG (MY14/15) model rear rotor.
The one that others mentioned using 2010 LGT rotor can't fit and won't work at all.

The stainless steel brake hose must get those that meant for WRX MY06/07, else the rear won't fit too.
It has been a good experience to get all this done up and I'm pretty happy with the upgrade.

Thanks for posting the follow-up!

What information did you find that wasn't accurate so that we can set the record straight!?

The rotor that they mentioned on previous thread, using LGT 2010 it's not correct. Which I bought and cannot be use at all.
The SS brake hose they mentioned also wrong, which I bought too and the rear won't fit.

So I have to buy another set which is meant for WRX my06/07 to fit.

If it's not fit or if you have not try them on, I would prefer not to guess it should fit.
This is brake conversion and it's safety concern, even KNS Brakes guys would not advise me what rotor to get just because they have not done it before.
There's a series of emails back and forth with them and I really appreciates them not giving me the wrong information.

Which model year WRX caliper were you using? Also, are you using the stock XV rotors on the front?

Thanks!

I'm using wrx my07 calipers. Yes, using stock front rotor.
The front is straight forward, just replace the calipers will do.

Would the 08-14 model year WRX caliper work as well or is the 06/07 the only one that is a direct bolt on swap?

This is awesome! Thank you for sharing. It's really great, that you've shown that they fit behind the factory wheels. I'll have to add this to my eventual wish list.
The factory wheel cannot clear the calipers, front and rear. So I added a 15mm spacers on both to clear them. You may add a 10mm to clear them too but I'm going for 15mm.
When you added spacers to it, you need to replace the wheel stud as well. I'm using the long stud for stability, bought mine from an ebay seller. HERE
If you do not wish to replace the original stud, you may need to add a thicker spacer to clear the original stud.

The rear knuckle also need to be grinded a little in order to fit the KNS bracket, just 1-2mm. I couldn't take a shot of the area as the tech guy done it so quickly and tighten them up.

Got my wheels changed due to the stress the spacers are giving the car.
Can hear my dampers sound hard when passing hump.
Sport wheels from WedsSport Jpn SA60M 18", offset +48, 8jj.
Got the tires profile changed to 225/50/18, the ride feels a lot better now.
Looking for lowering spring now, any recommendation?

Just a quick update on my brake upgrade.

Gotten a Brembo Gold rear calipers on the cheap together with 08 Sti rotors, so I contacted Ken from KNSBrakes and asking for info on the V2.0 bracket that I had.
Which is mounted on my current ride on FHI red wrx calipers, they work great.
Ken told me the bracket (Ver2.0) that I current installed would also fit Brembo calipers, only using different bolts. So I gotten the bolts.

Unfortunately, the bracket can't fit onto my Crosstrek MY2016 CVT. Or should I say the bracket is not meant for Brembo calipers, all the mounting holes are intact but the height of the mounting holes are not the same for Brembo calipers.
After fixing up the rotors, 316mm with 170mm handbrake diameter. The outer ring of the rotor is touching/grinding on the inner part of the caliper.
So to speak that unless I can find a rotor which is smaller than 316mm then the bracket would work. Tried also fitting with DBA-2657 rotor and they are with the same results.

I'm now looking at other brackets to try and test if they fit, will put up the link of the bracket if I can successfully convert my FHI to Brembo calipers.

Hello. Thanks for the information. I have a 2016 Subaru Impreza 2.0i CVT and would like to confirm the following for the front and rear:

Front 4 pot 06 to 07 WRX calipers
Front Impreza rotors
Front 06 to 07 WRX pads
Front Impreza stainless steel lines or do I need 06 to 07 WRX stainless steel lines?

I know people who did the front and they have stock brake line from their Crosstrek/Impreza.


Rear 2 pot 06 to 07 wrx calipers
Rear 2014/2015 Forester SJ XT rotors - Will this fit Impreza? Or is this because you have a Crosstrek?
KNS bracket -which version bracket - please confirm
Rear 06 to 07 WRX brake pads
Rear 06 to 07 WRX ss brake line? Please confirm

In addition this must be done to rear: The rear knuckle also need to be grinded a little in order to fit the KNS bracket, just 1-2mm

Pls confirm the above. Again vehicle is 2016 Subaru Impreza 2.0i CVT Canadian model and I have the red 06 to 07 WRX front 4 pots and rear 2 pots. Thx
