So I already have the H6 rear setup on my 00 LGT. If I wanted to go with the vented rear rotor I would need to replace the caliper and bracket from an 05-09 LGT, correct?

What about the 00-04 LGT rear brakes that use vented rotors? I didn't see anything for this specific setup, just the 05+ LGT and the 00-04 Legacy.

Does the 00 - 04 LGT use different calipers or pads to make up for the thickness of the vented rotors? (I'm doing a complete brake upgrade in my 98 OBW, sticking with my 16" wheels)

The 00-04 LGT(at least in the US) does not use a vented rear rotor. They use either a 266 or 290x10mm solid rear rotor. The 05+ LGT moves to the 290x18mm vented rear rotor. Yes, the solid and vented rear calipers are an entirely different casting. The "H6" upgrade keeps the certain application stock caliper found over the 266x10mm rear rotor and mates it to the taller Legacy bracket to accommodate the 290x10mm rear rotor. The 05+ GT uses unique both calipers and brackets to accommodate the 290x18mm rotor.

I wish I knew where the heck I read the 01-04 LGT used vented rear rotors. I spoke with someone at partsdirectusa.com before I placed an order with them, and they confirmed from 01-04 the LGT used vented rears.

I guess it's going to be a surprise as to what I receive

Good thing I'm not in a huge rush.

No doubt it should be interesting. I wouldn't want to argue with the guys in the parts biz but in this case I would have to. There were no vented rears on that gen Legacy in the US market. In some overseas markets yes but here - no. Tell us what you get and post up the part number and I think we can help you sort it out.

Also IIRC if your vehicle has the stock rear setup and you want to get to a larger diameter rotor you have to replace everything(calipers, caliper brackets and rotors.)

All 2000-2004 Legacy's, Legacy wagon's (except Brighton's) and Outback Wagon's use the 290 mm solid rear rotor and D770 rear pad.

Some Brighton wagon's have rear drum brakes.

We'll see if I get vented or solid rotors, it'll be like opening a Christmas present not knowing what to expect!

Yes, I'm replacing the calipers and brackets - this brake upgrade is because two of my calipers are sticking and my rotors are shot because of them. The front is getting WRX rotors/ 2-pot calipers

Actually, he got the correct parts to the part number, mis-informed employees gave him the wrong info.

So it looks like at least 3 different vendors make the adapter brackets to mount the '06/'07 2 pots on older backing plates:
-Kartboy ($225)
-KNS brakes ($249)
-Mach V motorsports ($195) - although these look like they might be the same as the Kartboys

I can't imagine there's a huge difference between these brackets (other than price)...any firsthand experiences to share?

It's all good, they shipped out the correct vented rotors THE DAY I messaged them. They even gave me a prepaid label to ship the other useless ones back.

Hello there all, I've just upgraded to the wrx front brakes on my 1997 obs and now the car appears to have an oversteer kinda feel. Has anybody else had this experience after upgrading? Thanks.

Before I could install new Hawk pads on the rear of my 95 SVX, the left rear rotor was scored by the caliper. Since I need to replace the rotor (I could refinish but prefer to upgrade), I have tried to follow this thread but since the SVX is an older Subaru, most of the tread doesn't apply. I need some advice. I think I can upgrade the rotor to the H6 option but don't know if I can use the stock caliper or need to use a different one as well as the required brackets. I think H6 rotors are solid; I'd prefer upgrading now to a vented rotor. I'm a little confused with the dba STI vs H6 vs Tribecca; dba has 290x18mm also a 320x18mm while the H6 is a 290x10mm, not sure of the Tribecca and I believe Brembo make a 3??x20mm. I've found that there are "gravel" rotors (unsure what they are;advantages/disadvantages?). Also what 2 pot rear rotors from Subaru or aftermarket will bolt on w/new brackets (question of splash shields)? This is a spirited daily driver so over $1000/2/3/4/is out of the question. I know front upgrades aren't done because of hat specs. but I think the bigger rear rotors will help stopping. The tires (summer not winner) are 18" Yoko S drive.

So, I got the KNS brake brackets, and I ran into a slight issue when installing them:



It would appear that the head of the supplied bolt for the caliper to attach to the bracket is big enough to prevent the adapter bracket from aligning perfectly with the upper bolt hole in the knuckle.

I'd have to remove a hell of a lot of material from the knuckle to get it to fit - maybe KNS can chime in here?

Is that being installed on an LGT?

Yes, it is. Did I get the wrong part? Your website says these should work on Legacys up to '09.

The bracket works for Brembo's or 2 pots on Impreza's, it works for Brembo's on LGT's w/ some grinding - I'm just not sure exactly where. The pickup points are the same so it's just making clearance.

I can't quite tell anything from the picture.

It's not for Brembos, though - it's for the '06-'07 WRX 2-pots.

The bolt in the picture is the one that attaches the caliper to the bracket. It jams right up against the knuckle, so that the hole in the adapter bracket don't *quite* align with the hole in the backing plate. If I take that bolt out entirely, I can get it to bolt up no problem.

I know it's the 2 pots - but the Brembo bolts on the same ay so I am not sure what's the problem. I would have to look at the LGT boards to see where they are grinding. I'd bet it's the same.

Default Legacy GT 10-14 fronts?

Firstly, fantastic info here. Big thanks already for this.

Basically, I'm looking at a 2012 WRX and thinking about occasional track days. I want to keep the stock 17" rims, and from what I have read everywhere, the best performing OEM part from Subaru that bolts on easily will be the Legacy GT 05-09 brakes.

Based on the info in the OP, the Legacy GT 05-09 (316x30mm) would be a simple and excellent upgrade for the fronts. And I found the info on the rears had been recently added and that is a big help.

But I was wondering if the Legacy GT 10+ fronts would work? I googled around but couldn't find what size the Legacy GT 10+ front rotor sizes were or info about the calipers. So I was wondering if anyone had information on that they could add here?

And also, the follow on question is whether they are a simple bolt on with the same parts required as for the Legacy 05-09 fronts?

I thought it would be good to add the info on the Legacy GT 10+ to the OP, so decided to ask here rather than start another thread.

Thanks

PS: While I'm at it, what does the 2015 WRX have, and could it be retrofitted to a 2012 WRX easily? I think I read they have 5x114 bolt holes...?
