hadvw Posted April 28, 2016 Share Posted April 28, 2016 Totally in the same boat. Plus with the recent pictures, not all of the pad being used is a total deal breaker. I picked up a whole front brembo setup for the same price as the ATS which just made more sense to me. Were you already on 18s? Or do the Brembos fit under 17s?

iNfEk Posted April 28, 2016 Share Posted April 28, 2016 STI brembos fit under 17x7.5 +53 I believe. Which is the size of the JDM Split 5's on an Impreza. Not sure how it correlates to an LGT. Stock 17s definitely won't fit BUT since I got the wrong size caliper it could be possible. The inner barrel shouldn't step down like the 04 STI BBS wheel though.

element899 Posted April 28, 2016 Share Posted April 28, 2016 Were you already on 18s? Or do the Brembos fit under 17s? I'm currently on 2011 WRX's, just need a small spacer to be able to fit the STI Brembos. Link to comment Share on other sites More sharing options...
Phillip J. Fry Posted April 28, 2016 Share Posted April 28, 2016 what super performance tires are people going to use with this possible brake setup? Link to comment Share on other sites More sharing options...
Phillip J. Fry Posted April 28, 2016 Share Posted April 28, 2016 Not fitting on stock 17s (even with spacers) kills the interest for me. Car is 11+ years old. Hoping it runs another 2-3. Looking for a newer semi-DD/track toy (thinking used cts-v) with lgt as backup. 18s + this would be $3k easily - car isn't worth $3k. I did just pay $2k+ to repair front diff + add hexmods f1, but that wasn't really an 'upgrade', more a 'keep it running' cost. yup i firmly believe people should get better pads and stock/upgraded rotors. stop complaining about dust. its a necessity in order to have a good pad. chipping the corners off of a square wheel to make it round is simply counter productive.

iNfEk Posted April 28, 2016 Share Posted April 28, 2016 Good tires, pads are mandatory. They make the world of a difference. Dust is inevitable. Though there are some pads that dust a shit ton like axxis ultimates. Loved them but a lot of dust. I'm using Hankook RS3 right now on my STI. I've used BFG KDW/KDW2, Bridgestone RE11, RE01R and similar tires. I'm actually using BFG Sport Comp 2 on the LGT right now. Link to comment Share on other sites More sharing options...
hadvw Posted April 28, 2016 Share Posted April 28, 2016 I'm running Pilot AS3s (before that, AS/AS+, before that other decent tires). For pads, I've liked the Carbotech Bobcats the best - better (IMHO) than Stoptech, and WAY better than HPS. As for calipers - my main reason to want an upgrade is that even after replacing both fronts a few years ago with rebuilt units, I'm still getting a bit of pull now and again to the passenger side under heavy braking.

iNfEk Posted April 29, 2016 Share Posted April 29, 2016 Carbotech bobcats are great pads! I had them in my stock brake setup and in the brembo setup and hopefully they make a set for the ATS setup. Link to comment Share on other sites More sharing options...

Bobcats are clean and quiet. They aren't great at dealing with heat. I was able to smoke them pretty easily in only two runs at a Track-X event.

I was able to smoke them pretty easily in only two runs at a Track-X event. They're a street and auto-x pad only. I've never heard of track-x before so i'm assuming it's an open track racing like super lap or similar. I wouldn't ever run bobcats there due to their heat rating. Bobcats are awesome pads for the street. granted for track days I use axxis ultimates or similar track pad along with running dot4 fluid.

derp Posted April 30, 2016 Share Posted April 30, 2016 I wonder if they'd work with my PF01s. I could suck start a snow blower. Link to comment Share on other sites More sharing options...
iNfEk Posted April 30, 2016 Share Posted April 30, 2016 My findings of not fitting under 17s are because the stock wheels are 17s but the way the inner barrel is will be the problem. I'm quite sure that these can fit under 17s because STI brembos do fit as long as you have the right inner barrel and the spokes don't come in too much. If I had another set of 17s to fit once my replacement calipers (read: correct ones). I know my friend has a pair of prodrive wheels I can fit up to verify. I'll also verify if I can find some RPF1s as well locally to verify. I have an STI spare tire I'll check that too that's 5x100 Link to comment Share on other sites More sharing options...

fotofan Posted April 30, 2016 Share Posted April 30, 2016 I would still like to know what happens with spec.B 18s. I'd be okay with needing a small spacer probably...I don't mind changing bearings I put something here like all the cool people, except there's nothing cool to put here.

iNfEk Posted April 30, 2016 Share Posted April 30, 2016 Back to stock now till the correct calipers come in. Anyone that's questioning going back to stock... This is why I chose to use the nut and bolt vs tapping the lower. Link to comment Share on other sites More sharing options...
dieselsquid Posted May 1, 2016 Share Posted May 1, 2016 what we need is: 172-2586 & 172-2587 what I received was 172-2592 & 172-2593 (these are for the 2013-2015 XTS) they are definitely bigger than the ATS version. the rotors and pads are the same though! So now i wait till i receive the correct ones (hopefully soon) and I spoke with Amazon and they'll be issuing me a refund for the wrong ones even though I had them well beyond their return and refund window! the bracket works honestly. If i had bigger rotors it would've worked. Just so you know the Cadillac part numbers are: RF 22760031 LF 22760030 Just got mine and they were stickered as such. Cross referenced to triple verify. All good -Squid Link to comment Share on other sites More sharing options...

The ACDELCO part numbers is what I posted. They're the same as your cross reference parts. They definitely sent me the wrong ones and that's why they took it back. Correct ones are in route already.

I found some pix online...I think the spokes have a slight concave shape which would help. Don't have my car with me so not sure how much room there is between the stock caliper and the spokes though. How much wider are these Brembos than stock?http://uploads.tapatalk-cdn.com/20160501/eacf7ab71b01919cc4a816799f7051f8.jpghttp://uploads.tapatalk-cdn.com/20160501/11b683968fac1d503ce1bb31e9fbbaae.jpg I put something here like all the cool people, except there's nothing cool to put here.

They have Saab centers in that pic. My friend has a 92x as well. Anyway, the inner barrels look promising. You may need a spacer 5mm or so to clear but you've got good chance. The brembo sits beyond he top hat of the rotor. Link to comment Share on other sites More sharing options...

Like I said. You may need a 5mm spacer to clear. Link to comment Share on other sites More sharing options...
