nyrm98 Posted February 23, 2011 Share Posted February 23, 2011 What is needed to install a front Brembo brake kit on a 2007 LGT? Can I just buy a Brembo kit from a STi? Help would be GREATLY appreciated! Link to comment Share on other sites More sharing options...
FocuS Posted February 23, 2011 Share Posted February 23, 2011 I think they are pretty much plug and play...you may need longer caliper bolts to fasten the calipers to the stock mounts? I also suggest upgrading to SS brake lines while your down there...and making sure your wheels will clear.... Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 23, 2011 Share Posted February 23, 2011 You need wheels that'll fit, tires for those wheels, the calipers, 5x100 rotors, and the bolts that hold the caliper to the knuckle (they are NOT the same as the ones you have stock). You'll probably want pads too.

nyrm98 Posted February 23, 2011 Author Share Posted February 23, 2011 So that is it? It seems too simple. Any specific years of STi's that I need to buy them from? Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 23, 2011 Share Posted February 23, 2011 Calipers from an 04-07, rotors only from an 04. The fronts are easy. The rears become SLIGHTLY more complex.

nyrm98 Posted February 23, 2011 Author Share Posted February 23, 2011 Having just front Brembo should not cause a problem though right. And I appreciate the help! Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 23, 2011 Share Posted February 23, 2011 Nope.

rao Posted February 23, 2011 Share Posted February 23, 2011 Brake balance is highly over-rated. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 23, 2011 Share Posted February 23, 2011 Just run milled bars of soap as brake pads, and you'll be fine.

nyrm98 Posted February 23, 2011 Author Share Posted February 23, 2011 Thanks. Anyone out there have just front Brembos and no rears? Can I get some imput? Link to comment Share on other sites More sharing options...
FocuS Posted February 23, 2011 Share Posted February 23, 2011 I have had front Brembos and stock rears for 30K miles. The balance was a little weird until I changed out the rear pads since they were very worn. All is well now and braking distance is noticeably improved!

rao Posted February 23, 2011 Share Posted February 23, 2011 If the front Brembos make ANY difference in braking distance (and the don't until the stock front brakes have faded), then the balance has to be different since the fluid split front to rear is fixed. If the front Brembos don't reduce the stopping distance (which is the case), then what is the point of the swap?

BAC5.2 Posted February 23, 2011 Share Posted February 23, 2011 Bling... and worse fuel economy. Fluid volume split isn't fixed. Pressure is. I haven't run the numbers for Brembo fronts and OE LGT rears, but bias shouldn't change more than a percent or two, and that can be retained by using a slightly more aggressive (but still street) pad. The difference can be as simple as using an HPS in the front and HP+ in the rear. You'd see similar bias differences by running a "hotter" pad in the stock front calipers than the rears. To the OP, brakes have very little to do with stopping distance. Keep that in mind before dumping $$$$. Most people probably don't do Brembo swaps in LGT's because the stock brakes are actually pretty awesome. Personally, I have no justification for why I'm doing the swap, other than opportunity. A friend of mine owes me a set of calipers, and I need pads and rotors soon anyway. I already have the brackets for the rears even!

nyrm98 Posted February 23, 2011 Author Share Posted February 23, 2011 Opportunity is the reason I would do the swap, and of course the "bling" factor. As long as it didnt make my braking worse I am having a hard time seeing why not to do the swap. Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 23, 2011 Share Posted February 23, 2011 Well, it might. It's always a give-and-take. Big brakes take more time to get heat into them, making them inefficient at cold temperatures without the proper brake pad. Plus, they add unsprung weight, which hurts all aspects of performance. The best performing brakes are the smallest ones that will adequately do the job.

ssbtech Posted February 24, 2011 Share Posted February 24, 2011 The best performing brakes are the smallest ones that will adequately do the job. Which is why the factory Outback XT brakes are smaller than the LGT's brakes I think the biggest reason people who aren't racing the car do upgrades (other than the gold bling factor) is to have better feel and control over the brakes. I had a 2011 Impreza for a week as a loaner. The brake feel was much better than the Outback. In fact I almost crashed the Outback when I got it back because the brakes took a lot more force and travel on the pedal to slow the car down Link to comment Share on other sites More sharing options...
Spec B Posted February 24, 2011 Share Posted February 24, 2011 I think the biggest reason people who aren't racing the car do upgrades (other than the gold bling factor) is to have better feel and control over the brakes. ^^ Bingo. I am running front Brembo's with HPS pads and stock rear with HPS pads. There is a huge difference in feel with brembo's, I also feel a much better initial bite when I jump on them. I have not noticed any issues regarding the balance. Link to comment Share on other sites More sharing options...
nyrm98 Posted February 25, 2011 Author Share Posted February 25, 2011 Well I bought the Brembo front brake set. I guess I'll see what I think when they are installed. I am excited though! Link to comment Share on other sites More sharing options...
AZP Installs Posted February 26, 2011 Share Posted February 26, 2011 I ran my LGT on track with front brembos and stock rears. It was a nice improvement over stock. You won't be let down. Don't worry about the brake bias unless you are a professional race car driver. -mike http://www.pbase.com/paisan/image/91072632.jpg AIM: AZP Installs | E-mail: paisan@azpinstalls.com | 725 Fairfield Ave | Kenilworth, NJ 07033 "Race Tested, Enthusiast Approved!"

wpmarky Posted March 15, 2011 Share Posted March 15, 2011 quick question, are the bolts that mount the calipers to the knuckle the same size? I noticed last night that my bottom bolt was shorter than the top bolt. When I grabbed the bolt & washer that I bought from the dealer, and tried to install it in the bottom hole, it wouldn't go in all the way. It seems that my stock LGT bolt was a better fit than the longer one my dealer gave me. Can anyone else confirm? Link to comment Share on other sites More sharing options...
Underdog Posted March 15, 2011 Share Posted March 15, 2011 Did you try chasing the threads on the bolt to make sure it ran free? Are you sure it's the correct bolt? I used the STI bolts and had no trouble. Well, I did put an extra washer in between the caliper and knuckle like an idiot, but I fixed that.

AZP Installs Posted March 15, 2011 Share Posted March 15, 2011 The Brembos use different bolts to afix it to the knuckle than your stock caliper brackets. There are 2 different sets of bolts available for the brembos. 04, 06-11 and 05 The 04 & 06-11 are shorter bolts. The 05 is for MY05 STi Brembos which have a metal dampener attached (therefore longer bolts are needed.) -mike Link to comment Share on other sites More sharing options...
wpmarky Posted March 15, 2011 Share Posted March 15, 2011 The weird part is the one i got from the dealer (says '10' on the top of the bolt) does fit into the top hole, but not the bottom. The bolt that does go in all the way on the bottom hole says "9". That makes me think something is up with the caliper's bottom thread hole. I didn't try to chase the threads yet, i didn't have a chase or tap set. I guess i'll get one and see if that helps. thanks. Link to comment Share on other sites More sharing options...
Underdog Posted March 15, 2011 Share Posted March 15, 2011 I meant just thread a nut on the bolt, don't run a tap through the caliper unless you are sure it is bunged up and you know what you are doing. The Crimson Dynamo Link to comment Share on other sites More sharing options...
wpmarky Posted March 15, 2011 Share Posted March 15, 2011 The shorter one goes in smoothly. The longer one takes a bit more effort, and then stops leaving a gap in between the bolt head and knuckle equal to the difference in size between the longer bolt and the shorter bolt. I didn't look at the other side yet, had to stop early and get dinner. I'll compare tonight. I wonder if the previous owner helicoiled it without telling me?
