Lightbulb Legacy Gt Brake Upgrades

Hey all, I'm interested in doing a brake upgrade for my MY99 GT Ltd. I was looking at the SYMS/Brembro 4pot upgrade. Just wondering, if it would be feasible/possible to retrofit the rear single pots with the the OEM front 2poters..? I wouldn't want the braking ratio to severely favor the fronts?

Any ideas or has anyone else done anything else?

BTW any1 know if our Behemoths! actually weight upwards of 3000lbs???

I've upgraded my brakes on my GTB, both front and rear.

I kept the same calipers but fitted larger discs and spacers - the difference in braking is incredible

At the front I have 315*28 8 groove discs with EBC green pads and the rear has 312*20 with 8 grooves and standard pads. I also have braided hoses all round.

Initialy I just upgraded the front, but the car feels more balanced under heavy braking now.

All discs have alloy bells, with the rears having the drums built into the alloy bells.

I would have thought it would be difficult to fit the front calipers to the back, as you would need discs of a particular size and special spacers to allow he larger pads to fit a disc that also fits around the drums

YIKES! Mebe not the SYM upgrade, maybe some other Brembo upgrade kit....The SYMS kit i saw for just the fronts was $2800!!! ack!

I most likely might just upgrade the front rotors and pads and probably stainless lines. As for the rears, keep stock rotors and upgrade pads? or might as well get Xdrilled?

Paul, how do you like those EBC pads? DId you also get your rotor cadnium plated? I made the mistake of not getting my rotors plated last time, rusted too easily...

The green pads are very good, very little dust, lots of bite and good when they are hot - only downside is they were no good after washing the car forthe first stop.

I would go for grooves rather than xdrilled, just as effective, less likely to crack and quieter

My discs aren't plated, but I've never really given them much chance to rust

My MY00 GT Wagon weighs about 3450 pounds, according to Subaru. Not sure how much lighter, if any, earlier Legacies are.

Difference between the sedan & wagon is about 80 pounds, IIRC.

My '99 Legacy 2.5GT 5 speed sedan weighed in at 3250# with me (about 190#) at the dragstrip scale. I think the gas tank was pretty empty, so add another 100# or so for a full tank of gas. Also, isn't the Limited automatic only? If so, add a bit more for that, too. Now that I think of it, I believe the owner's manual has weight specs for all the different models, so you could check there.

As for brake upgrades, unless you want to spend and arm and a leg there's not too much you can do. A guy with an Impreza just had Wilwood calipers installed up front, and I think he may have moved his stock calipers to the rear - do a search of the General and Technical forums for "Wilwood" and you should find the post.

As for my car, my first brake mods were Mintex 1155 pads and Goodridge SS brake lines (car had about 22k miles at the time, so stock stuff was still in good shape). The Mintex pads made a HUGE difference - excellent bite, cold or hot, wet or dry. VERY dusty, though, and sometimes squeaky at low speeds. Since I had the pads and lines done at the same time, it's tough for me to say if the SS lines made any real difference, but supposedly they help to maintain pedal feel as the car ages.

My next modification (perhaps this weekend) will be the installation of some new front rotors. My stock rotors now have about 26.5k miles on them and are pretty badly warped. When I had the new pads installed, the rotors were turned and the guy told me they didn't have enough material in them for another turning, so I went for new rotors. Anyway, the rotors have been cryogenically treated, which makes them stronger, more resistant to warping, and longer lasting. Check out www.frozenrotors.com and www.onecryo.com for more information.

I talked to Mark at Diversified Cryogenics - he and I agreed that although slotting looks cool, I just don't need it for street/auto-x/sporadic open track duty. Slotting would have cost about $90 extra I think. As it is, I got OEM Subaru rotors treated and shipped for $274 - pretty expensive, but I've gotten word from a few different sources that cryo treating really works, so I think it will be worth it.

Question

Paul, who makes the kit you used? I assume you need to use 17" wheels with this kit, I am running 17" Speedlines but I also use the stock 15" Turbo Legacy wheels for TSD rally use. Would a kit using uprated rotors that fit inside my stock 15" wheels improve my braking?

TIA

Pat,

Actually no, My GT Ltd does come in 5spd.
According to my registration the car weight rating is 3130 lbs. But you never know how accurate those meansurements are unless you actually weigh the car. I'm still trying to figure out what else Subaru has thrown into the Legacy GT to make it about 800+ heavier than the Impreza? Sound deadening???

As for cryo rotors, why not opt for the cross drilled ones? couldn't hurt? The cooler the better? I've heard that slotted rotors tend to wear down the pads faster than xdrilled. The slots "shave off" a layer from the pads ( )?

Paul- Where'd you get your rear rotors from?

When I eventually scrounge up enuf monay I'll definately get my rotors cyro-frozen. I've heard nothing but good things about stuff cyrofrozen. Any comments about cryo-freezing pads as well??

I think I'll prolly stick with stock calipers but upgrade the lines, pads and rotors. It's not like I'll be drafting Mario Andretti....

Hi

I got both front and rear kits from the same place - Hi Spec Motorsport in the UK

They use plain wilwood discs and will add grooves/xdrilling as required

They machine their own bells and caliper brackets and will do conversions using the existing calipers or Wilwood/AP calipers

Originally I was going to have 335*32 discs with Wilwood Superlight calipers at the front - but these would not fit under the Subaru 17" wheels (not enough clearance discs to hubs) The Wilwood Dynalights would fit, but Hi Spec say that they are a bit small and would be no advantage over the Subaru 2 pots - I am very pleased with the brakes I have

You do need 17" wheels for the Front Kit I have (I think it may fit undersome 16" wheels)

Chris,
Everything I've read says that cross-drilling just weakens the rotor too much, making it prone to cracking. I guess getting the rotors cryo treated after having them drilled might make them less susceptible to cracking, but you'd still have a few dozen stress magnifiers around the rotor. With me driving almost exclusively on the street, it might not be a problem, but I don't want to worry about it.

From what I've read, the only way to do it properly is to cast the rotors with the holes already there (as Porsche/Brembo does for their OEM stuff). However, I don't know of any companies that do that for Subies.

Last but not least, I just think something like cross-drilling would be too much for a 165hp 4 door sedan - kinda implying the car was sportier than it really is, ya know? That's why when I painted my calipers, I painted them aluminum (to match the rims) rather than some bright color. Same thing with my exhaust, too - whenever I do replace the muffler I want something that sounds good but doesn't sound too racy. It's just my personal preference I guess. I could see slotted rotors looking good on the Legacy (as on Paul's website), but cross-drilled just doesn't look right in my mind.

I agree totally - my first discs were xdrilled , looked good till I saw them on the car then decided they looked rather naff!

I was told that the Xdrilling is slightly better at removing gas than grooves but not significantly! Can also cause cracking

I found that the drilled discs chewed my pads really quick and were much noisier than grooves (curved grooves are supposed to be even quieter)

Don't go for grooves and drilled (or those daft Tarox discs with 40 grooves) because you will be loosing too much pad area and so will have less braking effect

Thumbs up

Pat-

I had a good experience with cross-drilled rotors on my last car. I had carbon-fibre/Semi-Metallic pads with it. I didn't have any squeek issue or excess wear. But then again I only drove about 20k on them so I wouldn't have known if they were durable enough. I can see what you mean about xdrilled on a Legacy. I'm looking for more performance than looks.

Any ideas where to get some Sloted Rotors?

Try looking up www.kvrperformance.com, they have just about everything in terms of performance braking.
