Default Front brake upgrade question

Alright. Well I am still looking at brake kits. I Don't know if I want 4 or 6 pot, I don't know if I want 2pot rears or upgrade to rex rears or what realy. I do know I need to be able to stop quicker. I am going turbo in 2-3 weeks and a track day in a month and a half. I also got a friendly track bet with my uncles turbo'd mustang(track prepped) on whos going to get better times.

Neways. Am I in for a hole-lot of trouble by upgrading the fronts to 4 pot and leaving the backs stock? Will that totally screw up this cars driveability? Is this possible? I am asking I guess because these 2500 buck brake kits are out of my budget by a whole lot. I could spring for a 1000 bucks but not much more...going to school and not making much as a part time editor isn't helping the fight to having "the ultimate newage auto rs " j/k

For about a grand you have a couple of options to improve your braking.

1. Subaru 4-pot front brake upgrade. These will run you $800 or so, maybe cheaper. Same diameter as the WRX rotor, give or take, but more pucker power due to the extra pistons. At the same time you might also upgrade the stock pads front and rear. That's an extra $200, maybe.

2. Stay with standard 2 pot front caliper but better pads front and rear, slotted or cross drilled rotors up front and the H6 rotor upgrade for the rear. SS lines all around and upgraded brake fluid. This may run around $700-$800 as well.

To tell you the truth, I'm not sure which of these two options would give you more bang for the buck. With option two you have the vast improvement of the rear braking ability plus the general improvement of braking due to the pads, etc. Option 1 gives you better front braking than the standard 2 pots (say, with the same high perf. pad) but your rear brakes are only marginally improved. Which gives us the 3rd option of:

3. Subaru 4 pot up front with H6 rear upgrade in the rear. If you stay with the stock pads, fluid, etc. you might be under a grand as well.

Moving to a 4 pot up front will not wreak havoc to your current brake balance.

what a great wealth of info...thanks!

I am leaning towards the 4pot in front (with WRX rotors?)and H6 rotors in back with good pads and lines (I guess I will go over but I rather brake well then" Enh"...if I am putting down the money) Also then I can upgrade the rears later to 2pots or something. Thanks for the info. If anyone has anymore to put in that would be greatly appreciated. Thankyou very much.

Now if I was going to get the 4pot where do you guys suggest. Mabye buy the h6 rotors off of subaruparts.com?

Yeah, I could not tell what kind of car he has from his car description. Nick, if you have an New Age RS then you have the rotors for the 4 pots already. All you will need are the calipers. So you save more money right there! And as Peaty said, the 4 pot rotors are the same as the WRX rotors.

OEM Subaru stuff can also be found here: http://www.1stsubaruparts.com/

There was a thread with all the part numbers for the H6 upgrade recently.

The 4 pots can be had here:http://www.wrxrsparts.com/ (this is "Sugar", Lisa from Troncalli Subaru)

One thing I am a bit conerned about is Subaru rotor's tendency to crack/groove so cryo treating might be a worthwhile investment if you don't go with better, though more expensive, rotors.

Happy hunting.

Ah, I thought new age rs rotors were the same at 98-01 rs rotors. Wow. Also these rotors I have now are pretty messed up. Lets say 1 lagit track day with re-92s and about 20-25 "trackdays" on an abandon race circut near my old school didn't do much to keep these rotors in a good condition.
-Neal

Thanks alot guys. I realy appreciate all the help. I came across the saying if your going to go fast...be able to turn fast and more importantly STOP fast. heehee. So I am going to live up to the saying.

The Subaru 4-pots are pretty good but they are really heavy calipers when compared to like Brembos or StopTech calipers. I have the StopTech Brake kit on my car and I like it a lot. It gives good and consistent braking all the time with no fade. I have the Subaru 4-pots mounted on my Legacy GT wagon and they work just fine on the car. I would recommend 4-pots if you plan to do a lot of spirited driving, track events, or autoXing.

Well I think I am sold on the 4pots. Now what about rotors? or would it be better to buy a 4 pot package from a vendor? (I am not good with what and who to buy from... I kinda get informed and then go...uhhhh now what) Again. Thanks guys. you have all been a big help. Soon I will be quick (relitive speaking) and stop quick.


on that branch...
What type of maintence is involved in them?

Best bang for the buck is the Subaru 4-Pots, no question about it.

Here they are on my car

Yes you can buy the whole package from one vendor. The 4 pots as a complete kit with rotors pads and calipers. You probably need new rotors, as yours sound like they might be toast.

I checked www.wrxrsparts.com and they have the 4 pot conversion as $695 for 93-01 models and $550 for the WRX. I'm NOT sure if this includes rotors, though I think it does. Check with them to make sure. You could also probably get the parts for the H6 upgrade from them as well since they are Subaru dealer. So one stop shopping is possible. If you want to get your rotors cryo'd before the install, something I am also considering, try http://www.onecryo.com/onecryo/motorspt-pricing.htm they are only $25 per rotor under 12" in diameter. This should alleviate the cracking and scoring that is common with the WRX rotors.

ImprezaWRXDriver's suggestion for Brembo's or Stoptech's are good but unfortunately out of your price category. You will get better heat disapation from these kits than from the Subaru 4 pot but they are money. Perhaps when you go through these OEM rotors you can save up some cash and get aluminum hatted rotors. These would also aid significantly in heat disapation and keeping your hub bearings from frying. That is a problem that some have encountered with the stock WRX braking system. The extreme heat buildup on the track contributed to premature hub bearing failure. The heat just went straight to the bearings and cooked the grease. The Stop Techs also have a superior caliper design that resists deformation during extreme heat and braking stresses.

I dunno, it all depends on how much track action you will be seeing as to your money allocation. If you are really concerned about brake performance and possible longevity then maybe brakes like the StopTechs are a good idea. they are about $1700 for the fronts. But before you go and do the rear brakes as well, you might want to read this: http://www.stoptech.com/whitepapers/...tter120601.htm

It makes sense but for the $200 it cost to do tthe H6 rear brake upgrade it certainly can't hurt to try it, right?

ah, well this year it is only 2 trackdays (my uncle has chalanged me to a dual...his v6 track built turboed mustang vrs my rs-t) but I am rely enjoying track driving...so I don't know. But for now I think the 4 pot fronts and H6 rear mods will do.

Yeah you should be fine with that set up. Don't forget the STI Version 1 and 2 used the 2pot front brakes that are on the GC8 RS's. And they had some 250 hp.

So are you going to be racing at Blackhawk or Road America? I used to live in Roger's Park as well as Wrigleyville when I went to SAIC.

Default Stoptech

highly recommend stoptech because

1) the piston size was designed with the rear brakes in mind so the brake balance between rear and front brakes is maintained

2) Excellent quality and design

3) Excellent customer service (one of the best out there)


http://www.stoptech.com

My take, given your budget;

Stick with the stock calipers up front, a nice set of slotted or drilled (as long as the holes are cast into the rotor, not drilled aftyerwards) do some decent pads, and stainless lines...it's really all you need.

The cost involved IMHO makes the 4 pots not worth the money. Yes, they look nicer, and yes, they do bit better than the stock calipers, but the rotor size is almost the same, and the pad size is almost the same as well....so fade on the 4 pot is not much better than the stock caliper.

Save the rest of your money towards one fo the many BIG front brake kits, or suspension goodies....

I do think that this is as big as a brake I am going to need because I don't think my car will be anyfaster then once it is tuned. So I don't think I will realy need a huge brake kit. But thanks for the suggestion.

Ah, well I am thinking...I found on subaruparts.com for 630 or somthing..I forgot the exact number they sell 4 pot fronts with all the nessary items it looks. Now since I will need rex rotors because I don't think I have the same rotors and my rs rotors are hurting. (pulling hard to the elft when I hit the brakes now .

I was thinking mabye I should look at rotors from an aftermarket company and get slotted? (I live in chicago and I heard drilled is not a good think with salt and snow) this might put me a few bucks over budget but I think I can get away with it because I am getting a deal on a semi expensive part. What do you guys think about that? Also stainless steel lines all around? recomended or old lines? Again...thanks alot for all your suggestions.

Doc,

To get better stops and less fade you need larger rotors.

For the rear, the big thing on the rears is not to lock-up. If the rears already lock up easily and you upgrade the rear brakes you must find a way for the rear TIRES to do more work.

4 pot full kit at Exeter Subaru $699.
Motul 600 brake fluid about $12 a 1/2 litre
You will easily outbrake a stock WRX on the track with this setup on an old school RS (did this in the instructor group at NHIS to see the difference) and then of course the WRX will pull away in the straights.

You won't need to bleed fluid every track day and you won't boil it.

Kit comes with everything you really need. Includes the antisqueel clips and guys who are an 800 tel # away to help with install questions (been there, done that). Comes with WRX rotors. Slotted ones are available for the fashion consious who don't really care about throwing away $$ for nothing.

They also have a guy working there with a turbo 2.5RS with this setup.
