Question Subaru 4 pot calipers, good investment?

Thinking about getting them & want to know, form those of you who have them, if they are worth the money or if a good set of pads and sloted roters are just as good?

It would also depend on what 4 pots your looking at. If you want just the STI 4 pots then I can tell you that it will fix the mushy pedal feel in the RS. Of course if your a MY99 and up owner that means changing the master cylinder and brake booster to a single stage. You can get alot of different 4 pots. Brembo, Tarox, STI, Baer, APC, and a few others. 4 pots won't require you to go to 17in rims also. The STI brakes aren't as expensive as what I thought they would be. I got some off of the Scoobynet. You can usually find them on there for 300-400 UK Pounds. If your just going to use it on the street then you may want to just change the pads or upgrade your rotors. The 4 pots themselves aren't probably going to be required. SS brake lines, slotted rotors and the booster will do just about everything that you need your brakes to do. One of the only reasons I got the STI brakes was because I found some brand new STI brakes and the owner wanted 350 Pounds for them. If you can find a deal then I can see getting them for street use or show. For now swap out your rotors and pads for better ones. Rallispec sells the Goodridge SS brake lines for $125. KVR sells the slotted rotors, although I forgot how much they are for the stock size.

The STi 4-pots are more then sufficient for hard use on the street or short term track use (upgrade the pads for track). For continuous track use you are better off with something like the Brembo, AP or Alcon big brake kits.

The STi 4-pot kit comes with larger rotors (the larger rotors can handle greater head loads) but still fit under 16" wheels. AP and Brembo have kits available that will fit 16" wheels as well as larger 17" kits. The Prodrive Alcon kit will only fit under at least a 17" wheel.

We can supply the STi 4-pot kit for $950. We can also supply Brembo, AP, or Alcon kits (please call for pricing). Also, other upgrades you may want to consider are:
braided lines (we have Goodridge DOT approved kit for $115), single stage brake booster ($320 for MY98 and $420 for MY99-00), and Mintex competition pads (Mintex 1144 front set for $125

I tried mine (STI 4 Pod) out for the first time, after installing them yesterday, at an auto x today. ( see my post in the general section, under Team Suby kicks a$$ in TX AGAIN!!)
Depending on what you are going to use your car for..... will decide which is better. to me, it was a no brainer... spend the money on the brakes..
Here shortly cobb.com should have some pic's on their site comparing the two rotors and calipers side by side, as well as driving impressions......

All I can tell you is: BUY 'EM!!!

Cool

They are not just as good, and they can be much better...which brakes are you talking about? If you are upgrading, don't just buy some brake that fits. They should be lighter and have thicker rotors (to dissapate
the heat generated) and a greater brake surface. The brakes that come stock on "other than US cars" are also being upgraded by their owners. Brakes and brake kits are "happening" now.
I forgot to ask...what are you going to do
with the car? If you will require lots of heavy breaking from fast speeds upgrade the
brakes, if not, upgrade the pads.

Thank you for all the posts.

I am considering the STI 4 pot for Mtn driving and auto x. I am looking for quicker stoping from high speeds and less fade.

Andre, I've got comparison pics of the STi and <A HREF="http://members.home.net/gopspin/">standard rotors on my site.</A>

Feel free to steal any of the photos and put them on Cobb Tuning if that saves ya any effort. Just click on the "STi 4-pot Brake Install" link.

I agree with Rallispec & Andre's assessment: buy 'em. If the Alcons/Brembos were reasonably priced, they'd be a much better choice. $2k for 17" wheels & tires plus, what, $3-4k for the Alcons? OUCH!

Is this a must with STi calipers or just options for better brakes?

I thought you didn't have to change the master cylinder unless going to the single stage booster on the MY99 RS? What fluid are you guys running also? DOT 4?

Now I know the firmness is better, however, how is the stoping power?

I'm running Valvoline DOT 4 (I think some kind of formulated synthetic).
We had a fairly long course (71 + sec) that required a lot of hard braking, and I had no fade, and pretty good feel with my stock Master cylinder. I think brake feel is more a personal prefrance than anything else though. What may be perfect feel for me, might be horrible for someone else and visa versa.

Thumbs up

Stopping power with the STi units is fantastic. It's much easier to activate the ABS (i.e., reach the limit of the tire's adhesion) with them.

You do not need to use a single stage booster with them. It's just nicer if you do. MY98 single stage booster doesn't require a new master cylinder. MY99 does.

The Alcon/Brembo brakes offer far superior fade resistance, but at a commensurately superior price.

There are currently 4 sets of 4 Pot brakes on sale on the Scoobynet. There is even a set of brakes off of a 22B for sale for 400 Pounds. Just thought I would mention it. I also just posted the link to the EBC site that has info on it for helping you decide on what pads to run with your setup.

Cool

From what I saw in SCC's write-up of the 22B, the 22B's 4-pot calipers are exactly the same as the standard STi 4-pots.

Am I wrong? The only difference I see is that the calipers are red.

R Diamond, your right they are just red STI 4 pots. There is nothing special about them other then that people can say they have 22B brakes. I only posted it cause Alex was trying to get them and I thought others might want them. The brakes were the same price as any other 4 pot STI unit. There was however two guys selling their brand new STI brakes still in the boxes. They swapped in the Alcon kit and the cars never used the STI ones. Oh the reason why is the cars are new P1's and they got the Prodrive upgrade for the car. Good call on them not being special. Not many people would have notcied. Also if you look at pics of the 22B meet at Motorweek you'd notice that the brakes on the 22B looked tiny compared to Adam Blooms Alcon kit.

I have ex P1 brakes on my UK MY98 turbo. I am currently running standard pads and discs with DOT5.1 fluid and goodridge hoses. The brakes are much better than the standard 2 pots fitted to all UK cars up to MY99. You can still get them to fade though on really good twisty roads but, I guess twisty roads are not such a problem in the US

I don't know. I grew up outside of the Redwoods in northern CA. Now those are some interesting roads. Huge freakin redwood trees on one side and a 200ft drop off a cliff on the other. Now thats a motivational road for bad drivers. I think the northern CA guys should do a road trip out there. Alex can even go look at the old Russian fort from back when the Russians had settled the redwood area. Make it a weekend road trip and stop to fish along the way. That road will make you appreciate your upgraded brakes.
