So I am a noob to the Subie group (a recent Honda convert, and kinda a Vintage Vette Guy). I am not yet familiar with how many different setups the Fozies come with. Does the FXT have the same brakes as the 2.5X? Do WRX's share same power brake boosters with other Subie models?

Ok. I have sorted through tons of threads on brake upgrades, with this and that in them, but no for sure answer, So...

I have a 2010 base 2.5X with with the steel wheels. What are my options for installing larger (possibly WRX) front rotors?

1. What will bolt up?
2. Do I need new brackets for the calipers?
3. What calipers (ie what car do I pull them from?) am I going to need to look for?
4. What size rotors and what Subie are native to?
5. Are they going to be compatible with current brake hose setup?
6. Are they going to work with the current brake booster/master cylinder?

I'd start off with better pads and fluid and maybe SS lines before anything. The SH Foresters have the same brakes as the SG Foresters, which is the same as the WRX (not including the 06/07 which had 4/2 pots).

Do you have drums or discs in the rear?

+1 on better pads first. Unless you're taking your car to the track save your money.

 

[justinw2116]

Definitely want new calipers...

I understand getting better pads and rotors, but...

I definitely want larger calipers, it allows me so many more options, down the road. And I would rather not but better stuff for my existing brakes, because I know I will just end up upgrading the calipers later.

Any reason why you want bigger?

You can go with WRX 4 pots upfront, and those are an easy swap and look good. They bolt right up and use the same front rotors you already have which are 294mm.

If you want bigger rotors, you can go with LGT calipers/rotors (316mm) or with Brembos with 04 STi rotors (326mm?).

For the back, you can do the H6 upgrade, which increases the rotors to a vented 290x18mm rotor which is a big step up over the stock 266x10 stock rotor. My sizes might be off a slight bit (going off the top of my head).

For th erear yo ucan also do WRX 2 pots or STi Brembos, but those both need adapters to fit the calipers to your car. You can use the LGT rear calipers/rotors and those will bolt right up, but are not as nice looking.

Not rotors, pads. Until you upgrade to two piece rotors you're not going to get an improvement.

Larger calipers offer better fade resistance for track use. What other options are you talking about?

From what year WRX, for the 4 pots up front?

I'd skip the 4-pots and go for the Brembos off an STi. I can't justify the cost of doing this on my car as I can lock up the stock brakes with Hawk pads, but to each his own.

Same here. I'm pretty sure Stan and I both put down a ton more power than the OP and we both are pretty happy with the stock calipers/Hawk pads.
