    Its time to get new pads and I want front slotted rotors. Just want to know what you guys think. I have a 2005 WRX.

    What brake pads should I go with? What kind of front slotted rotors should I go with?

    can't go wrong with brembo or stoptech... what results are you looking to acheive? have you considered putting larger rotors/calipers on?

    i think you can get the stock 06+ 4-pots/calipers for a decent price.

    pEd This ain't no Piccadilly!

    HP+ are nice pads. No idea on slotted rotors though.

    Monk has a point, any thought on upgading to the red/black Suby 4-pots?

    I have seen the HP+ eat holes through the brembos. If you decide to get the HP+ then you should definitely get some sort of vented rotor. Personally, I would stick with a stock sized rotor that is slotted and go with the HPS. Unless you are doing track days, the HP+ are too aggressive and will be very noisy at every stop light. Sticking with the stock sized rotor will keep your options open later on for different wheels if you decide to race. It will allow you to get a 16x8, which has more tire options than the 17x8. If you haven't already, I would also replace your lines. I went with the Goodridges and it has gotten rid of almost all of the sloppiness of the pedal when braking hard.

    i went with a suby dude package and was very pleased with the results..here is one of their packages that comes with CT721 (2002 WRX) or CT929 (2003-2005 WRX) Front Bobcat Pads, DBA 4,000 Series Front Slotted Rotors, 2 bottles of RBF 600 Fluid

    Stage 1.2 Adds DBA Brake rotors to help cut and de-gas your Bobcat street pads! Keeping temperatures even cooler which results in less brake fade!

    Tom really hit the nail on the head here. For a WRX, HPS pads, stainless lines, and fresh fluid is all you need. I couldn't believe how much difference this made. It's everything I was looking for and then some. I'm using my stock rotors too. My brakes went from suck to impressive for less than $300. Changing to a 4/6/8/whatever pot caliper isn't going to make ANY difference over the above setup. Your tires are going to skid before you'll notice any difference. It's all about traction and I can overpower 245/45 Hankooks with the above setup. :naughty: IMHO, massive brake systems are for bling.

    True, HPS isn't for track days, but to prevent melting your hubs you should do a lot of research on brake pads, compounds, and heat range before you hit the track. The temperature ranges of track pads on the track are high enough to eat your rotors and melt your hubs. Track days are for the rich kids... :(

    I'm sure adding DBA 4,000s to the mix will help, but you'll have to weigh the cost/benefit. I don't know what your budget looks like.

    *** anyone know if the '05 will accept the H6 upgrade? I didn't suggest it b/c I'm not sure if it's applicable...***

    I disagree. I've been using HP+ pads for many many years with no issues on multiple cars. They are fine for a daily pad and track/ auto-x use. Stop on a dime everytime and no problems with rotors. I will never use anything less. They have never been noisey at every stop light. The only time they "sing" is when I drag my foot on the brakes. If you brake normal, they are fine....for me.

    ^ +1 i've ran hp+ on 04 wrx stock rotors (hard) and it was fine for the 10k that they were on there for.

    and I have to disagree about the larger brake systems being for "bling"... the stock wrx rotors and calipers (pads more specifically) have a hard time being consistent with the heat generated by road course driving. that's with superblue fluid and hp+ pads on them... they still fade fast.

    now, i haven't taken the sti out to tgp yet, but i do remember how the brakes on other sti's i rode in felt solid into every turn.

    granted, you're only going to stop as fast as the rubber can hold traction, but you're also only going to stop consistently as well as your rotors and pads (and fluids) can take the heat. larger rotors and calipers will deal with more heat simply because of increased surface area.

    but like i said before, it's about the application he's after. if he doesn't do road course, then a larger setup is probably not an avenue worth pursuing.

    I totally agree, but that wasn't my point. HP+ pads and fluid aren't what I had in mind. HP+ is almost a street pad, and that's why it faded and didn't kill your rotors. With race only pads (~1400 degree), stainless lines, and FRESH fluid you wouldn't have had a problem with consistency, but you would with rotor wear and hub life. Real race pads can take MASSIVE amounts of heat, and will not fade.

    True, a caliper that can apply more friction (4/6/8 pot), higher temp pads, AND larger sized rotors to help dissipate heat all used together is the only answer for a real track car. STi brakes have all three of these components. That's why I said it's for the big boys. If the car is not on the track there's no point- hence the bling factor.

    Think about this, Corvette ZO6s have only two pot front calipers and they haul ass... Simply adding pots to a caliper isn't going to change the friction component of braking. The 4 pot 2 pot upgrade isn't going to help. It uses the same sized rotors and pads.

    A slotted rotor may help, but with a modern vented rotor it doesn't do much unless it's raining.

    And lets not forget about tires. if you're running stock tires this is pissing in the wind.

    Update, yes the HP+ pads squeel more than I noticed on my daily commute. I guess I've learned to ignore it. :D

    What is the best place to buy some Hawk HPS pads for a 05 wrx?

    230ish for the dba 4000's here. http://www.autoanything.com/brakes/61A3529A0A0.aspx

    I think that might be cheaper than the suby-dude package unless motul brake fluid and pads cost 200.

    Are the CARBOTECH Bobcat brake pads better than the hawk hps pads?
