brakes. pad/rotor advice. want to go slotted/zinc washed

well since adding any decent amount of power to this car costs almost 3k im going to just do rims and brakes.

going to paint calipers blue, get a slotted zinc washed rotor and wheels......than call it a day.


any advice....?? how are the ECS rotors..??

I had hawk HPS pads on other cars and loved them. was leaning towards them already but want to hear your guys take on it.

I just wanted to suggest not going with slotted rotors unless you track your car, they will wear your pads down much quicker. If looking to keep brakes cooler just go with crossdrilled, wont put as much wear on your pads. And I have heard good thing about the ECS rotors.

Cross drilled has the micro cracking issues. Not too interested in those.

Pads, who cares, ill just get 2 sets. lol

Why would having a 328 vs a 335 result in different recommendations on brands for these components?

And, we need to know your intended purpose- tracking? daily driving only? show queen?

Then we can give you useful advice.

Wouldn't be *that* hard to find a pad that works well for both DD and autox. Something that also works well for "road racing" (and by that I'm assuming you meand HPDE and not actual road racing), that's a bit trickier. I happen to run pads that are probably too aggressive for the street for most, in that they squeal when you aren't romping on them. They are Racingbrake XT910s and I love them.

For your application, there are a lot of options out there: EBC, Hawk (HPS/HP+), Racingbrake ET800, Project Mu B force or HC800, Pagid, Carbotech etc. The key is to choose something with a wide operating range (0 to 800 degrees C.. higher than that is track pad territory).

Rotors are a personal preference but I'd recommend staying away from cross-drilled if you plan to spend any time on a track, simply because they crack sooner than blanks or slotted. I run slotted ECS geomets and I'm happy with them.

Slotted makes some noise and drilled can crack. They are not very good choices unless you only care about the look. I have also seen reports of aftermarket rotors warping. That's why I stick with OEM blanks. I'm using Hawk HPS because of the dust from OEM pads. Great pads IMO.

Saying slotted rotors are for looks is a bit disingenuous... They help even pad wear, and promote deglazing. The downside is increased wear and noise, as you did indicate.

already stated not going drilled because of cracking issues.

I have SS lines. Keep in mind that replacing the mid lines that join the chassis to the subframe is a beyotch (I've done it, and it's not fun). Do it if you want a slightly firmer pedal, but not if you're expecting a world of difference. You get more bang for your buck by simply bleeding and using much better pads.

The Geomets are great.

Honestly I have no experience with Hawk personally so I can't say anything good or bad about them. I've *heard* that HPS is a good street pad but not trackable at all (I think the recommendation is to go HP+ for a hybrid pad if you want Hawk). Their Blue and DTC60/70 pads are well known for serious track use, but there are reports of corrosive dust so I've generally stayed away (but I don't think that applies to the street compounds).

I am however a fan of Racingbrake's compounds so far. Will be trying out my XT910's on the track soon so I'll know if I hit the sweet spot in hybrid compounds for me. The ET800's I ran on my last car were awesome on the street but overheated on the track, so I upgraded.

the HP+ is like what you have. or what you describe you have, unless you hammer them they squeak bad. I had them on my camaro and ditched them for HPS's after 500 miles.


i was only doing 1/4 trips and auto x at the time so i had no need for them and the noise got annoying.
