Wrap the ball joint and tie rod ends w/ header wrap or something to prevent melting

Lastly - check your bank account - make sure it is well stocked.
Sound advice. Track days can get expensive very quickly. When you factor in the cost of the event, fuel, tire wear, brake wear, and general wear and tear on the car you can spend anywhere between $300 and $1000 for a single day at the track. A couple local friends stopped running at one of our local tracks because one day at the track toasted a set of front brake pads. One of them was using Carbotech XP8's the other had Pagid RS19's which are supposed to be an endurance pad (probably better when not on a 3000lb car). Not cheap pads to replace.

Of course everything gets really expensive when you don't spend money on your brakes and they lead to a failure and you end up wrecking the car.

I'm looking for a pair or set of good slotted rotors and pads (DBA rotors). I need for the rear but was thinking about doing all 4.

What do you reccommend?

Sorry. It's cobb stage 2 daily d. So just street use. Maybe once in a blue moon track use. I do plan on doin turbo swap and more work on it as soon as i pick up a new dd. Wanted to make sure brakes and suspension work is done first though.

The rotors are starting to get that lip on them and its time to change the rear pads so i figured to change to slotted rotters and possibly new stainless brake lines.

Shipping zip is 22030.

read the sticky about slotted/drilled rotors. If the rotors are toast, get some centric disc's from kns and some street pads like the hawk hps, or some ceramic pad. Theres no point in spending 1k on disc's and pads for a 250hp dd that will never see a track.

Oh no i didn't want to spend that much. I honestly found some packages with dba slotted rotters for like 500 bucks with pads included. Just wondering if anyone knows or is having a current sale on anything that i have not come across already.

Hey guys I am looking for some brakes and rotors for my 2007 WRX I am looking to spend no more than $500-$550. I drive pretty spiritedly so I am looking something that is better than stock. Looking for slotted rotors and decent cold bite without a lot of fade.

I am currently looking at this "kit" http://www.knsbrakes.com/carItemDeta...&item_id=37621 I really don't know how I feel about a kit but sounds good actually. I'd like to keep brake dust down because I am literally cleaning my wheels a few times a week. I have the stock rims and if I don't it looks like they're gunmetal. Thoughts? ideas?

Call Ken @ kns. You dont need slotted disks. Choose the propper pad for your use and some centric disc if your oems are toast.

Default Rear caliper mounting bolt size

I'm trying to replace the pads and rotors on my '05 Impreza Outback Sport. I tried doing the rears last night and could not loosen the mounting bolts that hold the caliper body to the rest of the wheel assembly. It's very, very rusty down there, and I'm afraid of breaking the rusty bolts without having the correct size replacement bolt. The bolt head is 14mm, but I don't know the thread size and overall length of these bolts. Are both mounting bolts the same length? Are the front bolts the same as the rear? I'll be doing the fronts when the rears are done.

Thanks for helping the new guy!

Did you ever solve this problem? Did you try a penetrating lubricant like PB Blaster to help break the bolts free?

This is very helpful information, I never really understood how "brakes do not stop your car, tires do." Now I do, my question now is do I spend $540 on stoptechs stage 2 sport kit for 2012 WRX sedan and grab some nice tires? or, do i spend 1,000 on really nice tires and just upgrade the pads?

Originally, I wanted to do brakes and calipers and rotors and the whole nine simply because my brakes are mini IMO but, now im wondering if it is even going to benefit me in anyway.

My goals are: better stopping power (trust in my brakes). Personally the brakes on the WRX are way under powered but I guess it is also the tires.

So, big money tires? and upgraded pads and lines?

or stoptech stage 2 package and better then OEM tires?

Which will give me the better performance application and confidence?

Better pads that match your driving and high temp fluid if you brake hard a lot bwill help the stock brakes - and lines/MC brace may firm the pedal a bit.

Depends on how hard you want to go at it. Better tires are always worth it - but grippy tires and pads will wear faster.

That's because it's a silly, overstated way to make a point. If you take the tires off the car and apply the brakes it will still stop, but if you take the brakes off it will not, so kind of silly. The point is is that everything happens through the tires since they are the only point of contact with the road. The grippier the tires the shorter the stopping distances, but also, the more friction and heat the brake pads can generate, and the rotors can subsequently dissipate, the shorter the braking distances will be. So they always work in tandem.

Upgrading to a good street pad and to decent tires will make a big difference in braking feel and performance.

My mechanic just told me I should start looking into getting new brake pads. He said my
Rotors are still good. My car is a DD so only looking mainly for street use with some aggressive sprinting drives of course. What brake pad do you guys recommend? I read the article and from
What I understand it looks like ceramic pads are the way to go? My oem gathers up way to much dust which bothers me. So a pad low in dust and as far as noise level. Nothing to annoying as I drive everyday

Like with tires, one brake pad can't do everything. With that said, ceramics are probably best for you. Low dust, low noise, less bite than StopTechs or HPS pads which are more for 'street performance' and have more dust.

Re-machine the rotors with the new pads. Or get new ones if you don't want a rusty look. Centric has blanks that are cost effective at $40 a pop.

I've stopped turning existing rotors and just replace them. My experience has been that machined rotors warp quickly because they don't have as much metal mass to dissipate the heat.

First, understand that not all brake pads are created equal and the different types serve different purposes. Second, realize that you can't get one pad to do everything. Those good for street use are useless on the race track. Those designed for the race track don't generally work well on the street.


What are you doing with the car which is causing the brakes to fade? Spirited driving? Track day? Autocross? You took the first step by flushing the system and filling with a higher temp, track oriented fluid. The next step is choosing a proper pad for your intended use. Autozone/Napa pads are generally cheap crap intended for city stop-and-go driving. You need to step up a bit to find something that'll survive spirited back roads, and it's quite the jump to a true track pad.

The problem with cheap "street" pads is the temperature range. They are designed to work at low temps and do not have a very broad range. If you get them hot they begin to fade very quickly. If you get them too hot they can melt and fall apart.

Stoptech Street Performance pads are a rather fantastic value for all-around use. They work at colder temps which makes them good for daily driving in nearly any conditions, but they also survive at moderately high temps. You could use them for spirited driving and autocross. I would not push them at the race track in a heavier car (like a Subaru). I think you'll still build too much heat and they'll fade.

For full-bore track use you can look at the Carbotech XP8. They are designed to work at higher temperatures and are at home on a race track. As such, they do not work well at lower temps. Using these in a cold winter might feel like you have no brakes as the material in the pad MUST be warm to function best. You'll find that track pads are generally more expensive and due to track use and repeated hard braking events they don't last very long. They'll still outlast any "street" oriented pad ever will on a race track.
