Stoptech BIG brake kit!!!!

[tsirider13]

Hey guys, I order a big brake kit from stoptech and it just arrive, This thing is just huge.
Anyways it will go on the car tomorrow (Just in time to put it away), But i have a question i was reading that the rear brembos from an evo would fit our cars?(2G)

Is that true?
Here are some pics, I will post more pics of the install tomorrow.

Rear EVO Brembo's bolt on, and you use the EVO rotors as well, your DSM brake lines will work.

Kahl23 is correct, Stoptech designs their systems to work with the stock rear brakes. By throwing on the EVO rears you WILL have more rear bias. If you find you still need more rear bias with the Stoptech kit (I doubt it) you could always do the EVO swap and a proportioning valve. Personally, after I installed my Stoptech's, I experimented with different brake compounds front vs. rear to compensate for any bias disruption/adjustment.

Rear brembo brakes bolt right up and will work weith your lines... Here is a picture of my reear, and I use it with a wilwood front setup(13x1.1)

Well i went out to the garage today and i got to do some work.

I removed the cobra brake kit that i had on the front, but i did not got a chance to bolt on the new one, Anyways here are some pics.

And i though that the cobras were big.

P.S.
Here is what the old big brake kit was:
the old brake set up was: Mustang Cobra caliper and rotors (13") SS lines for a 2G of course and a special braket that is being sold by ziggy at RTM Racing .
The brakect it self comes with bolts, spacers and centric hub rings.
Note:Even if you have a 1g you will need 2g lines.

That is one good looking brake kit. I like this kit because it has been proven to work REALLY well. But, for when I do a big brake upgrade, I'd want it to be all four. That way there is no weak point. I was really thinking of doing the Evo conversion, but those knuckles are so damn expensive.

What kind of pads are you going to be running? Does StopTech make different compounds for them?

 

[tsirider13]

Yes they do, they recomended AXXIS ultimate.
I will probably grab a set of those and a set of blue 9012's and see wher it takes me.

2Gs are 3000+ lbs. Skinny 10 inch rotors don't cut it for everyone. My experience with the stock brakes was one hard stop from 70-0 would warp a set of rotors on the street. Not to mention I never liked the factory calipers, they always seemed to pull unevenly under braking. That alone was unacceptable for me so I upgraded to the Baer track kit. It was only a couple hundred more than new factory rotors and quality pads and the rotors last much longer, especially if they only see street use.

Btw, my first mod to my car 5+ years ago was the bbk and I still love the upgrade. OP, nice setup; they'll perform wonderfully and look great to boot!

That's funny, I put over 600 whp and I'm on the stock dual piston brakes and I DON'T have any problems stopping whereas you my friend are probably putting somewhere around 300-350 whp but your having problems stopping. I wonder why that maybe...

It sounds to me like you're a drag racer. If you were a road racer, you'd be having issues stopping a 600whp car on the road course consistently. And even if you don't have issues stopping, your lap times are likely suffering due to your smaller brakes. You might have noticed that this forum is for road racers and autocrossers. Most of us use our brakes in more extreme situations than drag racers. To call it a "ricey" mod in this forum is like calling a big turbo a "ricey" mod in the drag strip forum. Who actually needs a bigger turbo anyway?

It's about building your car up for what it will be used for. In this forum big brake kits are important for improved lap times. I could understand if you tried to make that point in another forum, but not here. Functional mods that increase track performance takes priority in here, and big power typically takes a back seat to braking and handling (or at least it should).

 

[Ludachris]

This is the Road Course/Autocross forum. Who cares about what is necessary on the street? Wrong forum.

 

[Ludachris]

There are only 2 big brake kits I'd really consider for a DSM - TCE (Wilwood hardware) and Stoptech. I love the countless options available from TCE - they're the only company who makes more than one option for our cars. You can get just about any type of custom setup you want for your needs at several price points. And Stoptech is Stoptech. You can't really say anything bad about them, except maybe that they don't always fit perfectly and they're more expensive.

That's my preference.

 

[tsirider13]

When are you going to put them on? Everybody is getting impatient. Toronto is pretty far but I guess I could take a couple pf days off of work to help ya out. China Town in Toronto has the best Asian food!

I know, i will put them on Saturday.
I work 12 hours shifts, So i dont really want to work on the car when i get back home .
There is a few other things that have to go in it, just have no time.
Saturday afternoon i will post pics of them on the car and of my new track wheels.

Stoptech's rock. You won't be disappointed. I have a set and also have evo brembos for the rear. Great setup.

My fronts. Yes, I know only three lug nuts are on. I was just making sure the wheels would clear the brakes.

Bickering, bitching, rice-calling, arguments, mis-information and opinions have been deleted from this thread. Save it for the Hangout.

Stay on-topic. Don't call another's desires "rice" or other desultory terms.

 

[D_Eclipse9916]

Wow I love that color scheme n those stoptechs with the rays wheels. Hawt!

Also something kind of related, I have the wilwood 13x1.1 setup with the evo rears and just put on the rear evos and my master cylinder took a shit. Anybody have similiar results? I bled the shit out of em thinking it was that but after bleeding em a billion times it still takes a few pumps of the pedal to build up adequate pressure.

I have "heard" of people using larger master cylinders in other cars, are we getting to the point of maybe needing to be able to use a larger piston in the master cylinder to deal with the increased piston area of both front and rear setups?

 

[Ludachris]

Again, this is the Road Racing forum. Stay on topic. Whether or not a mod is "necessary" for the street is not relevant in this thread (and in most cases. this forum).

 

[slipstream808]

So, you're Stoptech's are front only, right?

I've been debating them but I wish they offered something for the rear brakes. If you've had a chance, how do they feel compared to before?

 

[drivemusicnow]

The really isn't much of a reason to upgrade the rears. The more significant your front brakes are, the less you can effectively use the rears.

Think about it this way, brake effectiveness is a function of grip. Grip is a function of weight pressing the tire to the ground, and the tires adhesion properties. When you upgrade the front brakes you're increasing weight transfer to the front (because you're stopping harder) and effectively reducing the rear braking ability. If you can lock up the rear brakes with the stock rear calipers, then you don't need bigger rear brakes.

The other part of this is that you need an ability to adjust brake bias front to rear, because brake bias needs to be a function of grip which means you need to change it depending on tires/weather/ etc.

One of the best mods I ever did to my car was the AEM big brake kit and change to Porterfield R4S pads. Although only a modest jump in size (meant to be used with stock wheels and calipers) the improvement in braking performance was profound.

I got the front and rear set. IMO it's a good idea to get a front/rear set that were designed to work together, unless you are really devoted and want to play around with front/rear bias.

Sport Compact Car had a pretty good test and write-up on big brake kits and brake bias in the October 2007 issue if anyone's interested.

Here's a pic of my fronts. A little weathered but they work great.

 

[bmoha2]

Too bad they don' make the big brake kit anymore

 

[aves911]

Since some people brought up the Evo rears, are the rear rotors from those cars vented like the early 95's?

yes

 

[tsirider13]

I was told by stoptech not to upgrade the back, just to play with pad compounds.
They told me that the front kit was engeenier to work with the stock rear set up.

The really isn't much of a reason to upgrade the rears. The more significant your front brakes are, the less you can effectively use the rears.

Think about it this way, brake effectiveness is a function of grip. Grip is a function of weight pressing the tire to the ground, and the tires adhesion properties. When you upgrade the front brakes you're increasing weight transfer to the front (because you're stopping harder) and effectively reducing the rear braking ability.

I don't have Stoptechs, so please correct me if I'm wrong. Fundamentally, I agree with what you're saying about weight transfer, it's simply a matter of physics, but these stoptechs are designed to work with a stock suspension car.

They (stoptech) told me that the front kit was engeenier to work with the stock rear set up.

The weight transfer under braking (requiring less rear braking force) is reduced as the suspension is modified to reduce fore and aft movement. As this happens, the rear brakes become more involved. How much so? I don't know.

I do know I'd rather use all four tires (as much as possible) to slow the car as fast as possible. I'd like to maximize the braking assistance from the rear brakes as much as possible without crossing the line of course. :enters corner backwards...

It's just my personal theory about my own car, but I believe installing the evo brake setup, which shifts bias rearwards will improve this balance. Unfortunately, I have yet to test this out.

Thoughts?

If you can lock up the rear brakes with the stock rear calipers, then you don't need bigger rear brakes.

Adding "on the last hot lap" in there would make it more accurate.

 

[tsirider13]

I see what you're saying and think you are right, But I dont know how acurate that asumption would be.........
