Power Stop Big Brake Kit - Not for Track USE or for HEAVY Foot (ME)

[irondoor19]

OK:
So i purchased a Power Stop Brake kit, and after about 4000 Miles and 1 Track Day

Here are the Results:  I wasted the Front Rotors and Pads after 10 Laps (at Mid Ohio)

Ran off the BIG back strait at about 70 MPH after 120 Plus, Because the petal went to the Floor

Did a bit of lawn mowing, and the car came out OK, Needless to say, I needed a change in underware

So the instructor laffed it off, PUT me in his race prepped 944, told me i did not need any brakes and

LATER i did 20 more laps, till i almost collected a few more cars in the rear at the same strait,  I WAS DONE



After the 80-100 MPH Flog home and a couple more miles, I heard the dreaded Grinding, Here is what was Left:

I would agree.  At best for some serious street use, maybe 1/4 runs.  Definitely not for the track.

 

[irondoor19]

Yea:

I did not do any research, Just got it done, and the result was i almost waded
it up.... Looking at the EBC Stage 4 as the next upgrade, that will hold me till 2016

I have the Stage 4 EBC brakes. They get even better when hot.

Holy crap!! I was totally going to do PowerStop + z17 brakes... I'm thinking twice now....

 

[peppelepugh]

WOW

I've got the stage 4 kit, so far no issues. But i haven't taken her to a track yet....

I don't track my car, though I would love to... But I am loving the Powerstop Kit for street driving. Night and day compared to the OEM!

I put on a set of Powerstop Z23 Evolution Sport carbon fiber-ceramic pads with drilled and slotted rotors a few months ago.  Generally easy street driving. I've been happy with performance but am now noticing a little more brake noise (more like a whirring) than stock. My thought was it might be the slots and holes but I guess if it doesn't get worse I'd say the trade off of slight noise for extra stopping power was worth it.

Remember we are trying to stop a 4200-4400lb pig.  I just changed my stock pads and rotors and was surprised how fried they were, and I only did 1/4 mile runs.  Mike (BPD) spent the money and did a Wilwood brake upgrade.  I think that is the actual and only way to go it you want to road course these cars.  I'm pretty sure he has 15 in rotors upfront now with 6 piston calipers adn '13+ brake booster and master cylinder retro fit.

"EBC Stage 4 Kit on the way for the front",
Will NOT Do any track days, until we test @ 1/4 Mile
yikes that was close, Yes it is a Big Fat Pig

All correct info, 'cept for the 6 piston calipers.

Wilwood only makes them in a 4 piston setup for both the front and rear for the SHO.

I did upgrade to the "Poly Matrix E" Race Pad(s), as well as the "Titanium Heat Shields".

The 15" cross drilled and slotted rotor was a new (& recent) upgrade being offered, which increases the rotor size and thickness, versus the standard 14.25" offering.

I plan on doing this exact same set up on the rear, most likely purchasing middle of (this) August, and installing by end of August assuming a 2 week turn around on assembly and shipping.

Next to the newly built race motor, and then the tuning to go along with it, this Wilwood Big Brake Upgrade is among my Top 3 "Must Have's".

honestly i think the brake held up very well.. 10 laps plus your normal driving. YES the rotors got hot, but the holes don't appear to be cracked out you didn't mention warped pulsing brake feel? 10 laps on STREET pads with our big fast heavy car.. Im actually impressed.

though if your wipping out brakes on the 944 im thinking some change of driving might need to be in order or shorter stints to let things cool off between run.
Didnt the car talk back to you give you some hint the brake where going?

If you DD your car and only do 1/4 runs i think for the price these seem to be a good deal. For actual track day i would at least get EBC or project Mu pads and decent rotor. If you these rotor felt ok still there price would make them good track day use still.

I have purposly destoryed brakes before it takes a lot of heat. I mean making them glowing RED hot heat. which looks really cool at night btw.

Sounds like you had fun except for the burned up pads and most likely boiled brake fluid in your calipers contributing to your pedal to the floor experience.

Agree with Panther427, rotors don't look too bad and as long as they are not cracking or warped they held up pretty well.

Before you do another track day I would see if you can find a better "track"pad that can take the heat, flush your brake fluid and replace with a fluid with a higher boiling point.  Additionally you can look into making brake cooling ducts to help cool them down.

 

[irondoor19]

Yes:

We did a full Flush with Motul RBF 600, the week before i went to the track

The only Notice i got was when the Petal went to the Floor on lap 10....And i was mowing Grass

and afterword the other guy(s) on the track behind me said they Could smell the pads cooking

Ha..

This was my initial thought. But, Motul 600 is good stuff. 600 degree boiling point!

Wowzers, such a gargantuan car really is a burden on brake systems, when stretched to the limits.

Mogul 600 is good stuff but IIRC it does age on the quicker side.. How old was it?

 

[r1crusher]

I have done track days on my race bike at Mid-O and stabbing the binders off that long back straight from 150mph+ on a race bike can be hairy.  But doing it in a SHO...I'd need to change my panties and have my entire interior professionally cleaned if that happened to me.

Be grateful you only did a little grass mowing instead of some major landscaping.    "China beach" as it's referred to at the bottom of the end on that straight can swallow up cars whole.  If you're ever been to Mid-O you know what I'm talkin' about, there's a hell of a drop off.

I realize I'm a newb and my 2¢ holds very little credence, however, I'd tend to agree with Panther. Also, those pads are destructive, yes, but they are NO WHERE near as bad as I've seen after some very hot HPDE laps and lesser pads. "Worst I've ever seen"???? I'm a simple shade tree mechanic for friends and family (and friends of both) and I've seen pad BACKS worn near paper thin. Image below, just for reference, on some "bad" pad wear from a Lemons race. (Not mine)

I have an ecoboost explorer and  burned through all powerstop stop tech etc currently running ebc stage 9 and orange stuff pads stops very well i roasted 4 sets of front rotors in 50k miles
