AP, Brembo or StopTech?

[CarbonFoot]

I agree that pad changes with the Brembo's are harder than they should be. Especially when you're trying to protect the caliper finish while you have them hanging or supported off the mounting bracket. Wish they had the removable bridge like the latest models have, but there's no disputing that they're great brakes otherwise.

I went with Stoptech for the ease of changing pads.

StopTech with Apex wheels is a very popular combo at track events.

I think it'll be a good combo. I'm not tracking that much and wouldn't be changing pads at a paddock so pad change isn't a huge concern. My biggest is, like I mentioned earlier, disc/pad wear and quality for long term daily use.

Replacement parts are WAY cheaper for ST too. The standard Streetsport pads work pretty well on the track too if you do a little more conservative braking. They also dust MUCH less than stock pads and have very good initial bite. And did I mention they only cost around $100/set?!!

chose stoptech on my m3 because replacement parts like rotors are cheaper and easier to find compared to brembo. brake pad shape of stoptechs are also very easily available in many different compounds/brands.

i bought the ST60 front calipers with 380mm rotors and ST40 rear calipers. the entire kit cost me about 1.5k less than the equivalent 380mm brembo kit.

pad changes on the Brembo's is way overrated. takes maybe an extra 3-5 minutes tops. that's a minimal difference when you consider the other hassle of pad swaps (removing the wheels).

This is a great point. StopTechs allow you to experiment with so many different pad brands and compounds.

I have the ST60 380mm front and ST40 355mm rear StopTech kit and love them. I put them on when the car had about 1100 miles on the clock, right before my first track event with it.

I've managed to make HPDE instructors nauseated with my threshold braking. (Not sure if that's a good thing or a bad thing.)

Same. Love my ST60's. Easy to change pads and the brakes work very well and don't overheat on track.

It is not about the time.

Why do you want to get rid of the APs??

I've had both StopTech and Brembo on my car. I only have anecdotal experience with AP, so I will refrain from discussing it.

I think StopTech definitely offers the best value. Its bridge design is excellent for pad changes, but it could also be an issue if the fitment is not 100%. I've worked on cars where the bridge required some slight modifications. There are also other minor fitment issues I've experienced on StopTech, but StopTech in all cases responded and resolved these issues in a timely manner.

From my chat with a StopTech executive, they have been bringing in-house a lot of manufacturing processes that were previously outsourced. I think this is probably the source of some of their "hiccups."

My StopTech kit was on the track extensively and it held up extremely well. It also found a great new owner

Brembo, IMO, offers the best quality. In each Brembo box you will find a checklist where a human being physically verified that all the parts are correct based on the part numbers and present before shipment. I never saw this type of list from StopTech.

Operating cost... Brembo has always told me that their rotor, which costs more than StopTech, will last longer than StopTech. Unfortunately I don't have the time nor resources to verify this claim.

Pads... StopTech certainly has a wider (and cheaper) selection of brake pads. Brembo's aftermarket pads are more limited and more expensive (due to larger size and less production volume). Besides, what else do you need besides Pagid Yellows

Thanks as usual for your real-world feedback. Were there any differences in overall performance and/or pedal feel between the stoptech and brembos?
ps, my Stoptech's have held up very well in my extensive track use.

Thanks for the inputs fella's. Interesting to read your experiances. I like my AP's but I'm thinking of going with the StopTechs for the $ value and Pad choices.

Has anyone ever experianced after consistant hard use any disc warping from any of the kits? Shortend pad life, other problems?

How can you come out ahead $-wise if by trading your AP's for StopTech or other kit? Also, AP is at the same quality level as Brembo (meaning better than StopTech).

Brembo and AP have the best disc materials (along with Alcon). StopTech and others are a step down from those three. This info is from one of the main racing systems suppliers/constructors in the US. There is a reason for the price difference between the various kits; you get what you pay for.

Having a hard time understanding your reasoning ??? Stick with the APs!

uh, interesting. Seems more people picked Stoptech over AP and although I've only owned the AP's BBK so far, I think their very strong exept that I already went through one set of front rotors that warped within less than 3,000 miles of just street use and no track use. Run-out was far beyond limits.

Bed in was done per the instructions along with cooling. Plus I had to get the calipers/rear hats repainted by IND because of wheel cleaners completely etched the paint, which really ment the paint of the calipers did not meet up to general cleaning. Perhaps my fault, but so far I have not had favorable results. But to be honest, my OEM BMW brakes withstood numberous track days in England and three weekends at Nurburgring and the result was just some rough brake feel from pad transfer that eventualy went away and the discs never, ever cracked or warped. I installed this kit and its been a f*&kng headache and I haven't even put as much strain as a single track day on this kit and already gone through two discs. How does one explain that???

I didn't want to post anything negative yet but I guess I'm experiancing stuff others have too with various kits. I don't know?

So my reasoning is that I want brakes that won't warp under normal use, also that the finish won't eventualy peel off with wear as now my calipers are painted. Although IND did an awesome job IMO. But in the end so far, my AP BBK has cost me as much as a damn supercharger. That does not make me too happy.

Came across this today. Any one have experiance with URGE designs rotors?

I would say that the overall feel is quite similar. And my seat of the pants feel is that the Brembos gave me more control and tend to lock up less than StopTech. But it could just be that the pad materials are different.

I know many StopTech and Brembo owners for the E9X M3 who track regularly and non had such issues.
