Both Stoptech and Brembo for example, advertise BBK's for street and track use. http://www.brembo.com/en/car/sportin...braking-system http://stoptech.com/products/big-brake-kits/overview Quote:
^ Yes, and that's exactly why I wanted to follow-up on this, I was told the same thing- that a spring clip would be forthcoming for the rears...

Please don't misinterpret my posts here as being confrontational. I am delighted with the weight savings, performance, cost and ease of maintenance/replacement of your product...it is only lacking an anti-rattle spring clip for the rears. With a clip it would actually be perfectly usable for both street and track...not sure if your new website includes a disclaimer or not, but as an early adopter and someone who has already gone through four different BBK kits on the e92 platform, I can assure you I was unaware that this kit was designed for track use only. ...thank you for clarifying that this kit is not recommended for street use.

thats a huge bummer if they aren't going to come through with the rear clips. the clips would literally make this rear kit the perfect kit. i'm very happy with how quiet and unnoticeable the fronts are until i call upon them at the track.

Understood gents. I will bring the spring clip issue back up in our next product planning meeting. Thanks for the level-headed discussion and feedback. I know gathering customer feedback is how we can continually improve our product.

In summary, regardless of which brake kit you choose, you're ultimately assuming all risk and you're on your own. When you dig into the details, you'll find that's the case with pretty much all aftermarket parts in the USA. They're legally intended for off-road use only, and the buyer assumes all risk when installing them. The reason for that is our litigious society. Every business needs 17 pages of disclaimers to protect themselves. That's the unfortunate reality. In other territories (Germany/TUV comes to mind), there is more regulation and formal approval, but the downside is that you have far fewer choices on how you can modify your car. I've also seen some not-so-nice policies and practices related to the TUV approval, so that definitely isn't the ideal model. So, your choice boils down to research, trust, experience, and customer service. The customer has to figure out which company and product can provide the correct parts and support for their needs. You're technically and legally going to be on your own if you run into problems, regardless of which manufacturer you choose. In our case however, we will typically bend over backwards to help and support our customers, since we are all racers and enthusiasts and love what we do. We've all been on the other side of a problem, and we always try to do the right thing to keep our customers happy. |

I'm going to be honest, I wouldn't buy the 5040 kit if you told me anti-rattle clips were not going to be made. I don't dd my m3, but I don't want to hear that crap when driving on the weekend.
Also, my girlfriend likes to go to track events with me and she would go nuts hearing that particular noise. Thank you for revisiting this topic with Essex.

Honestly, the minor clicking/clack that the pads make from time to time don't bother me. You get used to it. It's worth the price for no-compromise performance on the track.

i'll have to take a ride in your car one of these days... i don't know what it sounds like, but i know elyse gets annoyed with squeaks/rattles and that would bug her, and in turn, she would bug me. "because race car" isn't a valid reason for her.

First off, I was one of the first customers on this forum to buy this kit 2 years ago and I have been 100% satisfied with its performance on the street and on the track. The lack of dust seals are a non-issue, never had any problems and I do a lot of driving in the twisties where there is quite a lot of tree debris/pine needles/dust/mud/water in some large elevation changes and varying temperature conditions. These are very durable brakes. The rear pad rattle is something that is present, but when I last replaced my Ferodo DS2500 pads (front and rear) the rattle was cut down significantly (I'd say down 50%) from previously. I think Ferodo made some slight design changes on the pad backing (despite same model number) that seemed to cut down the rear rattle. I can't speak for other pads.
Nonetheless the noise is only present with the windows down and over bumpy roads with imperfections that are noisy in the M3 to begin with and if you have a coilover kit, I think that noise is worse. Jeff, something to consider is to sell the clips as a separate optional item with the cost passed through to the customer...if they are say $100 a pair, it might be worth for it some customers who want complete quiet. The other possibility and I don't know if you guys looked into this, are titanium shims that are sold by others..inserting one may cut down on the rattle more and they (purportedly) offer greater cooling. These are relatively low cost as well. |

Like roastbeef, I don't DD my car, it's either date night/road trip or track.
I drive with the windows up and the piercing CLAK-CLAK (heard over an Akra Evo) over every road imperfection is a problem for me. Time to research the aforementioned shims, thanks for that tip, FogCity. Also, interesting to hear your feedback on the new set of DS2500's...

The vertical or longitudinal movement of the pad is what would typically cause a rattle. The ti shim just takes up slack between the pistons and pad backing plate, but it really shouldn't help with rattle. A ti shim is designed as a heat barrier. Road calipers with aluminum pistons use a ti shim as a crutch to prevent heat soak in the pistons and fluid. Since our calipers have ventilated stainless pistons, they are already great at rejecting heat. A ti shim doesn't offer much incremental value in our case. |

This is interesting, because I haven't noticed any rattle coming from the back of my 5040 kit, but I notice it from the 9660 fronts. I wonder if I'm just not realizing it's there? I tried to listen for it last night on my commute home, but even going over most bumps, I wouldn't even hear the fronts. I would have to hit it just right.

Ferodo DS2500s on the street. Ferodo DS1.11 at the track. It's a snug fit, so maybe there's less opportunity to rattle?

I am not hearing much rattle in the rear and I am runnjng the CP5040 back there. I did have a highly annoying noise upfront running two different types of pads (not at the same time) in the CP5060, which the anti rattle clips completely eliminated. That said, the clips are a bit tricky to install because i understand they are made for a caliper that has slightly different dimensions. Would love it if the clips were not necessary up front, but I have no issues with the rears. In terms of performance these brakes are phenomenal. I really cannot understand why any amateur driver would ever need the Pro 5000R kit when these are cheaper and lighter, and allow more wheel clearance.

We just finished up some great new videos on our Competition BBK's. We walk through each of the kit components and look at the shortcomings of road brakes when used on the track. Check them out below...they're worth a watch, and more to come!

I'm running the front and rear kit with Ferodo DS2500 pads. My installer said no anti-rattle clips were provided. They have used some grease / paste and I've not noticed any rattles or noises from the brakes at all from my initial runs of circa 60 miles.
During this time I've driven on several poorly maintained roads, with plently of broken surfaces, expansion joints, etc and no noise from the brakes that I'm aware of. I've performed the running-in actions too as per the instructions. |

I've run a few iterations of the 380 GT kit, it's not even a close comparison. AP crushes it. Benefits over the 380GT BBK:
This list goes on and on...Jeff and others can probably add to this. Watch the videos above, they do a great job of explaining all of the details.
