Generation 2 enhancements include:

- Fully internalized piston seals for added heat capability. This reduces the posibility of burned seals when used under "race" conditions.

- Revised caliper construction for firmer pedal feel.

- New silver powdercoat finish (previous finishes still available - red, black, or polished).

The new internal seal (stainless steel) pistons:

Are brake pads included? If not/so which pads are used on the BBK?

Would it also be smart to upgrade your brake lines w/a Big Brake set-up?

The UUC BBK includes everything you need (except replacement brake fluid). You get new pads (Hawk) and stainless steel lines.

Rob, I have to sway those look wonderful.

How long is the promotion going to be? I am getting my car back from the shop at the end of this week and do not know how much "lube" I am going to need to apply...

If it turns out to be not that much....

BTW, do you know if I can adapt stock E38 brakes to work on my E24? (or who to ask about this). I am currently running my E38's radial 16s on my E24, and the prospect of saving the 50s big brakes.... :redspot :buttrock

Also, anyway I can get BMW stamped on your BBK? (at extra cost..I will say I did it myself)

Danke.

The promotion officially expires one month from today.

I'm the guy to ask. :) They won't fit - E38 brakes are a one-chassis fitment.

Heh... only if I can pre-charge your credit card now for the legal fees when BMW's lawyers knock on my door. :rolleyes

Boo! Brembo and MOVit both offer any script, Ferrari script included, at additional charge..and Ferrari is one that is ventiment against anyone using anything. Do you know where I can get it done Post sale, prior to shipping...if you know what I mean... :embarrasm..maybe a PM discussion? :shifty

Wait, can I get silver with blue lettering saying Auraraptor? :eyecrazy

Sell 'em to the V8 crowd to offset some of your cost...

- Rob

FWIW, if you are in the market, this starts to become pretty attractive.

SS lines are ~$120 and pads (fronts only) can easily run $100+...Back this out of the sale price and this ain't a bad deal...

:( :( :( :(

I could machine the face down and have it re-engraved. Although it looks as if that's already been done for the UUC script to be placed. Might get too thin.

Also, does the reat kit also include 4 piston calipers?

That prob. is what I am going to end up doing

At a net of 3k, it is a good deal.

The logo is engraved, not painted/printed. We can do the calipers in a custom color for you, but it has to be a primary color... can't match your BMW paint. Blue, green, yellow, orange, purple, anything you want as long as you can wait 2-3 weeks.

The face isn't machined down further than normal; SSBC manufactures the calipers that way for us in the first place. However, I strongly urge you not to modify the calipers! Besides voiding the warranty, major machining may change the structural properties of the caliper.

- Rob

Yes.

It's fundamentally the same caliper but shallower to accomodate the thinner rear rotors, and machined to accept the smaller rear pistons for proper bias.

The cool thing is that the same pads are used front and rear, so replacing them is a lot simpler - just one pad part number to buy. Technically, you could rotate your pads (rear pads always wear less than fronts).

Rob the only 3 questions I have left:

1. Is ease of install significantly less then changing ones brake pads and rotors? Some BBK require a bit of work to simply 'fit'. I assume this also requires a modication to the dust sheild? Are instructions included so I can do this?

2. Not relating to the brakes, but rather your springs, is there an up and down on the rear springs? It looks nearly the same to me. I assumed the way with the lettering up is the proper way. Does it matter? (I was always thaught it does with progressive springs)

3. Can I get silver with Auraraptor in blue? (at additional cost) :D :cool :embarrasm

Installation is basically directly bolting them on. There is a slight trimming of the dust shield, nothing significant. With a good tin snips, you can certainly do it yourself.

Text upright, make sure both are the same way. In all reality, springs work the same no matter which direction they are installed - compression is compression.

Again, we cannot do any colored text, just the body of the caliper. I promise to look into the custom engraving for you. Got a specific font in mind? E-mail me privately on that - rob@shortshifter.com

I thought you said major machining may change the structural properties of the caliper? :D kidding of course.

Machining has been done on calipers with raised lettering, but I haven't seen it done on engraved calilpers. You could get blanks if UUC offered them specially, but it's more of a marketing thing not to do that.

I could have the lettering filled, then re-machined, and re-engraved. But you'd have to be crazy to be willing to spend that much :eek: As long as the wheel clearance is ample I'd get a thin plate in the shape of the caliper face with whatever you want stamped/egraved on it. Then Tig weld it on, or rivets. A lot of work it seems.

Wise-ass 750 owners. :)

Heh heh. I am a wise ass on occasion. But I have only the best intentions for UUC parts. I should, since I want a lot of them. Namely the exaust :buttrock . I just wanna see how far somebody will go to get some custom work done. I once quoted a guy $300 to mount some foglights in a somewhat custom location because I didn't want to do it, nor did I have the time for it. But to my surprise he said, "um, ok!" Makes me wonder what the other shops quoted him :eek: Custom work is great and I'm happy to do it when I have time. I just don't think many people are prepared to pay for it!

Heh heh. I am a wise ass on occasion. But I have only the best intentions for UUC parts. I should, since I want a lot of them. Namely the exaust :buttrock .

>sigh< The exhaust. If I got 30 seconds of free time for each piece of spam that I get in e-mail, I'd have about 200 years' worth of time to use up.

The exhaust is 99.9% done. Needs a tiny tweak (a slight tone at a specific rpm range that I don't like), but I need to finish the fabrication and tuning of the replacement performance cat section.

This week is turning out to have no time, and next week is SEMA. Argh.

I was visiting one of our dealers last week, let him drive the car. He said, "man, it sounds so nice... but when you get on it, it sounds so mean!"

No it's not. While this (and any BBK) install should be pretty straightforward, keep in mind that you are opening the brake system, thereby requiring that you bleed the brakes after everything is installed...

Other than that, you may need a fairly stout torque wrench and/or breaker bar to get the caliper bolts off - it depends...

Rob, do I lose the parking brake function with the rears?

As I said in an earlier post, after I find out the bill on my car, if I have anything left in the fund, I am prob. going to be getting a set, exact details to be worked out later.

Rob, do I lose the parking brake function with the rears?

You retain 100% e-brake functionality.

Funny thing is, the rear rotors are the only parts not manufactured in the USA... they're German. In fact, the rear rotors are Genuine BMW parts, the vented rotor from the 750iL (swirl-slotted and plated to match the fronts) - which explains why there is no problem with the parking brake!

Interesting, is it the stock rear rotor that you modify or the stock front that you put in the back?

Overall, what is the difference in weight of the setups?

It's the OE 750iL rear rotor, the vented design (740s have a solid rear). In all BMWs, the parking brake in a small drum brake within the center of the rear rotor, which is why that 750 rear rotor ends up being used in virtually all BBKs. With the larger aftermarket front rotor and the appropriate size pistons in the larger aftermarket calipers, that rotor fits into the brake torque calculations very nicely.

Overall, what is the difference in weight of the setups?

I don't have figures with me this evening (posting from home), but it is substantially less. The OE BMW calipers are cast iron and really quite heavy. Our calipers are aluminum... so even though they are larger, they weigh less. Likewise the front rotors, they have an aluminum center section bolted to the iron disk - while the rotor diameter and thickness is substantially more than the OE rotors, pulling all that weight out of the center makes it a wash, total weight is not increased.

Thank you Rob for all the help and answering all my questions!
