UUC - Big Brake Kit - Direct Fit caliper, 11.75" rotor

[McGyver]

well now i wish i had $850 to spend. i would be all over a set from you.

[Rob@UUC]

would these fit bbs rs001's?

Probably no issue with a 16x8 et20? The hub is pretty deep on the wheel to get that offset.

Looks like a quality product. I would love to knock 4lbs of unsprung mass off each wheel, get better breaking and still be able to use 15" wheels. When it comes time to get brakes for my e30, I will be looking your way.

A rear kit would be nice to see as well.

Probably... but half of the clearance issue is the space between hub plane and spoke plane, and/or how the spokes curve.

Use the fitment diagram anyway just to make sure.

Just curious if you have a fitment template that backs up the claim that this caliper gives more wheel clearance than others on the market.

The fitment template has just been added to our website, see the .pdf download link in the FAQ section of this page:

I've already done a bit of the hard work for you...

As expected, there is a lot more clearance compared to a Superlite with the 1.25" rotor (same 11.75" / 298mm diameter). Also, the Superlite kit's rotor is moved inboard a few millimeters (probably <5mm), but looks like it would require the heat shields to be removed.



Interestingly enough, compared to a Dynapro with a smaller 280mm modified Volkswagen Corrado rotor, clearance is still a little better outboard toward the spokes with the UUC caliper, and total radial (caliper radial profile changes as view goes around) is very similar:



Hope this helps!

awesome, i will confirm fitment with the popular TRM 15x8 wheel tonight.

also, maybe give credit to massive for the fitment diagrams you took from his website ;)

Definitely - let me make it clear that those diagrams are not a guess at all, but fact!

Maybe I can come by and we change a front wheel on the car equipped with the brakes?

You don't even have to ask... just show up!

(But call ahead of time to make sure I drove the E30 that day.)

I'll even take a cool photo with the zoom lens. Use it on the site or something. Have big open holes between the spokes. It'll be soon.

I don't think that Rob would intentionally misinform potential customers, but strange things happen when Rob mentions "facts". Like Rob using the wrong template, the one of the thicker 1.25" kit to try to make a point. So, let's compare bananas and bananas and use the appropriate template, the one for the 11.75" x 0.81" kit, same size rotor as Rob is using. Then results would be different. Yes Rob. I offer different kits. Not one-size-fits-all. And different pistons sizes too...



The amount of extra width of the Superlite caliper would be only 8,5mm, not 20mm as the "tweaked" demonstration seems to imply. ;-)

i can confirm lee's diagram, this is the exact result i got when i compared lee's sport kit with UUC's new kit, not what Rob posted above. the profile is different, and until i put both of them to my wheels, im not sure which provides better clearance.

one thing is clear, the UUC kit does not provide tons more radial clearance that was initially suggested. but it does provide that small little 1x0.5cm of extra clearance at a critical spot. might just be enough (can't forget about wheel balancing weights!)

lee, where exactly did you suggest trimming the superlite caliper to provide clearance for the TRM 15x8 wheel?

[Rob@UUC]

Strange things happen when Rob mentions "facts". Like Rob using the wrong template, the one of the thicker 1.25" kit to try to make a point. So, why not use the appropriate template, the one for the 11.75" x 0.81" kit, same size rotor as Rob is using? Then results would be totally different.

Funny thing happens when Lee forgets what he's written previously:

That new kit's hat is flat and brings the outer face of the rotor even further out than Massive's thicker Race kit with a whopping 11.75" x 1.25" disc. Meaning that Massive's Sport kit (below UUC's) which uses a disc of the same 11.75" x 0.81" dimension is at least (32mm - 21mm) 11mm more inward (I think it is more like 13mm).

Addressing that, the proof is in the comparison diagram. The UUC hat is not flat (#1 mistake), UUC's rotor face is further inboard (#2 mistake), and it's physically impossible for your rotor to be inboard 13mm more (#3 mistake) when there is only 8mm between UUC's rotor and the tie rod.

All facts. Indisputable facts.

To put it bluntly, Lee, you are making things up and are outright wrong.

You've been wrong about a lot of assumptions about our kit, a lot of your general facts, and it's all been in an atmosphere of unsolicited attack.

... and your potential customers are seeing this behavior. Please continue!

Yes Rob. I offer different kits. Not one-size-fits-all. And different pistons sizes too...

Since you bring it up, what's wrong with Lee's kits?

1) Excessive front bias. Cars nosedive, not using rear brakes.

2) Excessively heavy front rotors. "Massive" rotors do not have cooling benefits that are worth the weight, which negatively affects vehicle dynamics in acceleration and steering response.

3) Massive spacers required.

The amount of extra width of the Superlite caliper would be only 8,5mm, not 20mm as the "tweaked" demonstration seems to imply.

It's 20mm as the example you brought up with your "magic" 13mm ("you think") rotor offset that puts it within the steering knuckle ball joint.

More made up numbers, I suppose? Or maybe facts that I verified.

BTW Is that really a 20mm thick hat on the picture?

Are your fitment diagrams really only showing a profile and not a full radial sweep?

geez what a catfight.. am i glad spec e30 requires stock calipers :)
