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

[AusFahrt]

Long time lurker, first post as I can't believe what I am reading.

Looks like a royal crapstorm of fear coming from MassiveLie. So not professional and childish. Rob I am definitely buying your kit! Got your awesome swaybars already and they're the best.

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.

Again, I was comparing it to Lee's kit that he made a point about... and the comparison diagram is clearly marked.

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!)

Oh, one thing not shown in those diagrams... pad backing plate relief.

Pad shape 7816 (as used in Dynapro) has "ears" that stick up at the corners, above the caliper. This raises the effective radial clearance requirement. That is not shown in the diagrams.

Pad shape HB237 (as used by UUC) does not have these ears at all, the pad itself barely sticks above the caliper and just in the center... and this is already represented on the UUC diagrams for clearance.

Don't worry Kshing. I am just having fun with a mouse. Pretty sure our buddys at Bimmerworld would enjoy all this rethoric.

BTW Rob. Do you remember that kit with flat hats? Yup. That's what I was refering too when I talked about offset.


BTW. How many two-piece hats and full kits have you designed in your lifetime? I am not talking simple brackets to fit a caliper to an OEM rotor, then sold at a very high price. So, I really enjoy the expert's talking. Why is that you offer only one kit to the e30 chassis? Third version of the same kit? Right? What was wrong with the other versions and how many times do you have to try to make it right?

And for your information, the only occurance with the rotor contacting the steering rubber boot is when cheap aftermarket ball joints are used. Get proper quality parts of the proper size, and there's no problem. ;-)

cheap shot! no one is discussing the old UUC kits, just the same way no one is buying your old kits. improvement is normal and expected, and yes we can form opinions based on previous mistakes or shortcomings, but to bring that out, is low.

why dont we keep the discussion technical as before?

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

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?

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..

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

[Massive Lee]

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

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.

[Rob@UUC]

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

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.

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

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

[Rob@UUC]

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!

[Rob@UUC]

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

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