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

[Rob@UUC]

UUC should look into making a caliper bracket and rotor setup to allow for rear e36m3 brake calipers to be used on the ti 5lug swap :-D

Here's a better idea; why don't I just do an E30 rear BBK and offer a 5-lug rotor option, and you can just use the E30 M3 wheel bearing in the standard E30 trailing arm.

That'd save you a lot of time and money.

If you're using E36 or E46 front hubs, use one of my standard kits for those cars to match.

Well, a fair amount of us already have the 5lug swap in, and there would be offset issues with using e36 front end and e30m3 rear end stuff. Massive has a $1500 rear bbk for the 318ti, but there's not much sense in me using race calipers in the rear (and dropping a ton of money) and using e36m3 calipers up front, and it seems that just doing an adapter would be a lot cheaper.

I'm not sure how hard it would be to do, I certainly don't have the skills to manufacture it, just throwing out an idea :-). e36m3 rear calipers aren't very expensive, and would match the front calipers for those of us with the 5lug swap. If it could be done for a reasonable price it would be awesome and I'm sure there would be a market for it, if not thats okay too. Like I said, just throwing out an idea for you guys.

UUC: My car is S52 powered, meaning it has an E32 booster and master cylinder. Will this effect the performance of your kit?

I was looking into a brake upgrade a while ago and was considering a Willwood kit, but Micky at Bullet said the brackets flex. I am really happy that there is now an alternative...

Great product
Good price
USA made / distributed
Common courtesy, decency, professionalism

Excellent combo.

Since I am directly concerned in this comment, please allow me to straighten some facts. Massive is not a person. It's a company. And since this is only your fourth post here, please allow me to ask you in what type of automotive business you are. What's the company's name? Also, if you are seriously into automotive stuff, I guess you should at least take a look at the different options before making your own judgement on what equipment is best. This is what professionals in the automotive business do.

In regard of your comment about "Made in the USA", please let me pinpoint that "Wilwood" calipers and rotors are made in the USA as far as I remember. Not sourced from China as many automotive products, which I am sure you wouldn't sell. Right?

That being said, please feel free to bring any technical argument if you want to judge what product is best or doesn't deserve to be looked at. Otherwise, I'd believe your choice is not well founded. For your enlightment, here's a shot of what you are missing. Feel free to contact me for any request of info.

I can't believe you posted that :giggle:

Poster seemed to be of the shy type despite claiming he is a professional in the automotive business.

Also, some misinformation in this thread. Such as brackets in the Wilwood kit flexing. Wilwood doesn't make any e30 kit. Therefore the buddy at Bullet needs to precise his thoughts too.

Um, I've seen Willwood calipers (with brackets on E30's), and I'm pretty sure they weren't one off's. The guys at Bullet know there stuff, so I'll defer to their expertise.

As far as the hub parts front vs. rear, it doesn't matter; all that matters is what brake components you are using. I presented the idea based on aftermarket calipers simply as a possibility that could be done in a way that would actually pull a big chunk of cost out of the equation... the E30 M3 parts are getting pricey, so if I could configure a kit that could be properly built to work with mixed parts, then so much the better. But I do understand your point.

I don't have the 318ti caliper lug dimensions at hand at the moment, but I suspect there is going to be an issue with holes too close together, or I'd have to offset the caliper somewhat, maybe about 10°-15°.

e36m3 rear calipers aren't very expensive, and would match the front calipers for those of us with the 5lug swap. If it could be done for a reasonable price it would be awesome and I'm sure there would be a market for it, if not thats okay too. Like I said, just throwing out an idea for you guys.

Definitely something to consider. I will explore as time permits.

Not at all. All that the E32 parts are doing is providing more hydraulic assisted, distributed through the system the same proportions as the original booster/master.

As you're getting more assist with your current brakes, you will have the same effect with our brakes.

Bottom line: it will all work perfectly fine.

I was looking into a brake upgrade a while ago and was considering a Willwood kit, but Micky at Bullet said the brackets flex. I am really happy that there is now an alternative...

Depends whose brackets, of course. I've seen some real horror show brackets, usually aluminum, that flex and even break. A friend of mine had another brand aftermarket kit using Wilwood calipers. He went through 3 sets of those brackets going bad. I would have shipped all that stuff back after the first set! Clearly the manufacturer had no idea what they were doing.

In any of our Wilwood-based kits, we use a milspec heat-treated steel. If your car were put in a crusher, our brackets might be the only parts to survive! :)

Our own UUC caliper kits, of course, have integrated mounting points that are over-built as discussed in an earlier post in this thread.

Thanks very much, appreciate the kind words!

Just to make sure I'm being clear, the kit would use the e36m3 rear calipers, not e30m3 rear calipers, as most of us are running e36m3 front brakes. You might have been talking about not using the e30m3 rear hubs, but I just want to make sure you don't think I mean using e30m3 rear calipers :-).

If you could come up with something that would be awesome, I bet a lot of the 5lug guys would love it!

I might be looking into this kit. I didnt really find them on the with disk and pads for a 5 lug swap.

Any options for me or discounts! :D

No, I'm following what you're saying. I'm saying E30 standard and E30 M3 rear trailing arms are the same part, so you can install just the E30 M3 bearing/hub into the trailing arms you already have instead of getting 318ti trailing arms.

Then, either a bracket to use E36 M3 calipers, or I make a regular E30 rear BBK and offer 5-lug rotors and pair it with a matching front BBK as we would normally use with the E36 (piston sizes adjusted to match the rear) for your transplanted E36 front hubs.

Either one is viable, the second option is more technically interesting. :)

[balooshinakus]

Gotcha. I'm 99.9% sure that the 318ti and e30 have the same mounting points for the brake caliper, because people install inline6 z3 hubs into the e30 trailing arm (the bearing for the i6 z3 and e30 are the same), and then use the 318ti brakes mounted to the e30 trailing arm (this is what I am doing). I suppose the difference would lie in the rotors used, but I am not really sure how that works out from your standpoint.

[Rob@UUC]

For a 5-lug swap car, if you've used E36 or E46 hubs, you can select from our existing Wilwood or even Alcon-based kits on our website.

You won't see an E30 M3 kit on our website, but we do an Alcon kit sold exclusively through Elephant Motorsports.

^I couldnt really see prices for disk and bigger brakes. Just looking for the 2 front. And i used e36 parts.

Not sure exactly what you're asking for... but all prices for all parts are on our website. Our website is designed to be completely self-sufficient with all product info, tech data, and pricing.
