I have been looking for a big brake kit for my car and was not interested in the ford calipers from IE or expensive kits with brembo calipers or the set up by Massive Brakes out of the pacific north west, I think seattle.
Any way I figured I would put together a big brake set for me using the wilwood forged dynalite calipers and the VW corrado rotors from racingbrakes.com
When I first looked into this there was much unhappiness about the VW rotors and the risk of them comming apart. This is only on the factory rotors. The rotors made by racing brakes.com have the cooling vents on the inside of the rotor and not the outside like the VW rotors.
As for the calipers I didnt want the large superlite calipers because they are huge and would not fit in my 15x8 Rota slipsteams I just got. The dynalite caliper with 1 3/8" pistons are alittle on the big side for the factory master but I am using the 25mm 7 series master and a propotioning valve for the rear piped in befor the ABS pump.
So it comes down to a "Nice" setup that is larger than factory and smaller than other sets and cheaper than all others. The rotors are about 80.00 each and the calipers are available from summit racing for 124.95 each. The best parts is there are so many brake pad compounds available for these calipers.
I will be posting pictures of the setup soon and would be interested in selling adapters made from cold rolled steel. If you are interested let me know.
-
Just remember on a daily driver, the superlites don't have dust seals iirc so they will need to be monitored, especially if you drive through snow as well.
-
If this is a daily car with occasional or no track days...I'd suggest staying with stock rotors and calipers and use good brake pads. If you want big brakes...then go all the way and use Massivebrakes.com . What you are doing is useless IMHO.
-
isnt this exactly what 2002 maniac did?, use the same steel he did as he has had his for a while with out failure and done track days ect. I am interested in some brackets
Is all the stuff i hear about wilwoods being more of a racing caliper true? do they need more rebuilds them average calipers?
kind of sucks the rotors are so expensive but whatever
-

Please explain.
-
yeah its basiclly the same as the massive brakes kit except much cheaper

The Massive rotors and hats are much better, but otherwise this is a great setup.

yes, it's true. Parts are cheap though and they are very easy to rebuild.
-
The stock rotors and calipers offer plenty of braking power for the street and mild track usage. The point of big brake kits is you're using a much bigger disk that can dissipate a lot more heat and has more friction surface. Also the caliper is stronger. What I meant was that if you want the full benefits of upgraded brakes, go all out and use the big stuff...if not you're wasting your money. My opinion anyway.
-

well how often are we talking? like 20k miles? and whats the risk if they arent rebuild soon enough?
-
One of the ways that bigger rotors are better is swept area per wheel revolution. Another is the lever arm from caliper to wheel center. OEM brakes are adequate but you only need one stop that boils the fluid for it to be a history lesson.

What do you mean by "the big stuff"? These rotors are almost an inch bigger. One of the reasons this setup is so great, is that you can still use 15" wheels.
Last year as I progressively became a better track driver, I reached the limit of the stock brakes after a 30min session on street tires (azenis)! When you get on the track with race tires you can put alot of stress on the braking system. I have not had a hint of fade with this setup using good pads.
What is "mild track usage"? When I go to the track I dont putt around. I chase Evo's, STI's and Vettes :D.

annually is what they recommend.

I will post picture of the the set up. If it something you like fine I can make avalable the adapters If you dont want them thats fine too no skin off my nose. I liked the idea because they are inexspensive and effective. The track I go to has a 3800ft strait I have to stop at the end of that after hitting 120mph and do this with in 100ft and hope the little factory brakes can hold. The massive set up is fine for a 2800lbs M3 but not a 2400lb 318is in my opinion. I was hesitant to mention this set up because of the work I put into it and it seams like there is no love for the idea so go buy your massive brakes and I will by my corrado rotors and dynalite calipers and have fun my way. thank you
-
I'd be interested.. I'd like some bigger brakes behind my ACS wheels the ate's aren't cutting it :P

lol your easily offended. I was just stating my opinion with what I know. If you don't want opinions don't post. Sorry if I offended you. I know the stock brakes limits, I experienced them. I guess I hadn't really looked at the price of your setup...if the result is what 2002maniac says it is, then I guess for the price it's nice.

This is an update on the brake set up I am using. Here are pictures of the stuff mounted and the calipers with the adapter. If any one is still interested I would sell the adapters made of 7075 aluminum with the holes taped and you have to supply the caliper ( part # 120-6806 124.95 from summit racing) and the rotors from racingbrake.com for a G60 corrado which is 180mmx22mm and there is some modification to the center of the rotors which need to be opened up by 1 mm to fit over the BMW hub and there is an edge of the BMW hub that needs to be chamfered to allow the wheel to bottom on the new rotors and the hub surface otherwise the rotor is loose on the hub and the wheel wont tighten onto the hub. The brake lines are avalaible from IE for 20.00 each. If you dont like this idea its you life but If you do I will be selling the adapters fro 100.00 shipped.
-
i have a feeling that if you make them out of steel a lot more people will want them
-
I can make them from steel but the machining cost is higher and the strenght is just as high with the aluminum, and lighter.
-
I just wouldnt trust aluminum especially over the long term.
so do you have the setup working? how is it?

Have you mentioned, caliper is made from aluminum ;)
-
the forces acting are a lot different, plus its tried and tested thousands of times over
-
dino, stock E30 caliper bolt strenght is 10.9, dont use 8.8.
-
I am using 10.9 bolts, thank you.
-
For those who want to know I installed the new Wilwood calipers with the adapters and the Vw Corrado rotors and the IE brake lines and finaly the 25mm master cyl. I cant put into words how amazing the brakes are. WOW holy crap. I have street pads in the and am totaly dumbfounded by the increadable brake feel and stopping power.
-
i would be interested in some brackets in steel. or maybe aluminum after youve tested them more. Is there enough room for nuts to be used so the bolts dont just thread into the aluminum?
-
nope you have to thread into the adapter plate.
-
Is it posible to fit adapter from other caliper side?
-
I guess you could but the offset sould be different. I had no problem with threading into the steel adapter since it is half an inch thick and more than the thickness of the fasteners. From what I have always heard as the norm for fasteneners is you want the material you are threading into to be the thickness of the fasteners. So I am using 10mm bolts to fasten the caliper to the adapter and 12mm bolts to fasten the adapter to the hub and the material is .5 inches thick or 12.7mm so I am with in this norm.
-
steel adapter
so did you make them from steel or is that a typo
-
The first one is made of cold rolled steel and cost me an arm and a leg to get prototyped. If I do sell them I would make them from 7075 aluminum. If there is a high enough demand for steel I could talk to the machinest and see what it would cost to make them from steel.
-
well ill take a steel one depending on how much it is. It seems kind of weird to use steel for yourself and sell aluminum ones but whatever. if you want an aluminum ill take your steel
-
so is anything going to happen with this or what?
-
As far as I know, he'll make aluminum brackets for anyone that is interested. He wants to avoid the higher cost of mateials and machine work.
-
dino245, is there nead for brake balance adjuster?
I just bought one in ebay.. ;) 40$

hmmm. does steel really cost more then aluminum these days? I do understand that machining it is harder though. How much did you pay for your steel dino
-
what about just giving the drawings?

The cold rolled steel does cost a lot, not sure as compared to aluminum, but I'd think near eachother. The main difference is how hard coldrolled is. That stuff is a pain in the butt to drill through and tap.
-
I never had a problem with the stock setup beside the looks. The car tips the scale at 2.500lbs, Just upgrade the pads?

Yea but he does road race events i believe. He said it in one of his posts, "The track I go to has a 3800ft strait I have to stop at the end of that after hitting 120mph and do this with in 100ft and hope the little factory brakes can hold.The track I go to has a 3800ft strait I have to stop at the end of that after hitting 120mph and do this with in 100ft and hope the little factory brakes can hold."

I installed one with my setup and i dont think it's needed. I have mine open all the way and the bias is really nice with the M3 MC
