Ultimate brake thread

[EricB]

Thanks for the the advice tzei.  Rodolfo, you may have just broadened my view of the world.  Do you know if the Performance Friction caliper and/or discs will bolt onto the Massive Brakes caliper mount or center hat, respectively?  I will give them a call tomorrow, but it seems like that might be the way to go.....with the addition of some new ducting.

The PFC disc bolts directly to the Massive brake hat . 8 x 7 bolt pattern. You can use a 32mm or a 20mm thickness disc. I will use the 32mm. The part number is 299.32.0040.01 (left 40mm friction material pad height) 299.32.0040.02 (right) or 299.32.0045.01-02 (45 mm pad height).
I will use a PFC caliper 94.323.410.440.xx the last 2nbers depend on the caliper position. Left/right leading/trailing it has 2 41mm pistons and 2 44mm pistons. There are also other sizes. These work great with rear 29mm and 36.5mm pistons, also zr94 or zr34 calipers.

There is also a bracket for this caliper, i dont have the number here, and you can easily modify the ones you have or make new ones for the new bracket.

Can anyone advise as to the part number/source for the caliper bracket discussed above?  I've got a set of Massive brake hats but nothing else.  Thanks, Doug

Outer lip is cut all round like on the turbo dust shields and made some ducts to bring air right into the center.

Bu it's a street car that has to go through TÜV approval for a race car only ducts and no dust shields.

Hubs made of 7075 and Brake pistons from wolfram (tungsten) carbide coated titanium.

I have to make this simple because I am not very smart.

Front, old school 320i vented rotors with 528i 4 piston calipers and hawk pads 3" vent lines from my air dam.

Rear, VW rotors and calipers hawk pads. I can lay down 4 black stripes with r compound 225/45/15's with almost no fade.

That indicates to me that the brakes are adequate. The air removing brake heat is very important.

I have been radared well over 140 at the Auto Club Speedway Roval.

Sexy brakes are cool but solve problems don't create them.

work great on tii struts.

 

As to the brackets that the bumper asked about, that MIGHT have turned into a DIY proposition.

Lee still makes his, for the Wilwood parts.

This question grew out of a discussion with mlytle regarding brakes.  I have owned 320i vented front brakes and 15" wheel big brake kits from Ireland Engineering and Massive Brakes.  mlytle had pointed out the bigger brakes are limited in hard use by the larger rotors(300mm) having too much leverage on the tii wheel bearings.  I have now thoroughly (and expensively) tested this theory and think it is correct.  Has anyone ever made a strut that could fit the geometry of a 2002 and has an E30 wheel bearing?  Are E30 wheel bearings even that much bigger?  It seems like this would be a fantastic way to get brake options that would be the same size, but work better.  I had a brief exchange with Ken from 2002underground.com and it sounds like he is thinking of making such a product.  Does anyone else think this would be a great idea or is there some obvious reason this is a bad idea?  I was also wondering if anyone has pictures of brake ducting that has been installed without a front spoiler on a 2002?  Thanks

 

To find some answers for your specific case you might want to look in the direction of repeated and excessive forward weight transfer as you would expect under repeated heavy braking with big modern tires , especially when coupled with improper spec, low-grade or non-existent lube. It's what happens when you try to make something do what the design engineers never intended it to do...or you could buy a Porsche.  The real answer of course requires the use of Laplace transforms...it's a legendre polynomial function ?.

Here's a Greek m2 that uses a massive 7 series spindle/bearing.

 

 

and a left of field double caliper set-up.

 

 

Just fyi.
