Brake Backing Plates?

[matt]

I am very pleased with mine still. I've run 2 days at road atlanta on them and never managed to fade my brakes at all.

back from the dead, did you ever buy any? There is a thread that mention these, and they're half the price:

Sam: I've started a thread about this over on Bimmerforums. The vendor who claimed that non-lipped backing plates cause rotor/pad problems has responded there.

ben,
would you please post pics when you get yours in??

i wonder if the stock backing plate could be made to fit a hose for cooling?

I think if you have the metal working tools and skills to do that, you might as well just make your own backing plates with cooling hose connection.

I'll definitely be snapping photos of whichever ones I get.

Maybe a cheap solution is to add a piece of rubber hose sliced to fit around the edge of these cheaper brake backing plates?

I'm 99% positive that under hard enough driving (and therefore braking) conditions to make these vented backing plates worthwhile, rubber hose would simply melt.

you're pretty brokeback, ben

Uh, you've heard from who? Anyone who's actually used them?

A guy from Vtmotorsports (who makes a product 3 times more expensive, but has these lips) said this. He said he has done extensive on track testing and without the lip air goes across the rotor face as opposed to cooling the disc via the vanes. He says that it leads to premature cracking of rotors and improper pad wear.
I do not know the guy personally and have not experienced this myself, that is why I was asking. I'm all for these brake ducts if they work as well as the lipped $$ versions. I hate the idea of paying 300 bucks for a pretty basic piece of metal.
I take it you have not had any problems on track with these ducts?

I've heard that the lack of lip increases air flow across the rotor face and can lead to problems.

Anyone have problems with cracked rotors with these backing plates? I've heard that the lack of lip increases air flow across the rotor face and can lead to problems.

You will still have to either cut up and destroy the backing plates (the fun way) or remove the hub (the hard way) to get the old backing plates off. No way around that. But it is nice to be able to attach the new plates without taking the hubs off.

No biggie...I don't mind destroying the stock pieces.

M3 ones will not work on a non-M suspension.

Also, using a style with a U cutout makes like much easier than pulling hubs.

Thanks for the info.

I have a set also. I am very happy with the fit and finish although I haven't connected the hose yet. They are very simple, light and fit great. Chuck (owner of Factory 3 Performance) is a great guy and doing business with him is a pleasure. :up:

BTW: For 88+ guys, he also has an awesome little piece that connects to the back of the factory brake duct to adapt it to 3" hose to the backing plates, so you don't need to hack up your valence for a duct, or duct tape the hose to factory one. I have a set of these also, and they're awesome.

Thanks for the input!

I saw that adapter piece, I'll be getting a pair of those too :).
