Not sure all I know it's I ordered 2006 z4 calipers and they didn't work maybe they gave me 3.0 not sure but I held then up side by side and there is a clear difference

This may be a dumb question, but will using these adapters have any impact on ABS performance? I'm likely going to go with the E36 M3 version (it's a track car that I've already removed the parking brake from).

Yes/no. The abs sensor is retained so if a wheel locks up, abs will kick in. If you continually lock up front vs rear or rear vs front, you may need a bias/proportioning valve to put more pressure front/rear or play with the brake pad compounds.

I don't suppose you have a part number for the caliper that worked?

Sounds cool

if i swap out my rotors, calipers, and carrier with this kit, will I still be able to use my oem pads? I just replaced my pads....they are so new :D

sirius815 06-10-2018 03:59 AM

Cross-reference the part numbers. I don't recall exactly.

Has anyone done the M3 Extreme kit? I tried putting mine on today and found two issues. First, my brake lines won't reach with the M3 calipers. Anyone know if the E36 M3 rear line is longer, or have a solution?

Second, once everything gets bolted up my pad hangs off the outside edge of the rotor by about 1/8". It's probably not going to make a notable difference, but I'd hate to give up surface area if I don't have to. Did anyone else experience that, and if so how did you correct it?

I don't have any experience with this kit in particular. However a solution would just be to extend the hardline to get a soft line from local store/look up on REALOEM and see length.

Can't say about the pad fitment, but it shouldn't hurt much.

I took BimmerBum's advice when buying and stayed stock with more aggressive pad choice. However it's a street car that I putz around in.

I know for the cost Bluebimma's CL600 rear brake kit he used worked quite well and was extremely cheap. As long as you can fab some hangers.

AAAAHHHHHH!!!!
 
I can't believe my luck with this crap!! :mad::mad::mad:

I bought this adapter from SRS back in October of 2017. I had the exact problems that all of you have said you had. I talked with Simon and he sent me the other (E30) adapter. I half ass fitted it and it seemed like it was going to work. Unfortunately I haven't readdressed the situation until today ... all afternoon I've been fitting and grinding and cutting to try to get this all to fit. :mad::mad::mad: Now to find out that NONE of the parts I bought over a year ago will work!!! :mad::mad::mad:

Even worse is that I was trying to use E36 M3 calipers with this kit so I bought two sets! M3 pads and 128i rotors!!! AAAHHHH ... a VERY EXPENSIVE track set and a daily driver set!!! AAAAAHHAHAHAHAAHAA ... Goddamn I can't believe my luck!! :mad::mad: I also spent several hours the other day rebuilding the M3 calipers!! What a COLOSSAL FREAKING WASTE OF MY TIME AND MONEY!!!!!!!:mad::mad::mad::mad::mad::mad::mad:

Well, in Simon's defense, he did update the product page quite some time ago to reflect the correct parts.

I used his kit with all M3 stuff. I bought re-manufactured calipers (even powdercoated red!) and new rotors from Rock Auto super cheap; I saw no need for sourcing and pull-it yard stuff.

The only two issues I’ve had are losing the parking brake (track car...more weight gone!) and the short flex line issue. My solution on that was to run the calipers on the opposite sides of the car so the (stock size, but SS braided) lines reach the caliper fittings. This works fine, EXCEPT you have to pull the caliper to bleed the rear (the fittings are aimed down and are lower than the high spot). Eventually, I’ll source some 90-degree brake fittings and swap the calipers back; that will simplify the bleeding.

I’m also going to add a proportioning valve since I have no ABS and there’s a little too much rear bias with my gutted setup (very light rear).

Ya ... it’s my bad for waiting so long to follow up with this project. I just wish he would’ve gotten the parts/information correct the first time when he sold this kit originally. [emoji853]

I have somehow managed to ridiculously luck out and there was a 3.0 Z4 at my local pickapart. I went and scored everything I needed today for a little over $100. [emoji16][emoji16]
