I read in a BMW Mag hat 740i Calipers fit straight onto the E36 barke system, this sounds like it would be a great way to upgrade the standard E36 calipers with some Brembo ones from the 740i. Also read that you should change the disks if you do this, what disks should be used?

Has anyone done this? Did you have any problems? & most important of all did it work?

I now have my doner E36 M3 Evo donner car, track days here I come.....

No, but it's not 7 series, it 8 series calipers and ideally, you should mate them to E46 325mm disks. Apparently, you need 15mm spacers to fit under std wheels, but I'm sure there are others around here who know more than I.

Personally I wouldn't bother, the main problem with the E36 brakes are ok oin track if you run decent pads, fluid and hoses

nono

I run uprated pads, fluid and hoses. The brakes are still shite smile

No matter which way you look at it, the E36 weighs ~1500kg's (this of course assumes we are talking about cars of standard weight), punts out ~300bhp and is stopped by single piston sliding callipers. Even BMW have now admitted defeat by fitting the E92 with some decent stoppers. Everyone I've spoken to who tracks their E36 and E46 (even the CSL!) has said that the brakes are ths single biggest let down and have subsequently uprated them.

To the OP, if you check out e36coupe.com (you'll need to wait an age to register if you're not signed up) you'll see an evergreen thread relating to this popular upgrade to 8-series dics.

Although it does seem that quite a few people are happy with Evo calipers, Evo disks and Pagids, so I guess it all depends how heavy you are on brakes. Evo disks are a well known upgrade for E36 M3 owners, so they can't be all that bad.

sorry that's not entirely true the E46's brakes admittedly are not up to par on a car of that sort, it is alot heavier than the E36 but but they are certainly not crap, it is well known that standard brakes on an E36 are ok if you use the right pad and fluid combination, I raced an E36 standard brakes to start with, then went to 4 pots, then 6 pots, and I now track a Z4M with standard brakes and they're perfectly ok for trackdays. If you want to spend 4x more than upgrading what's already there then yes they'll be better but by only about 5-10%more and most trackday goers won't get anywhere near the limits that OEM brakes are capable of

But shirley your racing E36 is a good deal lighter than the stock car? As above, I've uprated the hoses,(DS3000) and fluid and the brakes are still poo. Not only is there not enough bite, but I still get significant fade after 4-5 laps of my local circuit.

yes it is but it wasn't always, I also tracked my standard E46 and now Z4M, you don't need AP's to make a good job of the a trackday with OEM brakes, try changing your fluid, I only use SRF or AP PRF660 and use track specific pads like Mintex F4r, then swap OEM back in there for the ride home, works perfectly fine and I'm hard on brakes

What have you uprated pads to, though, as I hear the Pagid's make a big difference. I also know a pal who has fitted the combination I mentioned to a mates E36 M3 (non-Evo) and certainly on the road, he thought the stopping power was extremely impressive.

Pagid RS-29's, fluid, hoses 55 laps of the Ring, 2 track days at Cadwell Park and 2 at Croft on the same pads, no brake fade in an M3 GT running very sticky tyres.

As Taffyracer says, these are ample for track use. Compared to the 6 pot AP's I had on my CSL, they didnt stop me £2k better! I can only see that the stopping power was about 5% better.

That's my point, they're only 5% better, most people will never get close to within 5% of the total braking ability, especially on a trackday, I love AP's, think they're superb and I have a set for my car when my OEM discs are shagged, but the OEM brakes can be made nearly as good for 95% of trackday goers

I've always found M car brakes to be rubbish, especially if you fit Eurocarpart cheap pads hehe
