A little bit of surgery... I promise, it did not hurt that much...

Tadaaa...

If you are nice to me I will post the fronts on Wednesday when I install them... Either way the kit fits like a glove. Cheaper than any other alternative and offers an unlimited choice of performance pads and OEM discs.. :thumbsup:
 
VERY intrested .... more more more!!! what p car these from?? boxster? did you make your own caliper spacer??? even better we can use the stock disc...... awesome!!
 
i have to day this is such an great idea please post up in detail about the kit and what bits are needed ect ect im soo going to follow you on this!!!
 
He, he, I knew it would generate a bit of interest... I am using 996 calipers front and rear with custom adapter brackets made on a CNC machine. Everything else stays standard - BMW OEM discs front and rear, BMW OEM brake lines front and rear. The only mod required is to cut away a tiny section of the rear dust shield and space the front wheels 15mm out with a hub-centric spacer. We have tried this kit on the G-Power Evo III Z3M Coupe which runs low 12s on street rubber. We also have the front kit on a CSL, which has done around 80 laps of the Ring with it in the very low 8s (rest of the car is bone stock including the suspension) and also done a round trip to Stelvio and back without issues.

Are they as good as AP 6-pots? The honest answer is almost... Does the kit cost anywhere near the AP's cost? No way... Does it cost anywhere near the AP's running costs? No, it doesn't - after all I am using OEM discs and pads fitted to a production Porsche from 1998 to 2008.

Can supply a complete kit or brackets... People are more than welcome to try it in my car once I have it all installed. I will be at Silverstone this Sunday (21st Nov)

how much for a complete kit???? will i need the spacer, im running gen CSL alloys? i think im going to come and see this kit @ silverstone!!! this could quite possibly save me a fortune ;-) so im guessing a square 4 pots front n rear?? I love the fact i keep my rotors n all my own hardware.... This is just what us ///m owners need!!! Great.

And the Porsche pads too :) You will need to space the front wheels by 12mm if you are running original CSLs. That's what we had to do on the E46 CSL, which first got the kit. Unfortunately, there is no escaping the crappy offset on the front wheels of our cars. Even if you fit AP Racing brakes or KW suspension, you would still have to space the front wheels out by a minimum of 12mm. Andy (sixspeed) and Rich both had to do it with theirs... As said before - this is almost as good as the AP kit, but ultimately, not a like for like match. Think of it as E46 M3 = standard brakes, Z4MC = Porsche Brembo kit, E46 M3 CSL = AP Racing 6-pots. You can buy a Z4MC 30% cheaper than a CSL, but the performance of ours is not 30% less, is it :)

One more time - the kit uses OEM discs and OEM length hoses and Porsche calipers/pads...

I am planning to keep the Porsche logos on the calipers, just so I can pee off the stealer when the car goes in next for warranty work :poke:
 
I've always wondered whether Porsche brakes would fit... Question is would it work for a non-M Z4... Specifically a 2004 3.0i SE? :?
 
Can you give us your driving impressions? Or point to someplace that a user has reviewed such a kit? These will not fit with the stock 18inch wheels right..?
 
Oh and another thing that just occurred to me, what about the brake pad sensors? Do the Porsche application brake pads come with those indentations for the re-installation of the pad sensors or what?
 
Driving Impressions - the standard brakes are not bad for one or two stops from huge speeds, however they don't stand up well to repeated track use (abuse). The Porsche caliper may stop you only a fraction quicker, but where they really excel is the ability to modulate your braking and their resistance to fade. The Porsche brake pad from memory is about 35% bigger than the BMW one. To give you an idea - if the kit is good enough for an E46 M3 which competes in the ADAC 24hrs of the Nurburgring, then it is good enough for me.

Brake pad sensor - the Porsche pad has the same recess as the BMW pad. In fact Porsche fit wear sensors on all four corners on each pad! Thus if you want to have the sensor plugged in, it is not a problem. I prefer to check mine visually since I don't want to end up somewehere in the middle of nowehere with the light on.

The kit fits well with standard 18" Z4MC and Z4MR wheels. That's what I am using since I actually like the design and wanted to be different from the CSL fan boys :P My wheels are gloss black to go with the Imola Red...

I told my insurance company and they were happy about it - after all I am increasing the safety margin on the car and not power output, which they usually hate. Premium has stayed the same.

Cheburator, any ideas about it fitting on a non-M? :?

I honestly don't know - in theory it should not be a problem, but you need to look into the following:

- is the 3.0Si using the same calipers as the E46 M3 CSL/Z4MC
- is the 3.0Si using the same king pin as the E46 M3
- what is the offset of the 3.0Si brake disc vs. the CSL/Z4MC disc

If the answers to the above are the same, then it will work... Beware of different part numbers which often describe one and the same thing. For example, the front ATE brake caliper is used on the following vehicles - Porsche 928S, Porsche 928S2, BMW E28 535i, BMW E24 635CSI, BMW E30 M3, BMW E36 M3, BMW E46 M3 and the Z4MC. Sure, pad size is different by a small variation, but ultimately I can go to a 1980 Porsche 928 S and swap calipers. Real OEM will not tell you that though... Maybe you need to compare the real parts or ask someone who is actually in the trade?

My line of work is completely different from cars, they are just a hobby and a wallet emptying device :lol:
 
So basically the only thing you would need for this upgrade (other than the callipers themselves and new pads) is the custom brackets. Where do you get those? Quality? Durability?

This is a very interesting mod and one that i might try myself but even if i dont perhaps these questions and their answers will be of help to others as well!
