Uwe Thanks for that - when my current (relatively) new EBC disks need replacing I might go down this route - a hell of a lot cheaper than the alternatives......
cheers

Martin,
just compare the first drawing with the second. In first the holes are circular, in the second drawing they are slot holes. I would say brakes are now adequate for the car. You want to brake, push the pedal. You want to brake more, push a little bit harder. Not like that "it doesn't matter how much harder i push nothing more happens" feeling from the stock brakes. I can lock the wheels with ease at 80mph. Ask Kevin And they didn't change at all, I did 4 lap runs with just the ticket machine as a break time inbetween. No fade, just pure braking pleasure Edited by UweM3 |

Hi Uwe Thanks for that - very useful having access to all that equipment for the mods. did not mean my comment from Grant to be a critiscm just an observation. When you say you are elongating the holes - what do you mean - does that mean the bolts could move about in a bigger hole? - you might have guessed I am not technically minded and if you had seen me changing my front brake pads at Silverstone you would have seen that this is indeed true How did they perform compared to the standard?

Martin,
hearing comments like Grant's is one of the reason I do not encourage people to copy what I do. I do not want to explain why I have done this and that and do not want to be held responsible if things do not work out as expected. I can assure you that I am not suicidal and take great care in what I am doing. I will of course explain to anyone interested what parts and work is invloved, but everybody is using this setup AT THEIR OWN RISK! The disk is indeed close to the tierod ball joint but I have already something in mind to protect the ball joint. But this is only because I have REMOVED the backing plates. If you leave the backing plates fitted, you need to bend them to clear the thicker disks and the ball joint will be as protected as before. So for anybody who wants to know: --You will need brake calipers from a E32 735/750 --the caliper bracket will need some minor milling --the disks are Mercedes W124 E500 (early model, 300mmx28) --disks need modification of the centre bore and the PCD. Thats all. can't advise on machine shop, I do most of the work myself. left Merc 500 disk, right BMW M3 disk Merc 500 disk (not machined yet) drawing for Merc disk modification elongating holes of Merc disk to suit PCD of 120 Red arrow shows the boss of the caliper bracket which needs to be milled flat Bracket milled flat another shot the caliper bracket does NOT sit at the very centre of the disk. I didn't fancy to mill more off the bracket. But as this is a sliding caliper it will make up for the difference which is less than 1mm. The red arrow indicated the area where you have to make sure it doesn't hit the disk. Edited by UweM3 |

Kev
Great photos and if you have any video of me on track it would be great. The chap in the MR2 remembered me passing him at T13 and we sort of got chatting. After a few high(ish) speed laps in the M3 I think he will be out looking for one to replace his MR2. The same applies to one of the passengers in the E39 M5, he was still nervous after incident so I took it gently but he was still impressed with how the M3 handles and kept quizzing me about costs. We are delighted with the engine and the airbox is so loud that Gill has taken to using ear plug even with her helmet on. Apparrently I need to as well to stop me shouting at everybody in the Grune Holle . Apart from the unfortunate incidents, primarily bikes, it was a great weekend with great people and yet again the R888's have surprised me gripping very well in the wet conditions. Uwe, we must find you a solid shell so you can get a cage installed... Cheers |

Awesome trip! Thanks to Stannard Motors
for re-building the engine. Thanks to AHMotorsport (Hartney Wintney) for
getting it to 235 bhp and spot on with the fueling, and thanks lads -
it was a good crack on and off the track.

A few screen shots from my DL90 datalogger showing bits of my last lap.
Pic 1 is at the very end of Breidscheid just before you turn right going up the hill into Exmühle. Very entertaining bend and one of my favorite Pic 2 at Kallenhard I hope all this maks some sort of sense as I am new to this software and haven't had a lot of time to play with it. The trackmarkers are also set by hand. So have mercy with me |

WOW - that's going some and on road tyres. Good to see you only pushed when you knew the car felt right!!! And you were thinking about scrapping it? Maybe it was the involuntary weight saving (rust) that gave you an edge as well A little bit more power? That's why all those porsches keep going off. What you need is a CSL like Steves' - awesome. The stickies should do the job next year. On similar subject, I went out and followed Kevin in his Cecotto and near the start of the circuit just before the long straight bit (yes, yes, yes will learn the bends eventually) a MR2 span out of control doing a couple of 360s in front of me and just behind Kevin? He was fine and kept it on the track but must have shaken him a bit. It was still damp I think. Anyway, Gill told me that Kevin later took him out as a passenger, not sure if he asked Kevin or if Kevin offered, but I thought it was good of Kevin to show him the lines etc - Kevin did just the same thing for me on my very first visit - top bloke. |

I know what you mean. After a few laps your brain adapts to the speed and you feel going "slower" as in the first two laps.
when we drove I didn't had a very good feedback from the tyres in the fast bits and had to lift of to save my underwear but as soon the pressure was raised I had suddenly some room left to the curbs coming out of the bends. Dan was with me in the car and felt the difference as well. Also there was NO traffic in front of us. Didn't had to lift off once. I checked the time of the run and the time is 527.68 sec = 8.47min Quite a few bends with constantly over 1g and the high peak going round Exmühle (didn't braka at all before turn in) with 1.4 Dan couldn't stop grinning in the passenger seat. I am very pleased how my car handles now. No understeer, no uncontrolable oversteer, brakes are fine. Just a little bit more power and....... Can't wait to get thoose stickies back on. |

Go on post your laptime. We all knew you were going great guns and we were very impressed, especially Roy, knowing we were on stickys and you were on road tyres for those couple of laps we all had together. This is a bit naughty I know but when I checked the vid timing from gantry to grantry, with Steve it was 8.49 min, and that was with some traffic. On a couple of clear laps, it was a bit quicker!!! - Roy and Richard well I just wonder. To be quite honest, it got to the point where I just stopped for the day, handed my remaining laps to someone else and just stopped. I could not TRUST myself anymore, do not get me wrong, I had no dodgy moments BUT it just got to that point where things were going too well ... if you know what I mean. Edited by rattusM3 |

Kev,
after our very entertaining group lap (thanks Keith ) I had a few more on my own. For the final two I raised the tyre pressure slightly and that really made a huge difference. I recorded the last two laps and manged a laptime I don't even dare to post. How does 1.2 to 1.4 g's round the bends on road tyres sound? And my DIY big brake conversion didn't let me down for a second during the whole weekend. |

Thanks for that Steve. May need to wait for the vid as I need to find the best place to host it as my last attempt was a bit of a disaster, any ideas especiall if over 100MB? We were all flying and improved tremendously. Not much in it between Roy, Richard and myself. Keith (the Rock Star) has improved which showed when I had a passenger lap with him, has become alot smoother with the lines. Mark, well he will be one to watch out for next year, not many laps under his belt but that will change and we will have to put cement in his boot, always knew how to drive well in the first place with lots of practise in his E30 2.7 touring. All in all excellent weekend, no incidents of note and even the rain did not stop the fun, just drove according to the conditions. A number of REALITY CHECKS during the 3 days: - That poor M5 - crickey - The M3 that hit the concrete at Adenau, that bloke has been Ringing for a long time and was very experienced BIG WARNING TO US ALL!!!!! - The biker who came off on the very last BEND, possible fatality as they did not open the track again after that. Still, lets not put a damper on things, it was still a great 3 days. Oh Uwe, what was it like shaking hands with a Rock Star and not even knowing it. I wonder how long I can milk this one for Keith. Small world regarding Norm and the crazy Porsche, Uwe, I knew he drove really fast Porsches but would love to see him do it. Kevin Edited by rattusM3 |
