Hi Guys, My local dealer Scottall, Watford, UK, has told me that my (stock, 2001, E39 M5) brakes are 'severely' corroded.
Time for BBK ! I will go with either a full Stoptech kit (front and rear) or AP Racing brakes - front only (as rears are not supplied).
I've done the searching already and want to pick up on the mood music from those in the know. I've had Roy at CA Automotive and Kevin Bird make persuasive cases for each - in the most helpful and constructive way
Which way would you go ? Thanks for your help as always and kind regards, Nik
Thanks GD,
I do still have the original 18' OEM rims and both parties are telling me that ABS and DFC aren't impacted - different from what the Board concluded a while back !
Love to buy the Brembo's, but I think they are expensive - more than U$ 12,500 + fitting for a full set in UK !
Kind regards, Nik
I changed my brakes in February this year. Standard M5 alloys. APracing BBK on the front axle (345*32 slotted discs), standard new BMW discs and Pagid pads on the rear axle plus uprated brake hoses and fluid (all supplied and fitted by Thorney Motorsport).
Have driven 7k miles on them ((including a 1,700 mile very high speed trip) and been very happy with the result, accordingly I'm not sure if it's worth the extra money going for a full rear axle BBK upgrade.

Don't bother with the rear unless you want the "look". I had the front Stoptech ST-40 and with a lot of track abuse it has never faded. I use PFC-01 pads on the track.

Same here. JCrist was the prior owner of my Stoptech ST-40s and he abused the hell out of them on the track and now I own them and have completed two track days with them using PFC-01 pads. It stops so fast it will suck your eyeballs out of your head. VIR has two straights where you brake from 140+mph and several from 90+mph and neither he or I have ever experienced any fade from them on the track.

Too much to list...
I'm coming to this thread a bit late, but maybe I can help. First, you didn't mention what you intend to do with the car - track requirements and I-want-to-make-it-look-better requirements are slightly different. I can speak to the track issues from experience.
Having lived with the M5 now for about six years and having tuned it for the track, here's how I'd figure this out.
First - decide about the rears. The stock rears are fine for track work, and with stainless lines you'll get good pedal feel and modulation. Use factory pads day to day, and PFC-01's for the track . The factory rear takes the same pad (and rotor) as the E46 M3, so there's a good choice of makes and materials.
If you decide to go for the BBK in the rear, then you need to assess your wheel strategy - many BBK's are too big (diameter or depth) for the stock rims to clear, so get ready for some knock-on issues. For Stoptech, Dave Zeckhausen's website has the best "what fits?" information.
The main point is that if you go to a rear BBK, you won't improve the braking but you might improve the looks.
Once you've figured out the rears, then decide on the fronts. If you are doing a 4-wheel BBK, then it's easy! If not, then I've used the Stoptechs for track work for four years and they're great! Perfect balance with the factory rears and easy to change pads. I suspect they're not the only setup that works this well, but my experience is that they're good. The best part is that stock rims fit just fine over them, including 17" snow-tire rims (Styles 66 and 49).
