Exclamation Spa Trackday: BIBLICAL FL brake failure (Glowing Disc!)

Today was a perfect day @ Spa with the BMW Circuit Club.

Normally it's always raining @ spa but not today, and it wasn't busy!

I fitted my M3 with Toyo R888 245/265 19''. And didn't expect much from the tires but i was really surprised. Nothing beats sliks. But they lasted...and you can save 'em by keeping the steering angle low. Power down was great. I recommend these tires.

As a precaution i fab-ed some brake ducts - DIY Here -, upgraded the brake system with carbon composite pads, new OEM discs and SRF oil.

Should be enough on a car you already payed 145.000 Euro's for...(in Holland, Taxes don't ask...)

After a nice mornin' of abusing my M3, shown here in this vid: (Coming Soon)

The brakes where going down and suddenly were gone...I missed the corner, but luckily there was some runoff. I pulled in to pitlane.
This is a photographic evidence and proof that: ' THE BRAKES ON THE BMW M3 SUCK!!!!! The are SHIT!...As a professional race car driver i give them a beating. But i recommend everybody to change the stock brakes to a BBK.

C 4 ur selfe! Again excuse my Iphone picas....

Yes that's right! A glowing super hot LF brake disk, Like on a F1, IRL and DTM car.

After a while i turned the discs with a screw driver. The glowing part is where the pads where.

You undo the caliper by loosening these 2 screws. The plastic cap are melted.

Upon disassembly the brake like BROKE OUT OF THE FITTING!

The chain of event that led to these never seen before events are:

- BMW engineers design and fit the BMW with SHIT brake system.
- Customer that expects performance buy's a M3.
- Customer upgrades stock brake system to be ahead of the game.
- Customer drives the car on track, and it's ok for half a day.
- Brake pads wear.
- Heat get's to much for the !SINGLE! piston in the caliper.
- Rubbers burn piston get's stuck.
- Heat burns the pain the caliper.
- Brake line blisters.
- Brake disc glows up nice and red
- Brakes distroid
- Unhappy customer, spending even more money on his car that should have been fitted with proper brake in the first place.

I drove home in an E30 325 and my M3 was on the trailer.
Felt kinda strange leaving the track in somebody else's car with mine broken.

I'll be in Vegas for the 9th till the 16th of November. Anybody wanna do me an offer on a BBK? PM me.
