Hi

So I've now done there track days with 3 different setups in my 330i E90. Results:

1) Stock pads, stock discs - result = fade then massive vibration acter a few hard laps - vibration never went away

2) New yellowstuffs, new solid discs all round - result- no gade, but massive vibration after a few hard laps, vibration less pronounced over time but still very evident.

3) Same yellowstuffs, new drilled and grooved fronts only - result - no vibration - no fade, even after 10 laps smashing around Donnington

There you have it

Well well, this is good news. I really thought it was the yellowstuff on my car which was the issue, but did wonder if it would be the discs.
So, you'll have to tell me which discs in particular you got! I had my car in last week and put on PFC pads up front (at that point i thought it was yellowstuff which was rubbish) but have been looking for drilled discs as well.

You mentioned in my thread that an engineer was going along with you to install some ducting too. Did you have that done?

Cheers

Hi mate

Glad you spotted this thread ! I couldn't find the original.

I didn't go with the engineer in the end, so no ducting.

However I did smash hard on the brakes (wheels were black after) and no fade and no vibration!

I used MTEC discs.

Ok great, so all down to the discs, I was pulling my hair out wondering what to do so glad I spotted this!
Any idea why its made a difference? The drilled holes help heat escape more and prevent pad build up?
I will take a look at MTEC then, they make lots of different types it looks like. Also looking at Zimmermann sport discs which are just drilled. About the same price. I'll feedback as well how i find them.
Anymore track days coming up?

Does your 330 have 330mm or 348mm discs?

I have a set of the Zimmermann drilled discs (Front, rears are plain) paired with Brembo pads up front and ATE pads on the rear and I gave them a good beating last weekend with quite heavy braking whilst doing some hill climb type runs and also from high speed (150+), they held up really well if I'm honest, way better than I was expecting so I can +1 on the Zimms!

330

The mtecs I purchased were the grilled and drilled variety with a silver coating. They look outstanding to the extent a few people have commented.

I had them without coating last time and regretted it.

Can you remember where you purchased the discs from? Just realised both websites I was comparing are actually based in Germany (although they are making it look like they are in the UK).

Yeah sure, I got them from AutoDoc however, they are also based in Germany. took about a week for them to turn up and their comms aren't great but they were the best price by a good margin. Worth the wait if you're not in a mad hurry.

If I were to choose between the MTEC and Zimms, I would go for the Zimms because not only was the price broadly similar but the coating on the Zimms is a proper protective coating compared the the MTEC which are simply powder coated/painted (even the face of the disc!). I found this out when a friend of mine bought a set for his E60 535D and ended up with the paint melting all over the pads, calipers and generally making a bit of a mess. Seemed a bit of a cheap move compared to the Zimms.

BTW I just noticed that https://www.autodoc.co.uk/ has 23% off right now.

Considering they had better prices when I bought my discs and pads at 19% off, I'd probably jump all over the 23%!!

Thanks a lot. I should have read this earlier but I did order Zimmermann but from Cartechone for the exact same price today...think they are all in it together!
Unfortunately straight after, I read some recent reviews of theirs and they aren't great so right now just hoping i receive the order.
I did call them up and they said delivery would be one week as well. Just a bit cheeky that their websites all make them look as though they are UK based.

Update: Having a bad experience with Cartechone. Box arrived and it was torn apart, discs inside had broken through their box and were just loose inside. Oh, and they only posted 2 discs instead of 4 but they don't know what they've sent. Not impressed.
Now to get around their extremely slow and useless customer service

My 335i had Mtec discs on when I bought it. They were bloody awful. Badly corroded, the centre housing bit was cracked and they vibrated really badly when pushed hard on pedal. I wouldn't recommend. Go OEM or Zimmerman for discs.
