Mtec v Mintex

[Darkside]

Just going to upgrade my brake discs and pads to dimpled and grooved but don't know which is better, so thought I would ask you guys?

[Commander]

There's nothing in it imho - it's more to do with who makes them and how. If they're cast with the dimples / grooves in, they tend to be stronger than ones that are drilled.

[Darkside]

Yes, I've heard that drilled can crack hence why I'm going for dimpled but didn't know if one was better than the other so thanks for that Commander

[The Bounty Bar Kid]

DBA discs are really good imo.

I am with Commander, you would be hard pushed to notice any definable difference, I am using mtecs and have given them a good work out on 2 track days so far and performance has been up to par with anything else I have used and there is no defects to note.

I've got mtech discs with mintex pads lol. win win.

MTEC discs on mine - drilled and grooved, with Ferodo Premier pads and Goodridge hoses..

Excellent feel and stopping power!

 

MTEC heat treat their discs after machining, so I'm not worried about cracking due to the drilled holes, and they do look better than dimples imo.

 

90% of the Mercedes in the car park at work have drilled discs on the front,and what do they know?

^^^ The joys of internet scaremongering.

Just to scare you even more, I spotted an Aston Martin DB9 today, and that had drilled discs on front and rear!

What do they know about stopping from high speeds?

Don't they use some exotic ceramic stuff to make them?

[GrahameJ]

The discs look like iron/steel, but the calipers look exotic ;-)

A quick google shows the discs are CCM Carbon Ceramic And yes those do look exotic

if the disc is cast with holes in it then it will be fine, no weaknesses are introduced. which will be how all aston, Mercedes, BMW msport discs will be made.

 

the problem comes when discs that are cast solid then have holes drilled into them, and are then subjected to high temps. I've seen a couple of cheap drilled discs develop cracks on track cars, so its definitely not just an internet myth.

[Commander]

Yup - I'm with Brillo - I've seen drilled mtech disks literally cracked in half due to the heat they've been subjected to.

[Jetpilot]

its definitely not just an internet myth.

 

Where did I say it was a myth?

 

I said it was scaremongering because somewhere, someone has read about a cracked disc. I have read people have bottom end failures on 350z, should I sell mine becuase they blow up?

[brillomaster]

i'm just saying consider your intended usage before buying - in general day to day driving i'm sure cheap drilled discs will be fine. But having seen the effect first hand on my own car, if you like spirited driving or trackdays especially, i'd spend a bit of extra money and get something reputable.

Performance Friction...

 

Drilled AND reputible...

 

TBA, yea ahd worry if ah was in a car lappin Knockhill like a was testin for Ron Dennis with a cheap Ebay disc coz, yea, things break when you drive like that...

 

Buy the best you can afford, forget about cracks, get on track, learn their limits and have belief doing it... Belief is everything...

Just fitted Mtec, yellow stuff and braided lines all round last weekend. Dreaded threading of both rear bleed screws though!

[Smc1992]

I have MTEC discs with brembo pads fitted and can't say I noticed anything special about them. Then the other day, under heavy braking, they started juddering like mad. About 5 minutes later they were back to normal. I have no idea why this happened (maybe the discs got too hot) but its put me off this setup and will be looking at different solutions. Just my experience with them, they have been fitted on the car around 2 months so far.
