Generally grooved is stronger less chance of cracking.

Why do you need them?  Just buy some good quality solid discs.

Some photos might help.

Back to the original question, did you mean grooved or drilled?  Slotted and grooved usually mean the same thing.

Grooves are OK, but can rumble through the pedal quite a lot if you've got a soft pad.

Drilled holes are pretty pointless tbh.

For a road car, a plain disc is probably the best all rounder.

Alright thanks for your help though   :drinking:

If plain discs are available in your size with the correct PCD and offset, I'd always opt for a plain surface, or grooves if doing track days.

They look in the 340mm size range, are they proper Brembo 2 piece discs, or solid steel jobs?   I've not see a Brembo senior kit.

Title: Re: Brake discs
Post by: rich83 on May 03, 2017, 09:51:44 am

That's not brembo senior it looks like the cupra setup so could be 323mm.

Title: Re: Brake discs
Post by: Shamm on May 03, 2017, 11:26:50 am

@pudding i doubt its the senior kit ill get it measured when i get a chance and update it on here
@rich83 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=709) i think you might be right

Good call. The bolt gives it away. Had these on a mk4.

OK cool.  Not sure where I got Brembo Senior from.  Must have been having a wet dream about brakes again.  Did I just say that out loud?

They're pretty damn similar. In fact, I think the LCR caliper is known as the 'Junior'.

As for brake porn...

Blimey!  They certainly look like 300kph+ brakes don't they!!  :surprised:

I found this video really interesting actually.  Stoptech factory tour.  They are an American AP Racing / Alcon equivalent.  Top stuff!
