E46 M3 - Brake upgrade thoughts please :)

[jjcodex]

Hi all

I am looking into various big brake upgrades for the E46 M3.

I particularly like the look of the AP and the Brembo, but the Stoptechs are significantly more economic!

Anybody got any experience, and what size etc is the general consensus?

The car does track work reasonably regularly

Based on my experience, that will be okay, but the M3s on my trip all suffered from warped discs.

That said, mechanical sympathy is not high on the list of issues.

Hope not to hi-jack your thread but..

I'm considering buying an E46 M3.. I've just sold my track day car (Audi turbo Elise) but I'd like to do 'ring trips in the M3.

I'm not out to set records but obviously being able to stop is pretty high on my list of priorities. Would a combo of pads, fluid and braided lines make the car fit for purpose?

Probably just pad deposits, not warped disks.

sadly not so, they were checked with a run out gauge on a laithe, and also a thin layer was taken off to double confirm, and the wheel wobble remained. New discs resolved instantly.
