Aftermarket disks for stock brakes

I'm getting another set of the stock ones afterall.

The guy with the Stoptechs has been ignoring me. It's not like i wasnt happy with the stock items, i just wanted to try something different and i also really like the grooved look. Oh well. In a few years time then. :D
 
Stock ones, which are ATE if I'm right, are very good and cheap. I saw front ones at 103€ (92£) each, including VAT, in a french online shop : http://www.webdealauto.com/fr/Disque+de+frein+Unitaire/BMW+Z4+Coupe+3+2+M.19909.300020/1.price.asc.html .
 
no doubting the stock brakes are NOT left down by the rotors which seem to be really good quality, as ive had a set in my hands during my AP swap i can honestly say they were of real quality..... Its the single piston sliding caliper thats the let down...... Even then i found them great until the extremes of use.

i was sprised to see the 1m has 365mm front rotors, thats larger than the AP replacements for our cars.
 
Someone once told me that you will see very little difference in braking performance by jsut swapping out the disks and that the disks offered by brembo and the like are pretty much a con. At the time I was looking at getting the QS I owned ready for track use but didnt have the £2500 to hand for the AP upgrade. The advice he gave was to upgrade the pads/fluids and then save for the AP upgrade.

The stock discs are as good as it gets... Have seen plenty of race cars at the Ring use them with either "Big Reds" or "Big Reds" off a 997 Turbo.

More often than not it is all down to poor driving technique, where drivers spend far too much time on the brakes. As simple as that...

You're right they are very well designed and as i already said i was perfectly happy with them, i just wanted a change, not for performance but for looks, of course i wouldnt put looks over performance though.
 
Stock brakes with endurance racing pads (Pagid RS29 for me, now on 4 corners) are nearly sufficient on the Nurburgring Nordschleife, a fast track were brakes can be cooled...
However on smaller tracks, where you spend more time on the brakes (whatever your braking technic) and/or where speed are a way slower (so there is not enough air flow to cool the brakes), you'll need a big brake kit, for sure. If it's not the case, that is because you are in a "sunday stroll" mode :lol:.

I still maintain that the stock disc size and fully floating construction is more than adequate... The Ring has only got 7 places where you use the brakes hard and out of these only 2 places where you actually brake for your life... So if Pagid RS29 are nearly sufficient for you, then you are not going fast enough, simple as that... :poke:

I fitted 4-pot Brembos on mine all round as I like the better modulation that they offer, but the discs remained stock as they are perfectly fine...
 
I was talking about the full stock brakes (calipers included, not only discs ;) ), but with racing pads. Sure that with better calipers the stock brake discs will be more than sufficient on the Ring (but maybe not on some other tracks).

This week-end I had again some brake fading, but I don't think I was going so slow :D, I will post a video this evening ;).
