gobble said:DE events. I'm starting to think already that this poll was a bad idea.
VBNSX said:haha.. funny..
question is though.. are you trying to determine whether or not you want to upgrade your brakes?
From my standpoint I really think it's a matter of $$$..
Although I choose not to use the carbotech XP8/9/10 b/c the PP's give me more than enough stopping power w/ oem tires..
are you running r compounds?

nsxtasy said:Since the question is between "stock brakes" and "big brakes", I assume it's really about how you feel about different brake caliper setups, allowing for the use of whatever pads and rotors and fluid you want. If that is correct, then the four choices are really:
- With good pads and fluid, the stock brake calipers are up to the job
- The stock brake calipers are OK, but big brake calipers are in my future
- Big brake calipers are great, but an unnecessary cost
- Big brake calipers are the only way to go
I agree. Unfortunately, the fact that this poll appears in the Track and Race Reports forum makes it likely to be biased towards those using their cars primarily for the latter.kenjiMR said:for occasional DE events, stock brakes with good pads are fine.
For racing and time trials, big brake options are the way to go...

gobble said:Ya. Thats what I meant to ask.
Hrant said:As an FYI, and if I am not mistaken, last year DAL Racing ran on OEM pre 97 brake calipers.
HTH-YMMV.

robfenn said:Basically, if you get some racing pads and change the fluid the stock brakes will go on for ever...there is no need to get bigger brakes. But, it's clear the NSX brakes stopping power is nothing beyond average (although i think they have great feel) which is why a 6 pot kit is imminent.

The rotors don't warp, but they can develop uneven deposits of brake pad material that cause the brakes to shudder. (You can tell the difference because warped rotors shudder at all temperatures, whereas uneven deposits only cause shudder when the rotors get hot.) You can avoid this by bedding your pads properly. You can read more about this here and here.Edgemts said:I could not get a day out of any pre 97 set-up.
Cryo- rotors- race pads etc, extra cooling, rotors were trash at the end of one hard track day. tried several combos, all the rotor warped.

Yes: Experience. Mine and that of other owners I've spoken with. No shudder when the brakes are cold, in normal street driving; only when they heat up on the track, or when doing very hard braking on the highway (e.g. fairly hard braking from 70 mph to 30 mph). However, I don't have it any more (see below).Chris F said:Do you have a source to back up this particular claim, that rotors with uneven deposits only shudder when the rotors get hot?
If you were experiencing shudder as bad, or worse, when cold, then your shudder is different from mine. I used to have shudder develop after 3-4 track events, and it would go away when I replaced the front rotors. But they never shuddered when the brakes were cold, only when they were hot - which is the same as other NSX owners I've spoken with (other than you). Once I added some ducting and properly bedded my pads, I haven't been having any shudder problems. I can only say that your experience is different from mine, and that I've never had warping as you've described it. Then again, I'm still checking things out, after 9,896 actual track miles on my NSX. I've got another couple track events coming up; I'll let you know if anything changes.Edgemts said:the other thing is that warped rotors are usually worse when they are cold as they lose there shape from the heating/cooling process, when they are hot they are more willing move a little and go closer to there original shape, once heated again they get worse and worse.
