What do most of you do? I'm considering 12's all around or 12's front with 10's rear. For an 07 Z06, 570rwhp, R tires, coilovers, OEM hydraulics and duct cooling, DBA 4000 rotors etc. Mostly HPDE hard running. Noise/dust not a concern.

Most users seem to do the staggered set up.

On my C5 I always went square though. I would say you should experiment to see what you like.

R compounds should do well with 12/10. I would start with that to see how it feels.

For my 2 ton DD Camaro (ok, its a little short of 2 tons) I run XP8 square.
For street driving its a little noisy, but much better than the stock pads.
With the stock, high treadware rated, skinny tires I can mostly keep it right at the ABS threshold on the track.

On the track car I'm running xp12/10 and I like the balance.
If I can ever get my act together and put big brakes on the front I may try xp12 square.

Square. Always. Currently using XP10s with R888s. The books say that max braking occurs with the rear being slightly skitish, and less aware/experienced drivers tend to have too much front bias because it feels better. That being said, the C5 and up have the bias adjusted in real time by computer rather than a fixed setting proportioning valve. Does the mean that pad stagger will have less (no) effect on brake bias?

Have not tried them yet but carbotech recommended and I purchased xp20/xp10. I have 570rwhp, wilwoods, coilovers, r compound, etc.

I was using h pads square so looking to see what the difference is.

This is my question too, I would think ABS or the system might handle bias as needed. Anyone know????

Legacy Z06

Jumping on this one as I'll need pads. Bought a stock C5Z for track duty, will drive on the street to/from events and go for a drive every now and then. First year I plan on running Nitto NT05 tires street/track. Would XP8's all around work both on street/track or should I just go wiht 10's ? And what are they like on the street ? Any warmup required or simular to HP+ ? I'd call myself an intermediate skilled driver, tons of track days on other platforms , will be learning the C5Z next summer.

I've been using 20/10's for the last several track days on R6's. love the initial bite, even cold. They do generate a LOT of heat so keep an eye on your cooling, and boots if not already insulated.

On R compounds, 12/10 or 16/10 may work as well.

Depends a bit on tires both size and compound. (Also likely somewhat your amount of neg front camber) Street tires don't allow as much wgt transfer so square should be fine. I staggered brake pads last year with NT01 tires (square setup 315s all round) with XP10s up front and XP8s out back. Personally I didn't find it to be enough stagger.

A question for those with track experience, would a 10 square for a rookie on r888s be hard to drive? Should I start with a stagger till I gain some experience on track?

If OEM or mild suspension you'll have more weight transfer under braking and probably want staggered. It's the very firm/flat rides that might work with square it sounds like. Also see the link above your post.

Agreed. My stock C5Z on slicks was very skittish with square 10's. I was having a difficult time keeping the ABS from kicking in. Went back to 10/8 stagger and all is good. Might try square again once I get my T1 bars and shocks installed.

OK thanks
Now Im getting a set of slightly used 10 rears, can I start with 12-10 for my first track events?

With any stagger you will probably be fine, but the pedal feel may feel slightly different between the different combos. The 12/10 setup will most likely have more initial bite and require less pedal pressure than a 10/8 combo.

nolimits

based on most of the comments that seems to be what's experienced, also Carbotech mentions the 12s provide more. Per other posts note a lot of aggressive bite is not always best when getting started. Track driving is all about being smooth and keeping the car settled. Too much quick brake in the wrong place can get you. Something you can learn and enjoy though.

Good discussion, I'd still like to hear if anyone has used 12/12 on a well prepped car and what they thought ???

Adam@Amp'dAutosport.com

Yes.

JeremyGSU

I'm running the 12/10 combo and I think it works well. No complaints other than short pad life.

Stop using them so much They'll last longer
