with stock brakes? how long do the rotors last compared to the napa ones while using race brake pads?

Maineiac

I am. Just started using them this year. I have 4 days on them so far, using Wilwood H pads, and they are holding up well. NO cracks....yet.

I'm hoping they survive the remaining track days for this year (6).

Maineiac,

PLEASE POST FOLLOWUPS!

Seriously, I'd really love to settle this debate, AND know whether a two-piece is worth the $$$.

I know mileage may vary, but this would really be great to finally know.

Thanks!

I used the NAPA rotors on my Z06 for a few years, but kept cracking them....which kind of bothered me from a safety standpoint. Yes, I know everyone says they only crack while they are cooling down....but hell, that could be between sessions. Anyway....I wanted to try something different so I splurged on the Stoptech 2 piece Aerorotors. They claim to move 61% more air than stock rotors...that combined with my lovely spindle ducts ( ) should help them last throughout the summer. We'll see....I'm also using the Wilwood H pads, and I'm VERY impressed with the wear so far. 4 track days = 16 sessions...and they still look new.

They're not just better because they move more air, but because the 2-piece rotors allow the disc to expand and contract better.

I have one day on mine at Pocono long course with Wilwood SL-6 caliper and H pads. Forgot the mileage (125 miles before valve spring broke?) but will know tomorrow when I pick up the car. I see some crazing I'll know more on the 4th day of running when the NAPA's would be in the round file trashed by then.

Hey, John, you coming to Pocono Friday and/or Saturday?

My inspection is up so I don't think it would be considered street legal. Doubt I can get it inspected in time.

gonzalezfj

That's too bad John. We will miss you and the orange-tailed beast. My C6Z will have nobody to play with...

Hope you make the long course with PDA in Aug. July 15th on the North I have a wedding Greg will be there to play with

Ryan Are we thinking about tracking a new silver C6

RMilla17

nope. haha

I may be intersted in this just for PITA factor with napa's always cracking early.

If these lasted for 3 weekends or a set of pads or god forbid 2 without cracking threw then I may be interested.

yellow01

I'm pretty sure these are more expensive than 2 sets of Napas.

"If these lasted for 3 weekends or a set of pads or god forbid 2 without cracking threw then I may be interested."

Mine have already lasted more than that without cracking, but they are about $250 each.

ErnieN85

Mine are at 2 weekends although I'm not as fast so I'm not as hard on them. However the look almost like new. not enough wear to show.
Stoptech aero rotors when I bought them I was quoted $170 for the disks so if they hold up it'll be worth it to save the agrivation!

Z06 Silver Bullet

Yeah my time and labor in 100 degree heat at the track betwen run sessions is definetly worth some extra cost.

I normally get 12-15 sessions or so out of my rotors if they don't crack in session 2-5. So if I am lucky I change pads and rotors at same time.
Would love to change pads twice for each set of rotors.

Is that what you do with these rotors??

Are they also lighter weight I am guessing?

Where can I get the stock replacement size ones??

yellow01

So a set of Napas comes out to be $27*4 so let's say $110.
These are $170*4 plus tax ~$680

Realistically you'd have to add shipping. For me I'd add shipping for the s-techs but not napas as that's a local pickup for me.

Either way, they'd have to last ~ 6 times as long to be monetarily worth it - for a money only consideration.

This would drop a bit depending on how you value your labor switching out the Napas.

Even if you drop it to 5x, that's a lot of time compared to Napas. So if I can get two weekends out of Napa, that's 10 weekends out of a set of these. It would be great but I wonder if they'd come close?

I have no idea, just wondering.

"These are $170*4 plus tax ~$680"

Nope, I don't think that's correct. I would assume front rotors would last at least one season. However, I would assume that you would NEVER change rear Stoptech rotors. Perhaps Lou will weigh in on this.

yellow01

Fair enough. I change napa rears 2 to 3 times less often than I do the fronts so comparing 4 rotors to 4 rotors may not be the right comparison.

I dunno - shrug.
