Carbotech XP10 front XP8 back - my choice BUT
 

everything has a BUT.... (Beyond the underlying truth)
Either
Carbotech XP10 front XP8 back
or XP8 front and back...

But the real question should I go with them, since the car is driven on the street, to and from the track
or
should I simply just get street/track pad set

I want to replace the pads before the next track event in a month...

Thanks for being patience with me on this, at times I get all thumbs....
:tiphat:

I ran the same pads street and track. The squeal when cold on the street and they dust like mad. I didn't street the car much before the engine blew.

I use that combo all the time. :tup: Just be prepared for the dust, and the squeal coming to a stop. Neither of which bothers me. When cold, the pads still have LOTS of bite.

Ceramic coat your wheels and the dust should come right off

Love them on the track but I don’t think I’d tolerate them on the street to be honest. Aside from noise and dust they’re a bit much grab in stop and go traffic. I do the 1521 on street and swap to xp10/8 a week or two before events. It’s a bit a hassle but worth it in the end.

I've done 10/8 on the street for a couple years now, though it's more like 25% street.

If you are only occasionally tracking, consider swapping to 12/10 at the track and a nice streetfriendly compound most the time. If you have space to work and basic tools, the akebono's are quick to do a pad swap.

I ran the Carbotech XP10 front and XP8 back for years before switching to different brake pads. There is a reason the Carbotech brake pads cost more they bit really well and you will be able to see the full benefits of the Carbotech’s on the track. You will see a braking improvement with the Carbotech’s but you will need to run upgraded rotors though. Only con’s is you will notice is more dusting coming from them and evident on your wheels. Also when they are cold a specially on cold days they will make noise moaning etc. When they warm up they quiet down. One thing to realize is when running a track oriented brake pad like the Carbotech’s or similar rotor life will decrease some. I recommend switching from street brake pads when you want to drive your Z on the street and on your track days switching over to your track pads you will thank yourself later. The 1521 Carbotech’s will be a nice improvement on the street. What brake fluid do you plan on using? What is your brake set up plans for street/track?

Motol 660 brake fluid
Stillen Brake Cooling installed already
I did the Z1 370z(Sport) Brake Upgrade Kit a couple of years ago...

I street the car maybe third of the time. So sounds like I should be good.
Thanks all for the help

Should ask this up front, which suppliers do you use?
Since I have to get them by May 12th

I use myself, and am about to order a set from them directly. PM me and I can get you in on that order.

I would refrain ordering anything from Z1 in my opinion there are a lot of vendors you can order from how deserve your business. I ordered all my brake pads and brake related items direct from Carbotech and I'm happy I did. www.ctbrakes.com

thanks for the tip, found out they have a 10% discount for SCCA a members

I've been using the Stoptech sport pads for several years and over 20 events. I typically change fronts after every other event & rears every 3-4th event (all depending on track and duration). I know there are better track pads; but I've never had an issue with any kind of fade or stopping force. Hopefully I will eventually when I become a much faster driver. Best thing is that I can use these for street as well without squeal or significant brake dust.

I suggest you give them a try and only go to a harder pad when you find that you need it.

LMAO, if you are changing pads that often you need change to something else. Those pads are fine for street and maybe a novice at the track but not for anyone in this thread.:tiphat:

:iagree:

Replacing brakes pads every other event is a sign that you need to move to a harder brake pad compound for your track use.
