Default Stock Z51 Rotors vs Aftermarket?

Ok so I'm due for rotors on my 2014 Z51. I have experienced some brake fade on the track under full speed hot laps. My question is how much difference is there between the Z51 stock rotors w/ Hawk HPS plus pads and lets say a DBA 5000 Rotor w/same pads? We are talking quite a bit difference in price here.

I’m currently running the DBA 5000s on the front with the 650 pads and 4000 with the 650 pads.
from what I’ve seen the brakes stay cooler and if they start getting a little hot all I have to do is let off on one or 2 corners and they are back to normal. Compared to the stock pads and rotors, I’m actually glad I went that route even though it was more expensive, I should have gotten the 750 pads instead but the 650 are not too bad. I run my car at the GP and nordschleife in Germany

Lol. I wasn't sure. We don't have motorcycles and cars on the track at the same time with cars typically. Also you passed someone driving a station wagon. I haven't seen any station wagons on the track here. Looks like fun thanks for sharing!

Hawk HPS is not a track pad. Your problem is with the pad compound, NOT rotor.

My original pads and rotors are starting to give up, rotors are probably warped.

I am just about to mount my StopTech two piece rotors on my 2017 Z51 in Sweden, Europe. I will also install Carbotech XP 20 pads in the front and XP 12 in the rear. To make it complete I will also install stainless brakelines/hoses on all four corners to get a better feel in the pedal.

Here in Germany you pay 30€ and can drive whatever you want on the track as long as it’s road legal 😂 it really fun but it can make it a lot more dangerous as people who haven’t been to a track before get into the track and half of the time crash because of it. Anyways a good track pad and rotor will hold up way better than the stock stuff! Good luck with your purchases

Are you not willing to swap pads for street and track?

Rotors are not the issue its your pads.. You need a higher temp pad to prevent brake fade and DOT 4 fluid. Yes, the Dba rotors are far better than the stock 14 Z51 rotors.

Carbotech™ XP8™

A high torque brake compound with a wide operating temperature range of 200°F-1250°F+ (93°C to 676°C+). Carbotech™ XP8™ is the first of our racing compounds. Good initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance and very rotor friendly. Perfect for track day use with any tire and can still be driven safely to and from the track. Carbotech™ does NOT recommended XP8™ as a daily driven street pad due to elevated levels of dust and noise. Carbotech™ XP8™ is a great compound on the front & rear of most open wheel and sports racers.

Carbotech™ XP10™

When Carbotech™ unleashed the XP10™ to the general public it immediately gathered multiple regional, divisional, and national championships. The XP10™ has a very strong initial bite with a coefficient of friction and rotor friendliness unmatched in the industry. Fade resistance is in excess of 1475°F (801°C). XP10™ still maintains the highly praised release, excellent modulation and rotor friendliness that have made all Carbotech™ compounds so successful. Carbotech™ XP10™ is not recommended as a daily-driven street pad due to possible elevated levels of dust and noise.

Pad compound compatibility for street pads? Back and forth requires pad compatibility if you swap pads.

The great thing about Carbotech brake pads is all their compounds are compatible with each other. So, when going from the 1521(Street) to the XP series (Track) pads all you have to do is swap pads and go no re-bedding no cleaning of the rotors just swap pads and go. This also saves you the cost of having to get a separate set of rotors for track or street.
