I'm just in the process of putting on new rubber (Nitto 555's) and refinishing my salad shooters. I think I may have time and budget for one more upgrade before I get her out on the road for the year.
My brake system is currently 100% stock and I have no major complaints with it. I am looking at port and poilish for my next winters project - so I thought that a brake rebuild/upgrade might be a good idea first. I've read most of the threads on upgrades and am left with the impression that if I just rebuild the stock calipers, upgrade the lines to SS, upgrade the fluid, and the pads - I will get 90% of the gains for maybe 20% of the price of a the wholesale upgrade (e.g. C5 or C6 or aftermarket calipers+rotors). I was looking at the DRM spring upgrade - but doesn't seem to be a real benefit for street use. Appreciate any input on my line of thinking.... Glenn

I have upgraded brakes and love them. You may want to go to the C5 calipers as that is an improvement and fairly cheap.
I have the Baer 6S 6 piston system on my Z and the pedal feel and braking is incredible. Just depends on your budget. Also 6 piston won't work with alot of wheel combos. ![]() ![]() Last edited by xlr8nflorida; 02-07-2011 at 10:21 PM. |

I have a complete C5 brake upgrade for sale at $450. Rebuilt calipers, abutment brackets, and SS adapter brackets from PNW. The DRM spring is $12 from DRM.

That's some serious brake porn guys.....
I don't have a specific budget in mind. I'm looking at it more from a cost/benefit perspective. I'm willing to spend some $ if I can convince myself I'm going to really notice a difference. You can at least quantify engine upgrades (there is lots of HP Vs mod/$ data around) - brake upgrades are a pretty subjective topic it seems. There is some 60 to zero data available for stock which is interesting... C4 ZR-1 is about 125 feet, C5 Z06 is about 117 feet, C6 ZR1 is 97 feet. After reading dozens of threads on the subject over the weekend - I came to the conclusion in my original post. Dom, I'd love to be able to justify giving your C5 setup a new home, but I just haven't been able to find anything that convinces me, but I am definitely open to hearing any opinions/experiences out there. Some hard data would be even better

My white car has C5 brakes with Baer Eradispeed rotors S/S lines and the bias spring. Great improvement for the buck.

If you want to stop shorter, get stickier tires. Stock brakes with decent pads will easily engage ABS with street tires.

Carbotech might have a good street pad with non-corrosive brake dust. Hawk HPS might be good, but haven't tried them. I can mainly feel a difference with the DRM spring on the track when trailbraking into a turn, the backend doesn't jack up as much on hard braking and the car stays balanced better. With hard braking on the street it feels better also with the car staying more level. I like the bling from the newer calipers though. I would sure like to try those MovIt's !!

Stock ZR-1 brakes are plenty with the right pads. As has been pointed out, stickier tires will actually do more for decreasing braking distance. I've done plenty of road course track days in a 92 (LT1) with J55/ZR-1 brakes with no issues, and also had an 01 Z06 right after it to compare to. The only reasons I would think about upgrading would be for:
A) Looks B) Ease of pad change C) Stiffer caliper D) Bigger rotor (more heat sink for longer track sessions) All of the above would be addressed by a C5 upgrade for a reasonable price. Anything more than that, and you better be at the road course every freaking weekend of the year. ![]() |
