Brake upgrades
Without breaking the bank with Brembo or Baer brakes etc, is the cost of a C5 conversion kit worth the $$$ over slotted and drilled rotors with quality pads as a direct replacement for the original rotors?
Here is an example of the latter: https://www.ecklerscorvette.com/1988...ails_tab-title Sent from my SM-G955F using ZR-1 Net Registry mobile app

Re: Brake upgrades
J55s are pretty good, in a 1991 Test they did 155 ft from 70, thats with old tech tires and pads. A c7 corvette can pull it down from 70 in 130-135 feet with big Brembos.... so take a 91 Z with J55s add in good pads, bias spring, and new modern tires you are not far off pace... repeated stops or on the track you will see a difference but daily driving the J55s are nice.....

Re: Brake upgrades
Doug Rippie bias spring
Power Stop Z23 or Z26 pads Stainless brake flex lines High temp fluid Russell speed bleeders Master and calipers fresh Do a clean up cut on stock rotors 300 wear rating tires The engineers did a good job. You will surprise yourself what it can do on the street and on mountain roads. My practical nature says use stock to its maximum potential.

I would think upgraded rotors in combo with said parts would be even better than cleaned up stock ones..? https://www.powerstop.com/product/po...ior-brake-kit/ Sent from my SM-G955F using ZR-1 Net Registry mobile app

Re: Brake upgrades
Thumbs up for power stop Z26 drilled/slotted rotors plus matching pads. Following the recommendation of the brotherhood I upgraded my 30 years old stock brake system and it works great. No noise (I mean NO) and very little brake dust (yet more than on quality ATE Ceramic Pads). Brake dust is grey so you don't recognize it too much on argent wheels.
Brake force is good, yet the modulation can not keep up with modern cars to my opinion. You get what you pay for, i.e. heavy brake power will need heavy leg power as input, still. Neither is it as sensitive / giving good feedback like a modern brake. But the overall stopping power is great and does THE BEAST justice. Braided hoses probably improve the feel. They're on my list.
