J55 vs. C5 upgrade?
Been thinking about the C5 front rotor and caliper upgrade but already have the J55 option. Will there be a difference? Could I upgrade to a better pad and rotor combo on my current setup? I already have PF pads on the car but need new rotors. Would SS lines help?
Thanks for your input.

Stainless lines will definitely help! While you have it apart,

I got one of their brake bias springs and it works well also.
Even under hard braking, the nose dives less and the car stops flatter.
Well worth the 13 bucks for the spring. You might want to ask them how they put them in as it is a PITA, but well worth the time/cost/trouble.

I don't know about those pads you are running. Maybe a pad and lines upgrade with Syn Power fliuid would be all you need. I have J55's that are stock on mine and they are pretty good.

I did an upgrade to the J55 and it made a noticeable difference. Not sure how much better the C5 upgrade would be.
On the plus side the C5 pads are larger and the rotors are cheaper. It would seem that the C5 brakes would be better, given the larger pad surface.
On the negative side, you can't use the standard saw blade rims unless you use spacers.

IMO There probably isn't enough difference in the C5 combo than the J55 to warrent the cost.

I did my C5 upgrade on my 84 Z51 several years ago. I got a heck of a deal on lo mile C5 calipers and rotors. Along with my ZF-6 Transplant, it was the best upgrade I have done. Plus it was my excuse to put ZR-1 wheels on the car.

I've got AR TTII rims so I don't think space would be a problem. Maybe if I went back to my origional 12 slot directional rims but I like the look of the ARs too much.
So J55 is pretty good and I wouldn't get much of an increased bennefit? I think the SS lines sound like the best option for me. Maybe a good set of new rotors would help too. Any options there? Thanks!
Here's a pic of the wheels.

I switched the J55's on my '89 for C5 brakes. I wasn't unhappy with the brakes, but I got brand new C5 rotors, calipers, and caliper brackets for free so it ended up being cheaper than new pads and rotors for the J55's.
Outright stopping power isn't any better with the C5 parts, but the pedal feel is better because the calipers and brackets are stiffer. The only real advantage to doing the swap, IMO, is the fact that the rotors are quite a bit cheaper than J55 parts. If you do any track time with your car, this can potentially save you some money in the long run.

If you had 12" rotors like Dominic had on his '84, then the C5 brake upgrade would be great. Since the J55 and the C5 brakes both have 13" rotors, the benefit/$ would be negligible and there may be more complications.
IMHO, spend the money upgrading your shocks and/or sway bars for the best benefit!

Ceramic pads, new rotors, and SynPower work fine on mine. It took awhile to arrive at this combo (and I tried the PF pads, in my search for braking performance), but they can lock the wheels at will (ABS allowing, of course), and don't fade. What more could you want?
SS lines will not increase fade resistance or decrease stopping distances, but they will give you better pedal feel....which may help you perform better on the whoa pedal.

Tell me more about the Ceramic pads. No brake fade? That's great. What brand do you use? I won't be using the car for track events but maybe once a year.
I'd like a better brake feel and it would look pretty cool to have the SS lines on there.
As for suspension, I'd love to replace all the bushings with either new or polyurethane. I'd also like to lower the car.

I use SBS ProTouring Ceramic pads all around. I like 'em.
There are two types of brake fade: that caused by boiling fluid (soft pedal fade), and that caused by pads operating at temperatures beyond their design temps(hard pedal fade).
Uncontaminated brake fluid (e.g. SynPower or other high-performance fluid), changed regularly, will take care of the first issue. Proper choice of pads will take care of the second.
Remember; there is no one pad that is best for the street and best for the track....it's all a compromise. The ceramics are very good street pads and okay track pads (depending on the track, the car, driving styles, etc.), but if you want the best pad for your track, be prepared to experiment/research and to swap out pads and rotors for your track days.
This website has a wealth of information on performance brakes. I would suggest anyone interested in getting the most from their brakes read this site, cover-to-cover, so to speak....

No brake dust on my rims, NONE! Stopping power is fantastic (I call it my passenger eject system--PES) no pulling, no wet problems, and no fading. I do not autoX, so don't think I am recommending these for the track. I drive it hard as much as possible, but track use is something else.
