lakefxgp96 Posted May 15, 2007 Report Share Posted May 15, 2007 Does anyone know of someone putting together larger rotor/brake combos these days? I tried to get something together with F-body brakes but i see no way that they could work without extensive modification to the rotor and a specific caliper adapter. So even if you had to spend a grand, who would produce a larger brake rotor combo out there, like RSM used to? Quote Link to comment Share on other sites More sharing options...
jeremy Posted May 15, 2007 Report Share Posted May 15, 2007 someone was selling a high dollar custom made brake set in the F/S section a while ago Quote Link to comment Share on other sites More sharing options...

lakefxgp96 Posted May 15, 2007 Author Report Share Posted May 15, 2007 ouch. (careful what i ask for, right? lol) i was hoping for a whole set of 4 for under $2000 grand and thought that was reasonable! i'm just thinking about something like a conversion kit for an existing set of brakes out there. but thats neat there is (was?) a company trying to make some. I thought the old RSM ones were pricey, this is just OUCH. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted May 15, 2007 Report Share Posted May 15, 2007 Wasnt there a thread around here somewhere saying that you could use the brakes off a vette ( I think like a C5 but dont woute me ) and you could use those without too awful much trouble? Ill try to find that thread somewhere in this section Quote Link to comment Share on other sites More sharing options...

lakefxgp96 Posted May 15, 2007 Author Report Share Posted May 15, 2007 Heres a couple threads dealing with bigger/better brakes http://www.w-body.com/forum/index.php/topic,35936.0.html http://www.w-body.com/forum/index.php/topic,45782.0.html yeah i was involved on both of those. THeres a lot of talk, no doers. There was a lot of talk that f-body brakes would work, they don't even come close from what i can tell. So.. Questions to answer here are...if i install c5 brakes, i would need to drill holes, but will the rotor clear the knuckle without spacers? Is the caliper bracket a direct bolt on? does it need an adapter? or a special caliper bracket? Supposedly this was the setup RSM had, does anyone have any insight to these? I really think there is an answer staring us in the face if we are willing to pony up and try it. My biggest concern is, why would i buy a bunch of C5 brake parts if they don't fit without additional parts that don't exist, or require designing when i don't know of anyone with the equipment or expertise to design it? ZZP has been open to such ventures, i would just need to show them what to do....but what do i tell them? ? ? Anyway....theres about 256 threads on w-body.com talking about bigger brakes and every thread ends the same way... partial info, no real attempts, resources, or data. We had a great thread on making coil overs, why not a rotor upgrade? I still believe that the 'best/cheap way' to upgrade is to find something bigger for the front, and adapt the current fronts to the rear somehow....

lakefxgp96 Posted May 15, 2007 Author Report Share Posted May 15, 2007 IF anybody has specs on the C5 kit RSM sold, some high quality images...i bet anything i could get ZZP to make them. It's surprising how open they are to making parts for us, we would just need to tell them what to make and they will price it to make some cash out of the deal. If all we got was an adapter kit, that would be HUGE news. just buy a set of rotors and calipers any way you want to. So who wants to help me get specs and info?, pics??

jeremy Posted May 15, 2007 Report Share Posted May 15, 2007 ouch. (careful what i ask for, right? lol) as fast yours goes in the 1/4 you definitely need a brake upgrade Quote Link to comment Share on other sites More sharing options...
GP1138 Posted May 15, 2007 Report Share Posted May 15, 2007 adapt the current fronts to the rear somehow.... Would that be effective? I was under the impression that the loss of hydraulic force because of the length from the booster to the brakes were the reason that the rear brakes were ineffective, the front brakes do the majority of the stopping. Obviously, the rear calipers are shitty design though. Is there a loss of braking power because of the length of the brake lines to the back? Does anyone know what I mean, or am I making no sense?

mfewtrail Posted May 16, 2007 Report Share Posted May 16, 2007 IF anybody has specs on the C5 kit RSM sold The RSM kit used C4 parts. Jon("Pocket Rocket") on the 60*V6 board had the RSM(I think) kit on one of his Z34's. I don't recall him posting over there in a long time though. I believe Ben(Sappy!) lives near him, so he probably knows how to get in touch with him... EDIT: I think Jon had to run 17'' diameter wheels to clear the brakes. I would eventually like to upgrade the brakes on my '93, but I want to be able to run a stock 16'' diameter wheels... Quote Link to comment Share on other sites More sharing options...

Obviously, the rear calipers are shitty design though. Is there a loss of braking power because of the length of the brake lines to the back? Does anyone know what I mean, or am I making no sense? the length of the brake likes doesn't matter. the lines dont expand enough to make a difference and there's no air in the lines. The front brakes do a majority of the stopping due to the fact that most of the weight is up there. A w-body with properly functioning brakes doesn't nosedive very hard or have pre-mature rear wheel lockup even without abs. The 94+ rears seem to be about the proper size and the 95+ fronts seem to be as well. I firmly believe that the cars just need some slightly larger front pistons and a bigger master cylinder and they'd stop great. There's no way opposed piston calipers fit on these cars, which is kind of a shame. Quote Link to comment Share on other sites More sharing options...
pwmin Posted May 16, 2007 Report Share Posted May 16, 2007 the C5 calipers will bolt up to the 12" 2nd gen brakes, so it wouldnt be any diff than adapting f-body brakes, except you need bigger wheels to use those calipers or grind down the cooling fins, but then there isnt much point in using them then. iirc the f-body calipers can be had for $50 reman and the C5 ones are $100 from advance Quote Link to comment Share on other sites More sharing options...
luminal67 Posted May 16, 2007 Report Share Posted May 16, 2007 I saw a set on a 98-99 Monte Carlo at the 05' MGM. He had Willwood calipers and slotted or drilled rotors. Very sexy looking. I know that you were there lakeFX (sorry i forgot your real name ). It was red and extremely clean. Had an L67 swap and a ton of custom work under the hood. Someone had got to have some pics of that car somewhere. Good luck in your search though, I will b very interested in a set if/when you get one together.

GutlessSupreme Posted May 16, 2007 Report Share Posted May 16, 2007 Ok, so after you get C5/whatever calipers bolted up, with an adaptor or by whatever means necessary, here's my question: where do you find rotors? I guess they could be custom made, but to me custom rotors that you can only buy from one place at some ginormous price isn't practical. The problem is finding an existing rotor that shares our bolt pattern but also matches the diameter and thickness profile we're looking for. Has anyone looked at Mustang parts? Their bolt pattern is like 5x114.3 or something, isn't it? ours is 5x115 before everyone starts asking. Quote Link to comment Share on other sites More sharing options...
