Smike Posted October 13, 2012 Share Posted October 13, 2012 (edited) Just for other SN95 owners, if they are interested. Currently on the old CMC1 setup. 12in cutdown Cobra rotors with the caliper bracket adapters and Cobra calipers. Not that the pads are hard to get for the Cobra setup. 12in cutdown, to my knowledge, are - without a machine shop on hand. 12in 2003+ Crown Vic rotors are an option; however, with the allowance up to a 13in rotor, might as well use everything. Main complaint with the Cobra calipers is the pad design with the crown fitting that fits into the pistons. Here is what mine looked like after Road America: Crowns stuck/fused into piston and piston warped to point of full rebuild. There is an impedance somewhere in that setup that wears pads at an angle. Have 1/4in on one side of pad; backing plate on other. Has to be something better? Perhaps. 2008 Z51 bracket, C5 caliper and pads C5: Cobra: Bracket bolts nearly on without modification. Will need to bore out the lower slightly to account for 1mm difference in bracket bolt spacing. Otherwise, bolts for the Cobra will thread right into the Z28. Here is the pad and bracket on the 12in rotor. Note that coming up 0.5in with a 12.99 rotor will make it flush. Here is the Z28 held in place: Gets rid of the Corba pad style for the smooth backed backing plate of the Z28/C5. Likely will not be able to run 16in wheels after this. Will see once I get them bolting on more. Edited November 30, 2012 by Guest Quote Link to comment Share on other sites More sharing options...

Smike Posted October 14, 2012 Author Share Posted October 14, 2012 Nice, those should work better for you. Yeah. I think with the larger pistons and the pads not being apart of the pistons will make pad swaps easier and less uneven wearing. Quote Link to comment Share on other sites More sharing options...
cozog1548534733 Posted October 15, 2012 Share Posted October 15, 2012 Stoptech should be on the list in your future. I'm going for not spending $2100 on brakes. But you will on pads. Hawk DTC70 for the 4th gen calipers are $250 a pair, and only .5" thick. Pads for my wilwoods are $120/pr and are .8" thick. 1/2 the price, 60% more pad. Do the math and you'll justify a set of wilwood calipers easily for the cost of 1 years 4th gen pads. Just my $0.02... Quote Link to comment Share on other sites More sharing options...

However; on a personal level, I don't like only being able to run one pad or rotor. I do like being able to get over the counter parts for when you need to. Carbotechs are ~$220 for the C5 pad. Thicker than the 4th Gens. Pads, rotors, and calipers priced out to $405. Rotors are $120 a set for high carbon. And mine lasted me 5 weekends before RA ate them up. Rotor rings cost ~$250 for a set. Roughly double what a set of high carbons would cost me. Quote Link to comment Share on other sites More sharing options...
suck fumes1548534743 Posted October 15, 2012 Share Posted October 15, 2012 You can get any pad with stoptechs. All you do is call the company you like and tell them the part number on the brake kit. Even if they dont have it they can make it. I've used cobalt pads for years and when they didn't have a set that I wanted for one of our chump cars I sent them a backing plate off an old pad and they made a set for me. Not any more expensive to do that cause they just order them on the next batch order from the factory. Quote Link to comment Share on other sites More sharing options...
Smike Posted October 15, 2012 Author Share Posted October 15, 2012 My impression of CMC was that it was not about how much money you could spend on BBKs, suspension, engines...otherwise, I'd build this to be a top PTB car. Just was posting if any other SN95 driver wanted to do something with their brakes and did not want to spend $2000. $405 > $2000 Quote Link to comment Share on other sites More sharing options...

But it is still not a big money class. 2K for brakes is actually cheep. Just get the calipers then if you can find them. I run an autozone rotor. 41 bucks and I get free replacements!! or you can find a pair of used 2000 cobra r brembos. Which is what I did. The pad is a little more expensive but its basically over the counter parts still. Quote Link to comment Share on other sites More sharing options...
Smike Posted November 29, 2012 Author Share Posted November 29, 2012 13in Mach 1 rotors, Z51 Corvette brackets and C5 Caliper: 12in Cutdowns or Crown Vic rotors, C5 bracket and caliper: 12in option will require spacers to give the caliper more clearance. 13in fits nicely and the brake pad has good contact. Forces my hand to run 17in wheels only...at least up front. At the point of getting ready to fully install. Quote Link to comment Share on other sites More sharing options...

DrC Posted November 29, 2012 Share Posted November 29, 2012 This reminds me of when I was younger and would go to the junk yard and piece different parts together to make something work. Keep up the good work on keeping the cost down. Did you have to modify the Z51 Corvette brackets to make it work on the mustang? Also how is the Mach 1 rotors different form the Cobra 13†rotor? 13in Mach 1 rotors, Z51 Corvette brackets and C5 Caliper Quote Link to comment Share on other sites More sharing options...
Members Al F. Posted November 29, 2012 Members Share Posted November 29, 2012 Very nice! Now, you probably want to do some digging into how this change of caliper piston and rotor diameter is going to affect the overall brake balance of the car. You've increased piston size, which increases pad force for a given amount of brake line pressure. You've increased rotor size, which increases negative torque for a given amount of line pressure. Result? You've got a pile more front bias. Quote Link to comment Share on other sites More sharing options...

Also how is the Mach 1 rotors different form the Cobra 13†rotor? 13in Mach 1 rotors, Z51 Corvette brackets and C5 Caliper There is some flashing that I want to clean up from the caliper. 1 to 1.5mm worth that needs to come off with a hand file. Mach1 = Cobra rotor, sorry changing terms there. Very nice! Now, you probably want to do some digging into how this change of caliper piston and rotor diameter is going to affect the overall brake balance of the car. You've increased piston size, which increases pad force for a given amount of brake line pressure. You've increased rotor size, which increases negative torque for a given amount of line pressure. Result? You've got a pile more front bias. Thanks! Correct Al. Was doing the math here and came up with that "issue". I'll update the first post. Both pistons are 40mm now. Cobra and C5 us 40-40.5mm units. There was still an increase in mechanical leverage and pad to rotor surface change. I have a lot of room to tune my brake bias still. May have to change pad compound as well if I cannot tune enough rear bias. I don't think I will since the 13in is pretty common with us. Edit place holder: 14mm 2.00 pitch for Corvette caliper brackets. Quote Link to comment Share on other sites More sharing options...

ecronbach Posted February 12, 2013 Share Posted February 12, 2013 I am not sure why you would want to spend the energy on the modds. You can get a bracket set from Bear Brakes that allows you to run the c5-c6 calipers on cobra rotors. The braket is a Pin Guild bracket so the pads float instead of riding on the calipers like the ford set up. If I remember is was about $89 for the brackets, $110 for the calipers and $69 for the cobra rotors. Pads vairy allot but you can find some deals on the vette pads if you look. Good luck.

Good luck. ecronbach, if you look closely, it's similar without the Baer bracket (subbing in the z51 bracket instead). C5 caliper and cobra rotor... So I don't get the tone on energy spent. http://m.summitracing.com/parts/bae-4261059 And it's $1k for that kit. Quote Link to comment Share on other sites More sharing options...
Smike Posted March 4, 2013 Author Share Posted March 4, 2013 Huge thanks to DBA and Hawk for picking me up this season! DBA 13in Cobra 4000 series rotors: DBA 13in 5000 series 2pc (for PTB racing): Will be running DTC-70 pads up front. Quote Link to comment Share on other sites More sharing options...
DrC Posted March 5, 2013 Share Posted March 5, 2013 Where did you find the DBA Rotos and what was the Price if you don't mind me asking. I am running Centric Roto from Tire Rack for around $70 ea. So far no problems but looking to get a back-up set. Quote Link to comment Share on other sites More sharing options...

ecronbach Posted March 6, 2013 Share Posted March 6, 2013 Hey Sorry, I was not trying to throw you any attitude. I was trying to explain that I bought just the brackets from BAER. Again I can't find my recipt but it was under $100, Calipers and rotors were off the shelf from my local parts store and SS lines from summit. With the stock pads I was under $500 total. I'll put up some pictures when I have a chance but it looks exactly like yours. So if some one is not as handy the correct brackets are available. Thats all Quote Link to comment Share on other sites More sharing options...

Smike Posted March 8, 2013 Author Share Posted March 8, 2013 Scott -- correct. Its another method of understanding what your brakes are doing. I also use an IR gun and contact probe to get temperature readings. Important for picking the correct pad and ducting requirements (if needed).
