Not true Tommy.

Look at how the 99 - 04 GT brakes are compared to the 94 - 98. They went to the PBR calipers of the Cobra on the same size GT rotors. Why? Larger brake pads dont heat up as quickly as the smaller brake pads. Thats why Fox fronts dont fade as quickly as the 94 - 98 fronts do.

You can only lean the rears so much with out ABS before they lock up and that would throw you into a tail spin. If the rear locks up before the fronts do the car will want to spin around backwards. I had a 76 Cougar that had F'd up brakes like that and once in the rain I had a bad experience like that. Scared the hell out of me. Keeping the majority of the stopping power on the front wheels keeps the car stable.

I will be upgrading my brakes, I dont think the stock fronts will be enough to slow the car down from my intended speeds,.. but I will be keeping the rear as drums. I will not be converting to rear discs on my car right away. Well,.. its not an immediate plan. And if I do convert to rear discs,.. it will more then likely be for bling then for any other reason. I plan to use the front spindles, 13" rotors and PBR calipers from my wife's 96 Cobra on the front of my 93. That should offer plenty of stopping power for me to slow down from my intended trap speeds. I seriously doubt I will have discs on the rear because I need them. I would have them because I want them. I not going to say I will never convert to discs. I cant have you 3 yrs from now telling me,.. See I told you so,.. LoL

Woah woah woah guys calm down lol. I just needed to find the correct bs to get the right figment I was looking for. I'm not upgrading to disks because of the stopping, I only have this rear because I got it at a fair price. I already knew the coupe pictured had a stock width rear and that the rear isn't going to give me the stance like him, I know that's all in suspension but I needed to know the correct bs to give me the right fitment so that I can achieve that stance without my tires sticking out beyond the fenders. Looks like I'm just going to get rid of this rear and do what I was originally planning and just use ranger axles and sn95 spindles.... Anyone interested in the rear before it hits eBay?

 

i agree with you. i have did this swap and there is no comparing the fox drum brakes to the four wheel disc.i swaped all s/n brakes all the way around.lighter car with better brakes stops faster.

 

Noone is getting excited.....you have your answer, now we hijacked you thread . We can agree to disagree

 

I though you was building a healthy turbo car....What are you intending to trap mph?

 

Maybe I can help you guys compare on your own.

Take a 94 - 98 Mustang GT. Find a stretch of highway thats safe. Take it up to 120mph and stand on the brake until you slow down to 45 or so. And I mean stand on them like a freight train was crossing the road and your life depended on it. Then immediately take it back up to 120mph and stand on the brakes a second time and take it down to 45 or so. On the second hit you should experience some pretty bad brake fade. If you try it a 3rd time,.. you'll find yourself with half the pedal you had when they were cold and it may fall to the floor completely so be warned.

Now,.. do the same with a 87 - 93 5.0 car. To make this comparison fare,.. the 5.0 car must have good rotors with less then 80k miles on them. Not one with 200k on paper thin rotors with a half failing brake system with swollen soft lines and leaking calipers etc etc. Do it with an open mind and dont set up the Fox for failure from the start.

The 87 - 93 should make it the 2nd time with minimal brake fade. On the 3rd it will experience some moderate brake fade,.. about as much as the SN95 would on the second stab.

That same kind of braking is whats done at Sebring on the back straight into turn 17,... then up the front into turn 1 and then into turn 3. Very fast track that can be brutal on brakes.

Anywhere between 140 - 165,.. give or take. What ever 900 - 1000hp in a 3100lb car traps. Thats the goal anyway. Still only a wet dream right now.

Cobra brakes on the front with drums in the rear should be fine. My wife and I were coming back from Orlando on I4 in her 96 Cobra and a guy I knew had his Honda CBR 750 out. We were playing around and while I was trying to keep up with him we were cresting a bridge at about 160mph and the radar detector went ballistic so I stood on the brakes hard. State trooper was down in the median hiding. I got it slowed down in time. No issues at all. My buddy went ripping by him,.. didnt even slow down and the Trooper never went after him. Go figure,.. but I bet if I didnt slow down he would have come after me for sure. But those same brakes with ceramic pads will be on the front of my 93. Also my car should be 200 - 300 lbs lighter in race trim then her car was,.. so I'm hoping I should be fine. If it turns out that I need more brake in the rear I'll be the first one to come on and man up and say I was wrong. But so far I dont think will.

And Miles.. relax dude. Next technical thread I make,.. you have full permission to hijack it. Its all good.

 

Making a call to all aftermarket brake companies.......tell them to quit selling rear disc set-ups for Fox's......Verdict is in Hurst says they are not necessaary for brake performance....only for bling

 

We have about the same goals.....And my life will not depend on stock drum brakes

 

Your going overboard. You know why people buy rear disk brakes. Look at all the Brembo brakes on stock cars. You think they NEED a $3800 brake package on a 6 cylinder Chrysler 300? Come on.

My life wont depend on drum brakes either. It will depend on some nice big 13" vented rotors with twin piston PBR calipers and German made ceramic pads and the brake system will have DOT 5 fluid in it. The rear drums will be fine. It will even pass safety tech inspection at any track in the US.
