I'd say it belongs in the how to section, but the rear brake upgrade is a bit of a waste of money unless you get a proportioning valve and upgrade the calipers at the same time. Getting the brackets/rotor kit from bfr is what I'd recommend, you'd end up spending about 100 less and have the same stopping power. Unless you want the bling factor, that being drilled rotors are more for aesthetic appeal then anything as they actually do nothing but weaken the rotor and lowers thermal capacity. Slots don't do much anymore as they were designed back when pads produced gasses that needed to be vented off (much like cross drilled rotors) they do scrape away the top layer providing a cleaner surface, which in turn lowers pad life.


Overall tho, great write up man. Get this guy a contributor tag^^

^ True, I did do it for aesthetic reasons since it didn't look like I had rear brakes in the first place.

But, I disagree with your point on the drilled part of the rotors. If they did nothing ("that being drilled rotors are more for aesthetic appeal then anything as they actually do nothing but weaken the rotor and lowers thermal capacity"), why would Porsche, Lamborghini, Ferrari, Saleen Extremes, 05- 08 Roush Stage 3s, andFord GT have them?

Also, Iwould not recommend anyoneto purchase from BFR. The owner is a total D*ck and the business is atotal sham. If you have to return something to them..... It's sucks and you still get hit with a big charge.Had this happen to me twice! Had the guy also say that I was stealing parts when they were sending me the wrong crap in the first place. Also, they will fight you on the veterans discount too that the offer. They say they offer one, but do not back it up.

Lastly, theFord Racing rear cobra upgrade package requires you to remove the axle toinstall theirbrackets to holdthe calipers on. The Baer package does not! Which saves a ton of time. And the FR rotor is 11.65"s compared to the baer's 13" rotor. Also, why pay $200 for what you think are “upgraded” calipers. They only difference between the cobra and gt rear caliper is that the cobra is powder coated.

I guess you wouldn't likemy front brake setup either.

First, I'm sorry that buyfordracing has given you the run around, I havent had any problems when purchasing things through them, that is the only reason I would recommend them. But if you've had problems recently then I would advise others to be wary as well, times are rough and alot of aftermarket suppliers are tanking.




Now then, your argument that these companies car's using cross drilled rotorsin their supercars and therefore are performance related is a very flawed argument.

I'm not going to argue that these companies with super cars use slotted and drilled rotors, but I will say that the general public is much like you. The highend cars of the older era had slotted and drilled rotors because they ran bio pads that needed to be off gassed and deglazed regularly. Now everyone believesperformance and crossdrilled rotors go hand in hand.

A crossdrilled rotor is much more prone to cracking as they began their life as a plain rotor, only someone went and drilled holes into them, whether random or by "computerized special design" they should be seen as such. Holes in a plain rotor do nothing to help increase performance. It actually hampers it as it decreases surface area of the rotor (less pad contact area) and decreases its thermal capacity (as was stated above,less surface area = more heat retention, basicthermal dynamics). They also weaken the rotor itself as the holes, think of a perforation and how easy they are to tear along compared to a piece of paper.

Also goto a racing event, american iron or nascar, or hell look at a professionally built and engineered race car, not some pretty car tha rich people drive around and see what they are running.

I've had this debate before in several threads with several peopleand so far only 1 has ever had information contributed by another engineer (a family member that works for brembo) and not just the typical "but porche has it on their gt3" arguments.

https://mustangforums.com/m_4776929/tm.htm

If you're really adamant and believe truly that you've experienced a gain in performance then go post on corner-carvers.com (site with many suspension/brake engineers as well as drivers in many of the open trackings various series) and tell them your brakes are better due to the crossdrilled/slotted design of your rotors.They have been debating if there is any benefit to a slotted rotor for awhile, and if you have proof I'm sure they would shell out the extra bucks when it comes time to replacing their rotors(normally 1-3 events depending on which series it is)as it'll gain them valuable time.

Have a nice day, once again. The writeup itself has a lot of great information, the reason for a more expensive/drilled/slotted rotor is flawed. I'd recommend reading up on physics and thermal dynamics a bit, also metallurgy will also help with the understanding of how cross drilling weakens rotor.

^ After doing the research that i didn't do, you're correct about the drilled rotors and the dynamics behind braking. However, Baer does recomend there sloted rotors for racing.

Excellent write-up, and nice debate. I particularly enjoy the lack of personal attacks.

Question: This upgrade is very nice from a cosmetic point of view, and I understand that the functional improvement is questionable at best. But is this at all dangerous? If I were to [carefully] up the rears to 13" on stock calipers and do some autoXing or light road racing, would I risk some sort of cataclysmic rear brake failure?

Secondly, are Cobra brakes really the same as GT brakes? Would I have to go with a 'big brake' set (Brembo, Willwood, etc) to actually improve the rear brakes (outside of pads)?

Thanks, guys. Very informative thread.

I believe that all depend on the year of your car crewwolfy. For example, my 98gt came with 1 piston calipers... 99+ GT's and v6's came with 2 piston calipers. The new edges stop WAYYY better than my model. So yes, the upgrade is worth it in my case. Also, stainless steel brake lines are a good investment.

^1sloblckgtare you talking about the rear brakes? I assume you might be. The 99+ GT/V6/and cobra all have 1 piston PBR Rear brakes. And yes, Stanless steel brake lines are a great investment.

crewwolfyI don't think and from whatI have read, there is a potential for cataclysmic brake falure unless you are AutoXing everyweekend or running in Nascar or the 24 hours of lemans etc. For street use (to look pretty) and the ocasional Autoxing (1-2 x'sa year) should not causeyou to have any type of problem at all. From whatI feel, the upgrade definitely lowered the brakingdistance above stock andI doplan on measuring that eventually.

If you are a serious AutoXer,I would check out brembo, willwood,Saleen, or Roush's Alcon brakes. I was going to go with the Roush's Alcons (14' front and 13' back for $1,499 from stage 3)but I unfortunately have the only wheel combo that they will not work with. I would also steer away from the cheap Baer kits (Track day). PBR makes some of the calipers (Track day) Baer uses and PBR makes the calipers for Ford too. So basically, a cobra front brake system is the same as the Baer Track day, just with cobra on the caliper's side vs. Baer.


Also, if your looking for a rear upgrade and don't want drilled rotors, check out Steeda's rear upgrade. It has sloted rotor and and go for about $340.

After installing the 13" rotors, how much of a difference did you noticein stopping power between the stock GT rotors and the Baer rotors?

Honestly, just a little. The front brake upgrade that i did made a 100% difference. Whenever I have to make a quick stop in traffic, the car stops so quick I almost get rearended a lot.

I did the rear brakes due to the fact that the 18's made it look like I had no rear brakes.
