Installing ATS Brembos on the Cobra.

[Blkkbgt]

Some folks can't make new lines. I admit though that the adapters in this case prob wouldn't work as the original lines bolt into the bottom of the MC so there likely isn't enough length to come up alongside, bend a clean 90* turn, and use adapters. In fact, now that I think about it more, it likely won't work at all. Looks like you need to make new lines

Ok now I understand where you were going.

I also don't see how you could get around not making new lines unless the V6 lines will work.

I say this because yesterday I was at pick and pull, while sniping electrical connectors in the engine bay of a V6 i noticed the MC lines came out of the passenger side and not the bottom. You can google the V6 engine bay and clearly see the lines as well.

I dont know what the line and fitting sizes are on those cars but I think its at least worth looking into.

IIRC, they are still 10mm or 12mm bubble fittings. SO an adapter would still be needed.

Don't they have short lengths of adapter tubing at all of the major auto parts stores? Bubble on one end double flare on the other, etc. I've usually been able to find what I need without having to use adapters or make new lines, at least for the MC side of things.

Installing ATS Brembos on the 2003 Cobra

Comparing this chart with MM's the 00R with 11.65 rotors and 38MM rear calipers is off by about 3%. Now if they made a mistake and used the GT rotor it would be correct.

According to that chart the bias is 74/26 with the stock 38MM rear caliper which from what I understand is borderline acceptable with max being 75/25. Considering Stop Tech shifts the bias around or slightly below 70/30 I wonder if the ATS calipers with 43MM rears would give the best braking performance?

Bringing this thread back up because I have some questions about the XTS setup that may be able to help some people considering it. The questions are a little redundant but I think its good to get as much info out there as possible.

I did a test fit of the XTS calipers this weekend so I can answer that for you.

Stock Cobra Brakes with stock 17" 03/04 Cobra wheel:
View attachment 1631254

14" GT500 rotor with XTS Brembo caliper
View attachment 1631255

The GT500 brakes are HUGE behind that 18" Saleen wheel. The calipers BARELY clear the barrel and do touch the face of the rotor though I have not milled the ears down 2mm yet. Placement of wheel weight may need to be......creative.

Have you been able to complete this mod and get the caliper centered over the rotor?

Do you have the inside barrel measurement of you 18in. Saleens?

How close exactly is the caliper to the barrel?

How is your pad overhang and do you have any pictures?

Wrapped up my ATS to XTS swap. I added a pic of the area that needs to be filed down for caliper to spindle clearance. I used the OEM brembo pads. So far so good. I haven’t really gotten on it as I want to bed the pad in properly.

What wheels are you running and how do they clear the barrel?

Have you been able to do any really hard stops yet and how does it feel?

How is your pad overhang and do you have any pictures?


To go along with all of this and not directed it at anyone above but has anyone checked the bias calculation with this 14in. setup? I assume the 43mm rear caliper is needed even more so in this situation.

By my math the weight difference between the ATS setup and the XTS setup is roughly 8 lbs per side with 6 of those lbs coming from the rotor. This brings the total weight gain to 16 lbs of un-sprung weight to the front end with the XTS setup when compared to the ATS setup (29.9 vs 37.9). The stock cobra setup weighs in at roughly 27.5 lbs by comparison. That's a pretty big penalty to pay and I am not sure how the increased braking performance and resistance to fade pans out in the end.

Just to put some info out there for anyone considering the XTS setup and happen to be running 18in FR500s.

I measured the inside of the barrel right off the face of the rotor on my car. At that particular point the inside of the barrel is roughly 15 7/8 inches. I am not sure it that will clear the calipers. Judging by what little I have found it would be close and the position of the wheel weights would most likely need to be moved.

Hopefully someone who is actually running the 14in XTS setup will chime in with some more info. I am seriously considering it over the ATS 13in setup but I have concerns about the calipers on the XTS clearing my wheels.

I would think the 11.65"43mm caliper is a requirement if you chose to run the XTS front setup. I just don't see bias being acceptable with the standard 11.65/38mm rear setup

I've listed mine for sale, but can take any measurements if you want. I have the weights buried somewhere back in the beginning of this thread. IIRC, frontal clearance was the same as the ATS, but don't quote me on that as it's been a year since I've had the setup assembled on the bench. Biggest issue was outer diameter, but from what others have posted, with the offset bushings, they did seem to clear an 18" barreled rim.

BTW, I have decided to purchase that Baer 1 1/8" bore MC for hydroboost.

I agree the 43mm rear caliper setup is a requirement with the XTS 14in setup. I am just wondering what the bias actually is with that setup.

I am on the fence between the ATS and XTS setup right now but leaning toward going ATS. For me I think it comes down to the potential clearance issues with the XTS setup and the fact that I can always step down to 17s with the ATS setup and I wont have issues with the barrel on any other 18s. If the XTS setup had say 1/4in of clearance of my FR500s and other 18s I'd pull the trigger on it. No way am I stepping up to 19s to run the XTS setup as it would completely negate the cost effective benefits of the brakes. At that point I'd just run Stop Tech or Wilwood and call it a day. Maybe @lowranger96 has something he can add on the XTS setup from the feedback of his customers?

The best bang for the buck 14in setup is hands down the XTS setup though. I priced everything out with new rotors, pads and 43mm rear calipers for both setups and the cost difference was something like $140. The cost effectiveness of both setups is amazing if you ask me.

I am glad to hear you're going with the Baer MC. Once I get off the fence I plan on doing the same unless you report back with some negative in regards to running it but I don't see that happening. I honestly can't wait to hear what you have to say about the setup once you get your car back on the road.

I do not have a measurement of the inside of the barrel but the caliper is under 6mm from face of the barrel. Obviously placement of wheel weights is going to be critical. I have not measured overhang yet.

6mm or less is tight. I am pretty locked in on doing the ATS calipers at this point due to the potential clearance issues. This is primarily a street car and I'd prefer not to worry about swapping wheels and running into problems. Thanks for responding.

Anyone whos done the ATS swap, how is the Cadillac font affixed to the calipers? Is it painted over the grey coating? Could it be removed without repainting the entire caliper a different color? Thanks guys and gals.

One person back in this thread I believe said it rubbed off with either brake or carb cleaner.

Thanks man, I read most if not all of this thread I saw one member posted about using something called B17, but I'm unfamiliar with it.
Guess Ill just have to bite the bullet and hope I don't have to do a complete repaint. Not the end of the world if I do, but I'd prefer to avoid it if at all possible.

Np that's what this forum is here for.

I thought it was B12 chemtool he was refering to? That is carb and choke cleaner btw. If that is what he used then I would just grab a cheap can of carb and choke cleaner and give it a shot.

I understand not wanting to paint the calipers. If they were a nice gloss black like you see on other brembos I wouldn't paint them either. I am just not a fan of that gray color.

He used this stuff
https://www.bencosales.com/metal-strippers/b17-procedures-best-practices-the-bomb-of-strippers/


Benco B17 contains Methylene Chloride. It's found in commercial grade paint strippers. I believe the poster used Lab-Grade MCL as Benco sells B17 in a 55 gal drum only. The EPA banned the sale of it to consumers last year I believe. You really don't want to handle this stuff without proper PPE.

Ironically, there's a small bottle of lab-grade MCL on Amazon right now. I would suggest not using it unless you know how to handle chemicals and have access to a chemical hood. That's the only place I would use it.

Anyone try out the ‘11-14 GT rotors yet? I’m actually getting to the point where I can put the brakes back on the car

Any word if these fit with either cosmis xt005r or sve series 3 in 18"?

.do you have the Cosmis wheels? I'm looking into buying some in the next week or 2. How do they fit as far as flush etc? Any pics of on the car?

No, thus why I'm asking. I've had several people say there have been clearance issues don't wanna push my luck if I don't need to.
