Are there any brake systems that fit the above descriptions?

Baer, STop Tech, Brembo, Wilwood...

If not what is the largest available?

 

The 15" Brembo kit for the Expedition will NOT fit the stock wheels

 

Hey Cliff,

Baer has come out with their Extreme Claw system and Stop Tech now have a six piston ST-60 system. I e-mailed both to see if they have the L in their application. Were not big business for them.

Would there be any advantage to put a six piston system on a 14 or 14.5" rotor? I believe the important thing is not necessarily the number of pots but the total pad surface.

In my quick research, I found out that Stoptech make a four piston system with a rotor size of 355mm which is 14.2".

Lets see what else is available out there.

 

AP Racing has an awesome kit with 14 in rotors and 6 piston calipers.
I put this kit on and did 4 120+ to 20 stops in a row and still had plenty of brake left. Really pricey though.
But I would rather have better brakes than make it too fast to stop.

 

TCE 13" 4-Piston kit is all you need with the right pads....

Any pics, how much and who sells it?

 

Well, well, well.... Just got off the phone with Brembo and surprise, surprise the new GT package is listed for the Lightning. That includes a 380mm rotor (yes 15.2") 8 piston system available with your choice of colour for the calipers and the rotors in slotted, drilled or a combination of both. I had them check with their technical and they assured me that it fits on the stock wheels. Apparently the compact design of the calipers allow this to work. So I guess this is the new BIG DOG on the block. Certainly not cheap at $4295 but for a primo system that will put you throught the windshield, its what I've been looking for, considering what I do.

I guess this exercise was worth it after all. Sometimes its worth asking the same question over and over at the risk of getting the guys with the white coats carry you away.

Have you measured the I.D. of the stock wheels? I can't see a 15.2" rotor fitting. What are you doing that you need that large of rotor? I have use both the Brembo 355mm and Stop-Tech 355mm and can't imagine what kind of racing you will do to warrant the 380mm. Seems like added weight and rotating mass to me.

 

I just measured my track stock rims. They are tapered on the inside and start at 17 3/4 and end up at 15 3/4 at the mounting surface. There is no question that the 15.2"rotor will fit. The only issue is the calipers and Brembo say that they do. As far as weight, Brembo use lightweight materials and yes I drive the ****** out of this thing in 30 minute track sessions all day long. So better brakes is very desireable.

Here is a shot of my L with the Stop-Tech 355mm rotor and 18" TSW wheels. Kind of hard to see but I only had 1/8" clearance between the wheel and caliper. This wheel was not tapered on the inside. The brakes would not clear the stock 99-00 wheel style. More photos in my gallery.

 

Isn't 380 mm more like 14.96 inches?

380 / 10 / 2.54 = 14.960629

 

You're right. A quick conversion that I use is about 25mm to one inch but it has a certain margin of error which is magnified when you have 380mm. As you show in your formula it is 25.4mm to one inch.

 

The issue is not what the rotor OD is guys, it's the caliper body radius. Some bodies are lower profile than others in bridge design. And the body standing proud of the rotor surface effects the spoke clearance.

 

Bingo...

 

This is very true, however the rotor diameter does play a part in the caliper location.
