18" wheels and upgraded brakes thread


Recommended Posts

Many SGT owners have expressed a desire for upgraded brakes and still keep 18" sized wheels. I thought it would be nice to have a single thread where folks can post info about the current 18" choices for larger/better brake systems.

 

07SGT4578 posted that the Shelby CS69 18x9.5 wheels work with BAER 6 PISTON BRAKES http://www.teamshelby.com/forums/index.php...st&p=676122

 

And we know the GT 500 18x9.5 wheels work with the bigger GT500 brakes and the 18" S1 brakes also fit the GT 500 brakes and Shelby's 6 piston brakes (see post#3)

 

What other 18" wheel choices are there out there?

 

Post info and pix.

 

If it becomes a popular thread we can make it a sticky.

I wasn't meaning to keep the stock 18" wheels but rather 18" wheels that work with bigger/better brake systems such as these:

GT500 wheels work with GT 500 Brembo 14" front rotors and 4 piston calipers. Do they work with any 6 piston brakes?

Who's SGT/SC is that with the GT500 rims and AP Racing 6 pistons?

 

AP Racing makes:

- a 13" rotor 4-piston caliper for the Mustang GT

- a 14" rotor 4-piston caliper for the GT500

- a 14.25" rotor 6-piston caliper for the GT500

- an assortment of 13" and 14" 4 and 6-piston calipers for euro spec Fords (including a 13" 6-piston caliper for the euro spec Focus RS)

 

Number of pistons doesn't matter as much as the swept area (contact patch area between the pad and rotor).

That's clark17357' car. "AP Racing brakes (6-pot front, 4-pot rear)" I'm guessing "6-pot" is 6 piston. Here is a picture without the wheel

I too want to keep the stock wheels! I REALLY like them!

 

Me too! Here is a link to the Wilwood kit w/13" rotors... My assumption is that it will fit stock 18" wheels... I'm not good with those silly brake fitment diagrams... Just tell me if it fits or not :censored:

 

Fitment Information:Info / Part Number:Minimum Wheel Diameter (in):18

Front Fitment:OE Hub Offset (in.)N/A

Spindle Type:Disc

 

Wilwood Brake Kit

Cost from Summit Racing is between $1,700 and $2,000 depending on color (black or red) and style of rotor (slotted and/or cross-drilled)...

Thanks Mark.

 

Did he ever mention how far off were the stock rims with these brakes?

I don't recall...may want to pm him.

 

 

The 18" CS56 wheels fit/work with the big brakes. Pictures to follow once the SGT comes back from Tasca.

Interesting. This ad for CS56 wheels says "does not fit the Shelby GT500"

Mark, Thanx for starting this.

 

Just so every one knows. ALL 18" wheels manufactured by The Shelby Wheel Company will work with ANY of the Shelby/Baer kits. (GT-Plus, Pro-Plus, and Extreme.)

I never even measured. The stock rims had little room with the stock brakes. Believe me, I tried to get someone to lie to me that they (the stock rims) would fit over the big brakes but I could not even get that. When I saw the brakes on another Mustang at Stillen, it was obvious there was no way they would fit the stock wheels. If someone would build an 18" stock wheel that would clear the big brakes, I would buy them in a heartbeat. I am old and the stock rims are what we ran back in the 60s so they have special meaning to me.

 

And, Mark, yes, 6 pot means 6 piston. Another old fart way of describing things.

I'm confused now. The S1 was advertized as the only 18" wheel to fit a GT 500

http://www.shelbyperformanceparts.com/Show...S1%20Wheel.aspx

 

But I see your car in 18x9.5 handles the bigger brakes

 

The Shelby PP site says these 18x8.5 wheels can handle the GT 500 (see chart below) http://www.shelbyperformanceparts.com/Show...66%20wheel.aspx

 

But these 18x8.5s don't list the GT 500

http://www.shelbyperformanceparts.com/Show...67%20wheel.aspx

 

Again I confused.

 

What is the ground truth on which specific Shelby wheels will fit GT 500 brakes?

Which wheels are made by the Shelby Wheel Company? Do you mean the American Racing Shelby series (Torq-Thrust, Series 1, Razor, Redline, etc)?

 

You can find all the wheels made by the Carroll Shelby Wheel Company here:

 

www.carrollshelbywheels.com

 

I know it's confusing at times but the Carroll Shelby Wheel Company is the company that Mr. Shelby owns.

 

American Racing does have a line of Shelby wheels that Shelby Licensing licenses them to produce. Shelby is simply a sub-brand in there line up just as their Earnhart Jr line or their Boyd Coddington line.

 

Long story short they are two completely separate entities with different wheel styles.

- a 13" rotor 4-piston caliper for the Mustang GT

- a 14" rotor 4-piston caliper for the GT500

- a 14.25" rotor 6-piston caliper for the GT500

- an assortment of 13" and 14" 4 and 6-piston calipers for euro spec Fords (including a 13" 6-piston caliper for the euro spec Focus RS)

 

I wanted to clarify the AP Racing products available for the S197 Mustang.

 

All of the kits fit all V8 S197s from the Mustang GT to Shelby GT to GT500.

 

There are currently 3 AP Racing brake kits available:

 

14.25" rotor 6 piston caliper front

 

14" rotor 4 piston caliper front

 

13" 4 piston caliper rear

 

 

 

 

Number of pistons doesn't matter as much as the swept area (contact patch area between the pad and rotor).

 

The only reason to increase the number of pistons is to fit a larger pad and gain a larger contact patch. The reason to go to a 6 piston caliper to get a larger pad vs just building a larger 4 piston caliper is to keep the clamping load consistent. A large 4 piston caliper would have to spread the pistons further apart which would result in inconsistent clamping force.
