Wheel sizes? 13" 6 piston front, 12" 4 piston rear.

I have these new Wilwood brakes going on a custom 69 Charger. will these stop and fill wheel 18" front and 19x12 rear? car prob will weigh 3600.




thanks

They should be fine with 18's in the front but contact Wilwood, if anyone knows, they should...

I think the question is whether the wheels will accommodate the brakes, not visa versa. If you go to Wilwood's website, enter in your brake kit part number, then click on the link to their installation instructions, they provide the necessary brake kit dimensions required to determine wheel fitment. Wilwood makes a few nominally 13" rotor, 6-piston caliper kits, as well as the rears, so that's probably your best course of action IMO.

That's the long and short of it. I know that NASCAR short track setups are getting real close to 13" rotors inside 15" wheels, so it's going to depend highly on the wheel itself and the specifics of the rotor hat, rotor offset and other things.

Sorry about the confusion.

Question is if the 13/12 wilwoods provide enough braking performance to brake the larger wheel/tire on full size car?

And if they wont look undersized in an open wheel.

Thanks

A 13" brake kit will certainly not fill an 18" wheel. And of course a 12" kit will look worse in a 19". But looks are subjective.

Regarding performance. The rotor diameter is one of many considerations. Can you provide part numbers of your kits? But in the most basic sense a properly designed 13 / 12 kit will work just fine on a 3600lb car unless it has excessive power. What do you plan to use the car for?

Now again regarding aesthetics.

13" rotor in a 16" wheel




13" rotor in a 17" wheel


13" rotor in a 18" wheel


13" rotor in a 19" wheel

Thanks JP...Great Pics.

I will be using the Ford Big ends on my Dana. I will need to order the kit for it.
The Fronts are those sold with Magnum Force suspension for the Mustang 2 Spindle they use. The hub is a 270-6989 with a 2.46 register.. I found out they are .68 offset positive.
