Wilwood, Front brakes, 12,19"..

LW_horse · Mar 11, 2007

Wilwood, Front brakes:

Has someone tried to modify the 12,19" rotor kits below to fit a Mustang 65-67 or 70 spindle?

Early ford, 1937-48, #140-8583
Pinto / Bobcat, 1971-80, #140-7017
Mustang II, 1974-78, # 140-7017

Wilwoods own kits for early Mustangs has only 11,75" rotors, which is a "poor" match to their 12,19" rear disc brake kits (with parking brake).

I am pretty sure you can, I can find out for sure tomorrow for you. I have Cobra Automotive's "Big spindle" which I pretty sure is the large bearing 70 spindle. I also Have the wilwood SL6 Big Brake Front hub kit for a 1971-1980 Pinto 1974-1978 Mustang II Part No: 140-7018-B. Ill give CA a call and find out what spindle it is for sure, I can't rember off the top of my head. So I would figure you could do the same just with the different kit.

I have to keep digging, around i know i have better pictures of the whole setup.

Thanks for your reply, 68FBJJZ109.

I really appreciate your assistance, helping me out.

I'm looking forward hearing from you again!

LW,

I'm a little confused by your question. Do you want to modify the Wilwood 12.19"
rear brake kit to fit on the front spindle?
If so, I would think that would be more trouble then it is worth.

If your just looking for a 13" Front brake set up to complement the Wilwood 12.19" rears,
then Global West makes a nice kit that fits '70 large pin spindles -

THESE KITS CONFUSE ME

do they make a kit that is about 13" for the front of a 69? all i see are smaller kits and i dont know what one to pick..

65 fastback · Mar 12, 2007

Mike - Global West makes a 13" kit

or you can buy Wilwood kits from HotRodsUSA - http://hotrodsusa.com/ - that you can customize to your needs.

An important consideration with both the Global West and HotRodsUSA kits is they DO NOT change your wheel offset.

That Wilwood kit from Summit will change your wheel offset - 1/2" outboard.

Hi Tim;

I want to use the #140-7143 rear kit with 12.19" rotors in rear, and a matching front kit with 12.19" rotors.

I do not want to go with bigger rotors, since I'm running both street & strip 15" tires (0 and 6mm offset).

Regards;
/Lars

Lars,

I don't think you are going to get those 12.19" rotors inside a set of 15" wheels.
You are going to need to stick with 11.75" rotors for 15" wheels.

Check out the HotRodsUSA site - http://hotrodsusa.com/ - it is very informative
and has some well put together kits.

Thanks for the link & tip Tim.

Seems like I need to have a thorough look 15" rims fitment with 12,19" front rotors.

However, Summits homepage says min. wheel size is 15"..

I've had a look at Cobra Automotive's homepage, and their "Big spindle" appears to be the 70-73 drum spindle, which is close to my 70 disc spindles.

68FBJJZ109; What kind of modifications did you perform? Modification of the caliper bracket? New bracket? etc

Need your help here.

What size is that rotor and what size is the wheel?
