Consider these... http://www.ebay.com/itm/FORD-MUSTANG-13-...#ht_1823wt_1324 You'll need big wheels but the bolt pattern is 5x4.5"... You'll need to build adapters to mount the calipers.... But that deal gives you most of you front brakes for cheap... "The Armies of our ancestors were lucky, in that they were not trailed by a second army of pencil pushers."

I have the pattern if you want to use them with drum spindles and hubs. They wont be aluminum but they are new design and dual piston....Tim Quote: Consider these... http://www.ebay.com/itm/FORD-MUSTANG-13-...#ht_1823wt_1324 You'll need big wheels but the bolt pattern is 5x4.5"...

They might be OK for an a-body but I wouldn't want them on anything heavier, they were certainly marginal on my car prior to all of the mods. 94+ Mustang Cobra stuff can usually be had for ~$300, calipers, pads and rotors.

If there was an aluminum caliper that could easily bolt on to a Mopar 11.75 rotor then I would've designed a kit to accept it. There isn't. Which is why I designed the AR000 kit to work with the Wilwood calipers. Wilwood calipers are cheap, not expensive. They really are too cheap in some ways, which is why I went ahead and designed the AR011 Viper on 11.75 kit.

These calipers have been around eight years, they a common & cheap plus there are tons of good pads available for them which makes them very attractive to hotrodders..

I never thought of using them on my Challenger which already has 11.75 rotors. The calipers are pretty light at 4.9 lbs each (without the adapters). The adapters wiegh in at 3.8 lbs. They are metric and designed around a 30mm thick disc so spacers would be needed for the thinner 11.75 disc. The piston diameter is 41.5mm. I don't have a spare 11.75 rotor and spindle to try a mock-up on, but I bet it's alot harder than it looks to adapt these. 2007 Mustang GT Vert 2004 Ram 2500 QC 4X4 1971 Challenger Vert 5.7 Hemi Project

Actually they are 43mm which has an effective area of 2900 sq/cm... But the Viper uses a staggered piston configuration 44/40mm which gives an area of 2775 sq/cm... So it doesn't sound like the Viper calipers are as good a choice as the Mustang caliper... The stock A body 2.6" single piston has an area of 3420 sq/cm However using dual pistons applies a more even loading to the brake pads & in fact the surface area of the pads is greater, plus as I mentioned in an earlier post there is good aftermarket performance support as far as pad material..... Without doing a bunch of research I can't give any kind of accurate numbers but between bigger rotors with their greater leverage, larger more aggressive brake pads which are more evenly loaded.... You wind up with greater braking force that can be modulated more effectively... Last edited by 1_WILD_RT; 08/18/12 03:22 AM.

I just compensate with a 15/16" bore master cylinder. If I'm not mistaken, a 43mm dual piston caliper yields an area of 4.5", which is still 1.43" less than a common 2.75" bore Mopar slider caliper. BTW, you can get semi metallic, ceramic and EBC "yellow" pads for stock Mopar calipers. Contact info

I agree the Mustang calipers have less clamping force than the stock single piston calipers, my point is Andy suggests thats a problem while using the Viper calipers for his conversion which have even less clamping force... And yes there are performance brake pad options for the Mopar caliper but not as many or as cheap as the options available for the Mustang calipers...
