Hi all,
In the process of converting the rear brakes on my fury from drums to disc. Got myself a couple of wilwood powerlites (with handbrake), and now I need
to get some discs.
What size of disks are best to use when using 13' rims ?
Cheers
Tris
The wilwood sierra rear kit uses a 240 x 10mm mk3 escort disc for 13" wheels.

as above, but you will need to modify the hub.
Great, thanks both for the info 
Make sure you dont "OverBrake" the rear, I failed my SVA twice on this, by having std sierra 240mm discs on the front (off a rear drum
braked sierra) It failed on the back to front ballance.
I eventually got it to SVA, with the ballance bar almost full over.(rule of thumb is fronts lock up before the rears)
Later on I fitted the 260mm fronts of a 4x4 Sierra. All nice and even now.
Just make sure its ballanced properly or you could have problems.
Braking is a "Mission Critical" component on the car, Make sure you get it right.

Decent sized drums actually have some advantages over discs on the rear.
