First of all...Thanks for all the reply's. You've all given me some great suggestions and things to try.

Mr Derby...I purposely run the rears loose to put less strain on the drive-train while doing a burnout and to avoid overheating the rear brakes. The rules state no line-locks allowed.

R.Thorne / SSDiv6...Thanks for the links. This is what I was looking for. I will be contacting both companies on Monday and see what they suggest as far as material and shoe sizes.

SStockDart...From what I've read you're correct on standard Roadrunners, but in my case (440 6BBL A12 option) was only available with manual 11" drums or power assist 11" manual drums.

Myron...I think no matter what path I take (as far as material), I will try running the large shoes front and rear.

Larry Hill...There are no self adjusters in the rear and I do re-adjust after every race. They're adjusted so that I can slide the drums on and off with no noticeable drag. I will get a brake pressure gauge and see where I'm at.

Eman...Regarding the line-lock issue - the series that I run in is for restored factory muscle cars. Stock cam, exhaust, factory size tires (G70 15's in my case), etc. The organizers specifically say no line-locks...I don't agree, but that's the rule. I think I will pursue the brake shoe size/material first before changing the wheel cylinders.

Greg R...I'll leave the wheel cylinders/master cylinder option as a last resort.

My reply is a little long winded, but I wanted to address all that took the time to answer.

I realize I may be fighting a loosing battle by running the rears loose, but was hoping to find out if a better shoe material would offer better stopping distances and holding power at the line.

Thanks again for all that replied.
