I have had four wheel factory drums on mine for years. Lighter than the factory Disc. When I was going mid-12 years back, they stopped on a dime both on the street and the strip. I had them adjusted to be draggy for street duty.
Loosen 'em up for the night haunts and the strip.
Now I go...... well..... I don't know, but a lot quicker and they still stop good. I keep them up to snuff with new parts and good HD shoes and drums, plus I respect the horses on the street and have a good 1/4 of a mile to stop on the track.
Make your choice, but always get quality pieces for good peace of mind.
