11" rotors up front. so your guessing I should use 10" rear drums to keep it more balanced?
That's right, my understanding is with 11" drums and 11" disks you'd have to bias the rear down so much they would lose any gain by being larger. The real test is take it out on a wet road and see if the rears lock up first (and you swap ends). If they do you need to dial the rears down (or upsize the front disks).
