Switch to disc in rear

Stupid question but what

Is the e body.. thought I had a body..right??

Yes! just mentioning my E-body Cuda because it has factory braking and weighs a bit more than an A body. The "Listed" cars weight is IIRC, 3650lbs. P/S, P/B, no A/C, small block, 4 spd manual, 8-3/4 rear, S/S springs. Basic MP book build parts back from the early - mid 80's.

I would agree to a point. The power train will have less effort in spinning lighter rotors and rebound in the suspension will be a little harsher with more unsprung weight. However, by moving more weight rearward, the vehicle moves away from being nose heavy and should handle a little better. You are still accelerating the same mass whether it is sprung or unsprung weight so Im not sure it would be faster. The biggest point I would make is that there is not enough difference made in the car's braking for the amount of money spent to convert to disk rather than bigger drums.

No,the drums are not sprung so weight transfer is unaffected. The weight is otherwise dead mass that needs to be rotated or pushed. All of this has been writen about and proven by smart people, not smart *** smarty pants people like me.

Yup! Have to agree here. Excellent example is that your e-body's rear brakes work fine and are completely safe. BTW , were they 10 or 11"?

Stock for '73, 10 drums, small disc up front. It was a bit hairy stopping, but that is mostly a issue of nerves. Plenty of run at the strips end. A lack of vacuum has more play and is the scarry issue if it isn't there! A nervous LOL at tracks end for the new guy!
