Hi guys,
Am I correct in assuming that when I convert my 66 Chevelle's front brake to a disc setup that It will have tall spindles? And do these spindles affect geometry? If I do brakes with tall spindles do I also have to do control arms? Upper and lower or just upper? I am considering Master Power Brakes complete street kit with 11 inch rotors. Also considering Global west control arms. Thanks yet again for your help,
Peter

Don't do the tall spindle swap, too many drawbacks for the 1 improvement. I'll post more later on a much better alternative I am working on.

Hi guys,

No, you are not correct in your assumption. This is because the are many different disc brake setups available...

The "stock" Chevelle disc swap (1969-1972 GM A-body cars - Chevelles, Lemans, etc) uses spindles that are similar in height to the stock 66 Chevelles (essentially the same). This swap can use the stock control arms, and all the geometry should be almost the same (not positive if anything really changed during those years)...

The "Tall" spindle is either from the 70's-early 80's Camaro/Firebird/Nova/etc with the 11" brakes, or from 1977-and-later full size GM cars (both 11" and 12" brakes were offered). The tall spindle is taller (hence the name), and so it alters the geometry from the stock Chevelle. It also usually requires the custom upper control arms (shorter than stock) or offset shafts and lots of shims with the stock arms. These tall spindleswork well for altering the camber, but they have an integral steering arm that differs from the stock Chevelle dimensions (and the early Chevelle arm is a separate piece). Some say the steering differences are noticable, while some say they are not noticable in a real world driving scenerio...

If you do switch to "tall spindles". then you do not need to change the lower control arms... You do however need a specially balljoint for the swap. This special BJ is needed becasue the stock Chevelle control arms ball joint hole and the taperred spindle hole both differ between Chevelle and stock "tall" spindle applications. The modified BJ is usually just a stock replacement for the tall applications with the outer body machined to fit the Chevelle lower control arms...


Not 100%, but MP 11" brakes probably use the stock Chevelle spindles, and will be the easiest swap, and while they will have the discs, they will still handle like a stock Chevelle... It all depends how you want to drive...
