M-II, Dropped Spindles and Backspacing?
OK guys, did a search and didn't come up with anything about what is the maximum backspacing that will works with the M-II front suspension.
I researched this over on the M-II forum too. The consensus there was 4" backspacing was about the maximum - but this was to fit under the OEM body shell and suspension. FWIW, the factory wheel was 5.5" wide with 10mm offset - which works out to 3.65" backspacing.
I'm interested in a tubular A-Arm set-up using the 2" dropped spindles. My wheels are 16" and have 4.5" BS. Rough measurements look pretty tight on the lower A-Arm ball joint mount, I'm concerned about hitting the inside of the wheel on the arm while turning - or limiting the turning radius so much as to make the car basically un-drivable. Using the standar height spindle alleviates this problem but then places the lower inner A-arm pivot point at a tough location to work around.
Any ideas what the max BS is on this set-up?
