Is this how you lower the 912 rear?
I have a 67 912 and I want to lower the rear from 26" to 25". I have done a ton of searches and they all point to adjusting the splines on the torsion bars.. Are the 912's different than the 911's in this case? Thanks for the help. I am about to put new tires on and I want to lower the car....

Jim...
You have to do it on the torsion bars....sorry no other easy way....adjustable spring plates give you just a hair that is good for corner balancing |

Jim, Just FYI. In the picture of your spring plate you posted, the hole on the left is for the camber adjustment, and the hole on the right is for toe adjustment.

once you know the weight of the car, and you have the car jacked up (all 4 wheels) and level, measure the droop angle of the spring plate when it is completely free of trailing arm and the bottom 2 bolts of the spring plate bushing cover. Then you have a starting point to know what angle to shoot for as you reindex. If you are ordering stuff, I'd suggest new Neatrix spring plate bushings as a 'while you're in ther' deal. They are cheap and you don't want to have to go back later and replace them as it means a second corner balance and 4 wheel alignment.
You can pick up one of the angle finders at Home Depot for about 10 bucks. Use the calculator in this link to get you the new ride height. http://vintagebus.com/cgi-bin/spring.cgi edit: another good thread; long but good information. Torsion Bar Problem, or maybe something else
