1973 Modified 911T Alignment Problem


Vehicle Information: Model: 911T; Year: 1973; Body Type: Coupe; Engine (type, size, modifications): 2.7L; Total Mileage: 99K;

I may have an alignment problem. The alignment shop is unable to get my1973 car to reach the factory specs. on the right rear side. The factoryspecs. below are for 1970 to 1989 cars outside of the US, Canada or Japan(i.e. Euro models). The shop had the USA specs. available also, butdidn't use them. I think because they are either the same or are lesssporty.The RR toe-in would only move to -0.23 degrees (the factory spec. is 0 to+0.33 deg).The RR camber would only move to -0.4 deg (the factory spec. is -1.2 to-0.8 deg).I'm wondering if this is enough of a difference to do something about. Isuspect one of the "new" lightweight alloy trailing arms I installed(from a 1977 that had been wrecked) was bent a bit. If so, the curewould be to find another one on the right side and swap it for the one onthere now. I never had the car aligned before putting the alloy arms on,so it's also possible that it had the same problem previously, when ithad the stock steel trailing arms on it.The front camber spec is approx. 0 deg (-0.2 to +0.2) and my car is setto -0.4 deg.Or, the front could be set to compensate for the rears in some way,perhaps. Yet another possibility would be to take off the spring plate inthe rear and see if I can alter the slot for the camber adjustment sothere would be a wider ranger of adjustment available.
