5450Stiffer springs for towing
- Nov 25, 2014I have a 1987 U.S. 535is, 5 speed that I want to use to tow my boat with a single axle trailer. I noticed in the Euro parts diagram that there was a trailer hitch available.Does anyone have information for a stiffer rear coil spring (or spacers) to maintain the rear end height. The only discussion I have come across on the subject is atAlso, has anyone used their E28 to tow, or know the rated towing capacity for the vehicle? I was using my 1983 U.S. 733i with an automatic transmission to tow before without a problem but that car will no longer pass the California smog test.Gene M.
