But others long ago up graded to the 12.9... <SNIP> Who knows if Chapman, Kimberly, or anyone else @ Lotus even bothered to research this. Don't forget that the only time anyone really put any kind of real effort into engineering the DeLorean was when either JZD, or someone from DMC showed up. Other than that, they shoved the prototypes into the back, and were working on Esprits. Not even Chapman wanted to work on the DeLorean project. The Juhan's are the one's who made him take the contract. I would have to go with the theory here that Lotus simply transplanted the specs for the pivot bolts on the trailing arms to the DMC-12 from the Esprit. Granted the pivot bolts on the trailing arms are cause for concern if you have not inspected them. Maintenace is the key to detection of future problems. So worrying about a sudden failure out of the blue probably isn't a concern. But they are a critical component for the rear suspension. And for Chapman & Lotus to be experts in suspension design and engineering, they obviously failed to lived up to their reputation in this case. I'm not knocking Lotus' ability, just their dedication to contracted projects. I'm sure that if you own a Esprit, you probably have no worries. But if you own a car made by another mfg who contracted work to Lotus, be wary of what they designed. -Robert vin 6585 "X"
