Re: [DML] Re: Upgraded Front Suspension

Sorta.  The reason Lotus made the changes was the increase in HP available in 
the drivetrain, the improved braking performance that was added to the Esprit 
and the improvements in tire technologies that improved grip.  Basically the 
cars got faster, could brake harder and could corner quicker which drove up 
demands on the front suspension components.  They went to the lower A arm 
because the bushings could no longer cope with the increased loads on the front 
suspension.  Lotus had to make frame changes along with the LCA changes to deal 
with the loads.  That isn't all that practical for DeLorean owners, nor is is 
necessary unless you start playing around with engine power and brakes.  Most 
owners would be far better served to replace their 30 year old suspension 
bushings than to start redesigning the front suspension.

Doesn't matter what Lotus was doing then -- if they decided later that a lower 
wishbone was better, is it not reasonable for DeLorean owners to do the same?

Lotus Elise suspension (one Helluva spread eagle lower wishbone):

Another view:

Before Marc's brain explodes Re: Elise sway bar: notice how it is shaped versus 
ours -- a very sharp right angle bend versus our approximately 45 degree angle.
