Re: [DML] Re: Upgraded Front Suspension

[Michael Griese <mike.griese@xxxxxxx>]

Lotus change the lower control arm arrangement in the Esprit in 1985.  At that 
time the Esprit had about 100HP more than the DeLorean and was a lighter car.  
They also changed brakes at that time.  The control arm got the additional mount 
to relieve stress from the ARB under braking.  The bushing materials available 
were not sufficient to maintain suspension geometry under heavy braking - 
basically the front wheels would toe out too much.  The DeLorean can't really 
develop those kinds of loads unless additional power and braking has been added.

I am not familiar with every model Lotus ever built. I do know that what was 
done for the Delorean is what Lotus was doing on their own cars late '70's and 
early '80's. The whole frame and suspension is just a scaled up version of what 
Lotus had for themselves although they were not happy about the rear engine 
design. They used a mid engine set-up where the bulk of the weight of the motor 
and transaxle was ahead of the rear wheels. Some of the biggest problems 
revolved around the weight bias and polar moments caused by all that weight 
hanging off the rear of the car. It is a testament to the expertise at Lotus 
Engineering that they got the car to behave as well as it does. And without any 
active systems like ABS or Traction control, not even a proportioning valve in 
the brake system!
