Re: [DML] Upgraded Front Suspension

["Martin Gutkowski" <martin@xxxxxxxxxxxxxx>]

The standard LCAs do not flex under normal use, they are strong in the planes in which they need to be strong. Someone on the old DMCTalk did FEA on a model and confirmed the "boxing in" achieves very little.

Please don't forget to consider Toby Peterson's re-worked ARB bushes which eliminate the vast majority of problems (mainly brake induced) while maintaining the intended design. It's a fraction of the price of Ed's outriggers too.

Ed Uding's outriggers were designed by one DeLorean Motor Company franchise, and are sold stateside by another DeLorean Motor Company franchise. Can we assume they are a DeLorean Motor Company approved product?

Does anyone know how much more wiggly an OEM LCA is with Ed's outriggers than one of Byrne's arms?
