Re: [DML] Upgraded Front Suspension



Actually the ball joint end can snap off. Byrne has pictures of such on his website, and it happened to a European owner shortly before the old DMCTalk.com site went down.

OEM arms are also easily bent. They are only made of 16 gauge sheet metal.

And of course they rust every bit as badly as a fender or quarter panel (they are made of the same stuff).

OEM spring perches are not only very thin, but their sides are very low. An owner at FFT'11 reported that he tried new lowering springs 
but they kept popping out.

James Espy told me personally he has seen OEM LCA's that won't grip their first replacement ball joint.

Etc.

As far as cost is concerned: Even with new suspension, total investment in my car is less than $15K (I include tires in my total).
