[928uk] Chassis/shells

[Simon Crowe]

Hi Simon,

I was always impressed by that car. The proportions were prefect, the later Porsche wheels looked like they were always meant to be there.

I never saw any pics under the bonnet or even inside, but externally it was very impressive.

Simon.

Can you bolt a GTS suspension, engine and transmission into an early 928? Did Porsche add any additional structural strength during the various increases in engine output and overall vehicle weight?
