The early 911s were indeed a steaming pile of poo - but that was largely due to the ludicrous engine location (behind the rear axle).

Absolutely - no one is saying that you can't have crappy double wishbone setups. But there is no doubt whatsoever that double wishbones are a far more elegant design than McP struts. The latter are chosen purely for cost purposes. The higher unsprung weight you get with McP struts, combined with the awful camber change characteristics makes them a compromise - they can't be anything more than that. While it isn't valid to directly compare track cars with road cars, it's worth bearing in mind that virtually all classes of racing cars (where cost is of much less importance) use double wishbones, not McP struts. This is down to their superior performance and lower weight (and also that they're easier to tune). Defending McP struts on the basis that it's what most road cars use is like saying that three point seat belts are superior to five point harnesses. -- Grunff
