For the record Troy.....I have never had a problem following Teby or Robert. However flowing Teby's rich running engine is a quite a gas. As far as IRS vs Swing.... I have put several Porsches in the ditch in my days BM. Before marriage, before mortgage, etc. In fact it was part of the learning curve in the early 911/912 cars. My Speedster has a swing axle with camber compensator and anti sway bar. So far my on limits of courage or perhaps wisdom gained with age have kept me on the road.
