De Deon versus IRS?

Opel GT using a DeDion/transaxle designed for a Volvo or a Porsche?

Nikpro said it best. A "well designed...".

Now, there's nothing wroung with any of the options mentioned as they will be well designed, but they weren't designed for the Opel GT. As well as the significant challenge of making it all fit, things like weight distribution should be considered. I am not sure anyone has ever considered a transaxle on a 7 type vehicle as it could add a lot of weight the rear. The GT has different weight distribution so this may be less of an issue but this for me is a fundamental consideration. If it doesn't "balance" then suspension set up could be compromised just to make it drive adequately. If track work is in the pipeline it may never handle if the weight distribution is fundamentally wrong. Even Porsche took decades to square that circle...

The Westfield FW400 had a Hewland transaxle from the factory, but with the carbon chassis etc it’s so far from being a typical “Seven” I’m not sure it would be much good as a comparison!

Fair point. I had forgotten totally about that. Anyone weighed one on the corner weights? I'd be interested in the front/rear weight distribution both with and without a driver...
