First, I must point out that I drove the Spitfire to work today top- down. 'Twas a cold ride home but oh so satisfying! I'd forgotten just how rev'y the engine was, and how much farther apart 2nd and 3rd gears are compared to the GT6. I got sorta' used to the extra torque. And you know, when

One more thing no one has pointed out - don't discount the dynamic aspects of the rear suspension. Proper toe angles will cause the rear to "pick up" considerably when driving, and turning into a parking space will cause the rear to sit at all sorts of weird angles. Backing up really drops the

Nope, ALL springs for the Spitfires (and GT6) are the same distance eye to eye - the longer axles require different radius rod mounting at the body (now that they have different angles for the radius rod mounting), they are now in a different position (angle) since that they have moved outward - th

Doc, Your misunderstanding is in assuming that the angle of the wheel is related to the angle of the suspension upright, that connects between the hub and the spring eye. The suspension upright will change angle depending on the spring length. However, this has no (well, a negligibly small) effec
