The Prussian Heel Click of the Spitfire

To all Spitfire MK1 MK3 owners

Every owner gets fed up with the problem of the Spitfire rear axle! How many have been caught taking a fast bend releasing the accelerator pedal and ending up in the ditch. There is a reason. You don't need to be a military enthusiast to recognise the Prussian Heel Click
The problem can be briefly described as follows:

The lack of length compensation to the axle produces an extremely positive camber when cornering. With a change of direction in fast cornering, it may even be an over-reaction of the whole vehicle.

The solution came from the factory with the Spitfire MK4 and from SC Parts for the MK1 - MK3. With the "floating" leaf spring in our conversion kit, the camber does not experience as extreme a change when it comes to a fast bend, thus the strong oversteer is prevented. As well as the safety aspect while driving but also for the pleasure of being able to take fast corners we would recommend early Spitfire drivers to convert to the later "Swing Spring" axle. We also recommend the Front Stabiliser to compensate - also available from us.

Best regards
