Excel road spring diameter

Recommended Posts

Have now got spring rates & lengths sorted out and am just about to have a pair of uprated front springs made.

However I could do with confirmation of the diameter if anyone has a spring off the car at the moment.  My guess based on the impressions in an old rubber insulator are:
I.D : 86mm
O.D. : 110mm
Wire dia: 12mm

Can anyone confirm this.

How about lower wishbones, anyone got one off a car they could measure the internal diameter of the spring seat for me?

A couple of places have both told me the ID of the springs is 3.22".  The top rubber spring insulator would just fit into this but it would be tight.  Just need to somehow confirm this would actually fit on the lower wishbone.

Due to modern materials it will be possible to make these out of thinner wire than original (10mm as opposed to 12.5mm) hence lowering the sprung weight slightly.  Therefore the internal diameter needs to be correct whereas the outside diameter will be less than original.
