Lotus 7 S2/S3 Bushing Source List

[a.moore]

I'm dangerously assuming that since most of the car was sourced from someone else's parts bin so were the suspension bushings.  Is there a list of the original application for each rubber bushing?

I copy info I find on the net, use at your own risk. Some of this may be incorrect.  But I try.  I have not seen a complete list of the donor vehicles.

[EdWills]

@IamScotticus has supplied a very comprehensive list of types and sizes for a Caterham and Lotus Seven.  The original bushes sourced by Lotus were produced by a company called Metalastik (sometimes spelled Metalastic).  As noted on the web it is: "A famous historical British brand of rubber-to-metal bonded components, including flexible bearings and bushings founded in Leicester in 1937 by engineer Mac Goldsmith.  The brand is now owned by Trelleborg, and distributed in the U.K. by Robush"

 

A number of road and racing car manufacturers relied on Metalastik rubber and metal bushings for suspension, engine mounts, gearbox mounts etc.  Lotus as well as many other car manufacturers made use of them as shown on Scott's post.  Caterham still shows a few for sale on their web site, but check to see if they are metric, before ordering for an early Caterham (which may still  have used Imperial sizes), or a Lotus Seven (which definitely did use Imperial).   W
