How does a 26R Chassis..........

PostPost by: mark030358 » Sat Sep 02, 2006 4:52 pm

differ to a standard Elan chassis both in terms of strength and dimensions? Will a 26R chassis fit an S3 or S4 shell? Any pictures anywhere?

Top level - A lot stronger ( a bit heavier to). They differ little from the oem chassis in the dimensions required to fit to your body- attached are some pictures of mine . This is a period ( numberd) lotus chassis with the R mod's

DSC05923.JPG and
12ga plate accross front -

inside top done all the way back ( some frames have the side rail relieved for header clearance with a big-bore 4-2-1 and charging sys. not necessary if you run a 4-1 w/o a charging sys, or stock headers, with charging . reinforced ant-roll bare and moto

Lots of work done to keep the rear planted. gussets are done one size up from the oem gauge. blocks used for the diff-rods to abate wollowing.

- the 26R chassis is strenghtened in some places ( rear uprights etc. ) and , yes, will fit your S3 body as there is only one chassis for the 26/36/45 Elan I believe........

..as there is only one chassis for the 26/36/45 Elan I believe........

For the record, there were two variants of the backbone chassis. S1 & S2 cars had the front turrets angled backwards by 7 degrees, whereas the turrets on S3 and S4 cars were only angled by 3 degrees. Obviously, this influences castor angle, hence steering feel and response.

The difference is not sufficient to cause serious problems with interchangeability of the chassis, though, and a 26R spec can be fitted to fit any Series bodyshell.
