Lotus Replacement Chassis Number

I also suspect that there were far more daily drivers at the time than now.
I'm a fair weather driver now but in the 80s I used it much more as did others I know one of whom had no other car for 10 years and hill climbed his very successfully at weekends - back in the day when they wouldn't run a separate road going class and he just put low profile slicks on for racing.

These chassis certainly appear to have been fragile in the early days. Whether that was due to manufacture of the chassis, environmental effects or simply use, is up for discussion. Most certainly, many chassis have been replaced over the years. Some to the original manufacturer’s spec and some to a totally different aftermarket chassis design from an independent supplier.

Either way, the longevity of many ungalvanised ‘Lotus Replacement’ examples suggest it wasn’t the galvanising process of the chassis that was the key change.

Oh, and if the vehicle manufacturer calls it a chassis, that’s good enough for me!

Same on my 1972 Sprint Subframe (chassis) change 1985 (Lotus Galvanised not painted) still perfect.
