Lotus Elan

How to make your Elan handle

This practice of doubling up on arb's has been is use with race cars going back to the mid 60's in my personal experience, both with sports & saloon cars. So, as an easily reversible experiment, & as I had a spare standard Elan arb laying around, I decided to try it on my own S2 for track use a couple of years ago. Cut the ends off & attached it to the single bar - but using proper & appropriately sized U clamps & bolts (1 by the drop link & 2 as close to the ends as possible on both sides)

I then booked into a track day at Castle Combe (a circuit that I know very well & have lap times to compare with) to check the result, & it was certainly noticeable & effective (this is a road legal car but fitted up with full TTR suspension & used for sprinting, with track day use as well - 175/ 60 Yoko tyres) The lap times were circa 2 seconds faster than I had ever achieved before in perfect conditions - from 1min 28secs.

Body roll was reduced & the car was more stable & faster, especially when quick changes in direction were involved, & through fast corners. I had a mate (who is familiar with the Elan) follow me around & he said that the reduced body roll was very noticeable from behind.

As a result I am leaving the double arb arrangement in place. The only concern I have is the effect on the arb bushes. The standard rubber bushes are ok at the moment, but I have some poly ones in the garage just in case.

For a standard road car I wouldn't bother tbh.
