Springs- Elise vs Exige

[jdegrieck]

Can anyone tell me if the spring rates are the same between the base elise, elise sports pack, base exige s, and the exige s track pack? I know there are 3 lotus spring part numbers. I am guessing the elise sports pack and the base exige s share the same springs (which are stiffer than the base elise) and that the exige s track pack has the adjustable perches but the same springs as the elise sports pack and base exige? thanks

I have been compiling spring rates from this site for some time. None of it makes sense yet.

I also suggest springs from the track pack 2008 are different from everything else. I will be finding out more as time goes by due to inquiries I am making.

This might shed some light on the issue... the numbers in the post were taken from the online Lotus Service Manual that I downloaded about a year ago...

Lowering track pack (ride height) even further?

"Converting to lb/in... (Elise: 242/342 lb/in front/rear, Exige 271/371 lb/in front/rear)stock,
Track pack dual rate: (Front: 180/271 lb/in, Rear: 266/371 lb/in)"

Thanks, so it looks like the exige track pack springs are no stiffer than the base exige (i'm not sure what the dual rate means). I assume then that the lotus sports pack springs are the same springs as the base exige springs?

According to the manual, LSS (Lotus Super Sport) is synonymous with the "Track Pack"

Dual rate refers to springs that have a different spring rate when lightly loaded vs. heavily loaded...
