Anti-Sway Bar - S vs. (NA)

Is it worth it to buy/Replace the Evora (NA) anti-roll bar and put on an Evora S anti-roll bar? will it fit?

If I understand the difference between the two sway bar is .5 mm

(Also I need to replace the Rubber Mount, anti roll bar
diameter to 21.5mm)

does anybody know the other suspension part number from the S?

thanks

I believe from 2012 on, they are all S spec. Nominal difference.

As far as sway bars go, the difference is nominal at 10% stiffness change. I believe Lotus was more focused on the rear weight increase in the back of the S/C'd car.

Bars and Dampers remained difference between NA and S/C through life of Series 1, what became the same post MY12 was suspension arms (actually the bushings) became the same for NA's automatics as used on the S/c man and auto.

NA man & auto:
rear ARB 21 mm (black) A132D0039F
ARB bushings A132C6013F

S/C man & auto:
rear ARB 21.5 (grey) A132D0061F
ARB bushings A132C6016F

Out of shear curiosity, why do you believe your suspension needs to be upgraded?

Always amusing to me when someone gets one of these magical cars and starts changing suspension and actually believes they know what they are doing.

In all fairness, even if one of us were the genius of our generation, it would almost certainly require years of research and trials and refinements to better some area of human endeavor.

The sort of thing that Lotus have done.

Not sure what you are looking for but I have tinkered a little with mine. I have a set of tailored Nitrons fitted on my Evora S. It is an improvement over stock in my mind.


Then again Lotus haven't changed the suspension on any of their Evora's since launch have they? S1 NA same as GT430?

As I understand, changes have been made to compensate for some changes in power and weight.

But the bigger changes came about when there was a change in philosophy as the 400 came along. As best I can tell, they wanted to dumb it down a bit aiming for a broader audience.

430 is different that 410 which is different that 400, which is different than S which is different than NA. Common between all is geometry of suspension attachment points.

Getting back to the original question...

It's very unlikely to be worth it to increase the rear bar by 0.5mm. The difference is academic. Tire compound/size/temperature/pressure, road surface, and nut behind the wheel will dominate any small change like that. Lotus Sport makes bigger front and rear bars. I believe the part numbers are: ALS5C0089J (Front), ALS5C0090J (Rear). Some of us contend that even these are too small.

The evora suspension is an interesting compromise between comfort, performance, and *budget*. If you're willing to give up one, you can certainly improve the other. Personally, I'm willing to give up a lot for better transitional response. Therefore I'm a fan of big, big bars. Well that and the fact that the SCCA doesn't let me change springs. :-p

I may have been exhibiting a little English facetiousness.
However Lotus like all other manufacturers make a compromise on all components between price, performance and road ride. You can tinker with whichever aspect you like and gain an improvement that suits you. To attack another enthusiast for asking what's available is a poor show. No need
