S2 Suspension settings

Hi All

This is my first post so please be gentle !!!

I have recently purchased a Exige GT (without the GT pack) and need some advice on setup.

I have purchased the Ohlins 36mm dampers & the AP big brake kit & the upgraded anti roll bar in a quest to bring the car back to the GT spec. The Ohlins are the 240R spec.

My question is on setup. I would like advice on the following after the Ohlins are fitted

What is the suggested ride height setting ?
What are the suggested default damper settings.
I would like to set the car up for predominantly track
use.
Does anybody have information regarding advanced damper
settings
Which setting should I set the ARB at after the dampers
are setup

Thanks in advance

Lotus suggest 130mm for ride height but most use 120mm

As for the ARB start with a soft setting second hole from the end and then get it on a track and go from there.

Hi Graham

That’s great - just what I needed.

Thanks for the help

Hi Graham

Just had my Ohlins fitted. Looked at the Lotus Sport settings & have a potentially stupid question

Here goes

On the suspensions settings chart it says for example P7 Bump and P5 rebound.
Are these movements from full hard (turned fully clockwise) or from full soft (fully turned anticlockwise)

Probably really obvious & I await the barrage of abuse

Hi Chris,

I know what you mean, the instructions arn’t that clear. But have dialed in the settings from fully soft on my car. But that’s just the starting point.
My next mod is rear toe link brace and full geo set up, possably at Pheonix Motorsport.

MrD06 · 14 January 2008 10:25

wrong

its from full hard.

also you may as well do the ARB full hard imho.

lotusgray · 14 January 2008 10:59

Have just double checked with a Ohlins distributor and you are right. Settings are to be dialed in from full hard. Will make some adjustments to my car

Thanks David

Not sure about starting off with a fully hard ARB.

MrD06 · 14 January 2008 12:29

you will end up fully hard in the end

Hi MrDO6

Maybe you can help me on this one.

Just did Donnington Park - dry day, little traffic = perfect

Had the ARB set on second hole from the front & the dampers set as per the default Donny settings below. Tyres set at 24 hot allround.

Benchmark Settings - Donington Park
Front Damper
Bump P4
Rebound P5

Rear Damper
Bump P2
Rebound P4

Front Anti Roll Bar P2

Big Problems

Could not get the car to turn in & loads of tyre squeal.

So I softened the front bump by 2 clicks as instructed by the Lotus troubleshooting guide. Result - a little better but still lots of understeer.

Eventually took 2 more clicks of bump from the front & 2 clicks on the rear. Cured the understeer but felt too soft.

I want the car to be sharper & stiffer but if I have to run the car on these settings it sort of defeats the object of having better/adjustable dampers

Any words of wisdom would be much appreciated

Chris

Which model are you driving and what geometry are you running?

MrD06 · 13 February 2008 20:22

what spring rates front and rear ?

Also how much camber on the front ?

do you run a 10mm rake ? 110/120mm ride height

set the bar to full hard as I have said before that helps turn in miles.

and take all your shims out at the front.

chrisexigegt · 13 February 2008 21:18

Hi MrD06

Not sure on spring rates - Std 36mm Ohlins - Says 240r on box
Running 0.5 negative camber on the front. Have bought shim set from Eliseparts ready to make changes (looks like a waste of money eh ?)

Ride height is set at 120mm front & rear.

Thanks

Chris

Hi bruh_la

2007 Exige S GT.

ok change small things at a time

so shims out and ARB to full stiff.
