Geo Settings

DDtB · Post by **DDtB** » Thu Oct 18, 2007 6:23 pm

So, what's the general consensus from those in the know for the best Geo settings for an S1 for fast road/track use.

125ish/135ish ride height currently.

iirc it's something like wet 340r settings or 340r road?!?!

Cheers,

Dave.

Yeah so hi jacking Daves thread ...

What is the general consensus for those in the know, looking for fairly agressive S2 Exige track set up geo.

I use 340 road settings and they are ace!!

It aint going to help you though!

Kenny,

Agressive track will kill your tyres and isn't what you want for heading into winter as the increase in camber reduces the contact patch between tyre & road at normal speeds/cornering forces.

When I'm back at work I can dig out something for you that worked well on the S2.

TBH, the book settings for toe are going to be spot on unless you're really good where a reduction in rear toe (i.e. less negative) will ultimately make it a little faster maybe.

If you do plenty of road miles in your car you won't want to run on aggressive camber settings because it'll kill your tyres and will make the car all over the place on rutted roads, motorway white lines, etc.

I would suggest leaving rear camber as standard (I think that's somewhere around -1.8 degrees camber).

I would suggest a tad more front camber than standard (standard is around -0.1 degrees IIRC; aim for around -0.5 degrees).

It's important to get the camber balanced side to side, and it's done with shims. You'll need to buy a bunch of shims from Lotus - I suggest buying only the thinnest ones - get 4 thin front and 4 thin rear. That way you can remove thick shims on each side and put in just one or two wee shims to get you to close to right value - basically you would rather have -0.3 degrees on each side than -0.4 on one and -0.6 on the other - having a stock of thin shims makes it more probable you can get -0.5 on each side.

Chances are your plinth bolts are seized so before you waste the garage's time I suggest you get them removed, cleaned and then refitted with just copper slip. Once the shim adjustment is complete, remove them and refit with Duralec and torque properly. These bolts break and need to be done up with care.

Cheers,
Robin

BTW, that's all for DDtB. For the exige, factory settings rule.

Cheers,
Robin

Factory settings it is

For the S2 exige, i would try to get much more front camber, personally.

Yeah - but it's Kenny's daily hack too and coming into winter with additional camber on 48's could be interesting to say the least!

I was always quite pleased with the setup of my S2 Exige while I had it - I know that the car will be a bit faster with camber set to 11, but overall it will be a nicer car to drive with it set to 7.5 I think

Anyway, Kenny seemed to be going pretty well yesterday (fastest S2 exige out there I think), so the factory settings cannot be all bad

Cheers,
Robin

Dave, did you remember to get the geo set with a couple of hundred Kg of ballast in the car so it's all fine for when your in it driving

That quote is signature worthy

Ta Robin, was having much fun, enjoyed some close lapping with you for a bit (hope I wasnt too close

)

Mac, I have bought a Pug 106 for a runabout over winter so the Exige will only be getting used for fun but I think the factory setting will probably do anyway, maybe a wee bit more front camber if that removes some of the understeer.

Nah, I wasn't worried - it was fun - I was trying to work up a bit more speed to stay with you, but just couldn't get my act together - plenty of speed to be had at Duffus (you were killing me there) - need bigger balls, that's all

Cheers,
Robin
