Scottish Elises

Hello,

Generally, our wee plastic cars have far less body roll than the average car . . one of the reasons they're so damn good at cornering. However, I've noticed a bit of roll in a couple of pics from trackdays of my car and wondered if there's anything I can do to cut this down?

For example, here's a pic from Teesside where you can see a fair amount of roll, judging by the gap between the tyres and the wheel arches:



However, in this pic, you can see it rolling the other way as it looks pretty planted on the pax side but lifting a bit on the drivers side:



I appreciate the car can't be completely flat, but I'm surprised at how much it looks like it's lifting, especially in that first pic. I've just got the standard 111R suspension, but I thought the ARB fitted as standard on a 111R would help to counter this?

Anything I can do? Is it actually not that bad and I'm getting concerned over nothing?

I've probably got a long way to go in driver skill before adjustments like this will make a big difference on track, but just wondered if there's anything I can do other than a suspension upgrade?

Thanks in advance for the help.

Get to the stage where it's hindering laptimes first.

You could fit the motorsport Anti Roll Bar, at the expense of a little comfort. I'd invest the money with Walshy to the point that you notice it whilst driving and not just on a camera lens.

The body roll is part of the suspension design. As the chassis rolls it changes the camber angles inside and out such that the available grip on the outside wheel increases. The body roll also adjusts the front and rear toe angles so that the outside rear steers out and the inside rear steers in (i.e. you get a bit of rear wheel steering helping the back of the car steer around the corner). There is a similar effect at the front (known as changing the Ackerman's angle) to help the front end turn.

Firming up the suspension is good for track use, but you need to do something about the geometry too to compensate.

Until you find that you are losing traction at the front I would leave it alone (on S2).

Cheers,

I only stuck the motorsport one on when to combat the understeer I was getting whilst on track.

Cheers guys. I'll wait til I'm at the point where it's genuinely making a difference to track times (once I become good enough to notice!).

Thanks!
