Cars Handling / Geometry
Can anyone help, am trying to decide what would be the best baseline starter settings for my MEV Sonic7 prior to booking a track day.
Therefore I would be most grateful if anyone could advise on what the basic settings are for the most like vehicles ie Aerial Atom, Lotus Elise (light weight mid engined cars).
In particular I'm after the front and rear camber and toe but would be interested in the front caster angle also.
Many Thanks
Nigel

Hi Nigel,
My mojo will be similar in terms of weight distribution etc, and there is a section of my website on this very subject:
http://www.mymojo.co.uk/mods/mods_sus_align.htm
I found the following Elise data when I was looking for a baseline setup a few years back:
Standard Elise:
F:
0.03 deg toe out (total)
-0.1deg camber
R:
0.18 deg toe in per side
-1.8 deg camber
VHPD Elise:
F:
0.075 deg toe out (total)
-1.8 deg camber
R:
0.375 deg toe in per side
-2.7 deg camber
I found front toe out to not work very well, made the car very darty, so I run with a little toe in as per the website article.
Hope that lot helps!

Unfortunately, looking at settings from another car won't really help you at all. Even settings between the same model of car can vary greatly due to modifications and options, like anti-roll bars.
If you are happy that the springs are suitable for the car then set yourself up a decent ride height that suits the car, and if your doing track work, go for 1.0-1.5 deg negative camber at the front, and 0.5-1.0 deg negative at the rear. The more roll the car suffers from, the more camber you are likely to need.
Toe is really down to preference. Some people prefer high-speed stability, some people like a responsive turn-in, so that's really down to you.
Then just go out and get an idea what the car is doing. You should be able to work out what you do and don't like about the handling after one or two track days, then you spend the rest of your ownership days changing things
