I know some people have to want to know how to make their turbo handle better, especially at the track. And how tire pressures,suspension adjustments and the like affect it. Found some good info on wikpedia about handling, thought I would post it here.


[edit] Aftermarket modifications and adjustments to affect handling

Main article: Racing setup
Lowering the center of gravity will always help the handling (as well as reduce the chance of roll-over). This can be done to some extent by using plastic windows (or none) and light roof, hood (bonnet) and boot (trunk) lid materials, by reducing the ground clearance, etc. Increasing the track with "reversed" wheels will have a similar effect, but remember that the wider the car the less spare room it has on the road and the farther you may have to swerve to miss an obstacle. Stiffer springs and/or shocks, both front and rear, will generally improve handling, at the expense of comfort on small bumps. Performance suspension kits are available. Light alloy (mostly aluminum or magnesium) wheels improve handling as well as ride comfort.
Moment of inertia can be reduced by using lighter bumpers and wings (fenders), or none at all.

1) tire contact area can be increased by using wider tires, or tires with fewer grooves in the tread pattern. Of course fewer grooves has the opposite effect in wet weather or other poor road conditions. 2) These also improve road holding, under most conditions.


[edit] Cars with unusual handling problems

Certain vehicles can be involved in a disproportionate share of single-vehicle accidents - their handling characteristics may play a role:

• early Porsche 911s — suffered from treacherous lift off oversteer (where the car unpredictably leaves the road tail first); also the inside front wheel leaves the road during hard cornering on dry pavement, causing increasing understeer. The roll bar stiffness at the front is set to compensate for the rear-heaviness and gives neutral handling in ordinary driving. This compensation starts to give out when the wheel lifts. A skilled driver can use the 911's other features to his/her advantage, making the 911 an extremely capable sports car in expert hands. Later 911s have had increasingly sophisticated rear suspensions and larger rear tires, eliminating these problems

 

good summary, thanks!!

I never knew ligher wheels will improve ride comfort!! Techarts are mad heavy =(
