Your front air dam may need some work at some time, but right now you need
to concentrate on the handling. Sort out the air dam after you've driven
the car some. I guess I'd be more concerned with getting rid of that hood
scoop myself.
How long have you been on the list? If you can go back a week or so there
have been some good ongoing comments on center of gravity and pressure that
apply to your problem.
Move the weight up front...fuel, water, batteries etc...without having the
car in front of me its hard to tell you where...along the sides of the
engine, front axle, etc. Make provisions to add lead ballest as required,
maybe as much as 250 lbs.
Now keep in mind that this won't help your traction situation any. Get it
to handle first and use the spoiler for down force and traction as needed.
Are you planning to got to Bonneville this year?
