HELP! Front Suspension Woes

[Buick Motorsports]

Hey Guys,

First I will start with the information on the car:

-85 Buick Regal, SBC, T-Tops, 16,000 mile car.
-17x8.5 w/4.47" backspace. 245/45 fronts...275/40 rears.
-Suspension Techniques 1" drop coils
-Napa VST shocks front and rear
-UMI performance tubular rear control arms (poly bushings)
-7/8" front sway bar, no rear sway bar
-seat and front fram braces.
-installed missing body cushions.

Here is my problem, on larger dips in the road the front end seems to float and have an excessive range of travel. This results in the front wheels making contact with the inner fender well just inside the fender lip.

I estimate that the highest point of contact in the well amounts to about 3.5 - 4 inches of total travel. Too much?

I have 1 3/8 front sway bar and a 7/8 rear on order, will this help?

Would a Koni double adjustable shock help the problem? or just create other ones?

Thanks for any input you have.

Jason
