Herb Adams VSE Suspension -  (831) 659-7660

On 01/30/01 I called Herb Adams VSE Suspension and talked to Matt Adams looking for info on the original spring rate for the front coil in the WS6 400 TA .
For autocross Matt recommended the structure kit "Y" brace from the sub frame to firewall \$300, and aluminum bushings for front sub frame to body connection from Comp Engineering.
Since the Pontiac 400 is based on the 350 with a larger bore it's weight will be closer to the small block or Chevy 350 than a Chevy Big block. Matt thought the Eibach 3852.120 should work (possibly lowering the body more than just 1"), but felt that 550 lbs/in may be to stiff for street use. Matt said VSE prefer big sway bars and stock springs cut  to lower the body 1". I asked if there was some formula that related the height reduction of the spring to the reduction in body, but he said as much as Herb had cut ½ coil it relates to right about 1 inch drop. Matt was not certain of the rate on the spring for the WS6 TA, but assumed that if the MOOG heavy-duty front coil spring was 399 lbs/in that when lowered 1" would work fine.
He is ordering some more 1" rear anti- sway bars from the factory, used to replace the stock ¾" bar in the WS6 TA.

PST COIL & LEAF SPRINGS

Coil Springs \$95 to $145 a pair

Restore proper ride height and drive control to your car with new coil or leaf springs. They are the 'muscle' of the suspension system, and new units from Performance Suspension Technology are the perfect way to return the 'brand new car' stance and performance. Mileage, corrosion ,age and hard driving all contribute to the eventual failure of springs.

Since the early 1960's Dick Guldstrand has been a recognized leader in Corvette and Camaro chassis and suspension design worldwide.

The tech recomended the GT spring for a big block with the Bilstein shocks for ride on the Street and Slalom/ Autocross.  He would not divulge the rate, but said they were stiffer than the MOOG 399 lbs/in but softer than the Slalom big block, which is softer than the Hotchkiss at 620 lbs/in.
