Stock Becks usually suffer from too much front spring, not insufficient spring. The front torsion bars are adjustable. Check your front torsion bar/ride height adjustment first. There are discussions on the Spyderclub forum, Shoptalk and probably Speedster Owners forum as well regarding the how to of the adjustment. Access to the adjusters is thru an access hole the trunk in the middle of the horizontal bulkhead, or by way of the fuel tank opening. If the car was a kit it may also suffer from binding trailing arms or the wrong length shocks.
