Fork springs - cutting them makes them stiffer, no need for aftermarket springs?

I'm with joerock on this one. Its not really a good idea to shorten the springs without going up on the stiffness, it'll just reduce your useable suspension travel.
I used to do it on my old hot hatches Years ago. Chop a coil off the springs to lower it, it just made the car hit the bump stops earlier, and with one hell of a bang!
I'd go with changing the oil first as most have come up with great results for it. Ill be doing mine at the end of summer as my front eng is getting a bit baggy. :o
