No secret. I ran #600 rear and #450 front, with the shocks set on medium. Rear bar on medium and raised the ride height about 2-1/2" all around. We did get airbourne on many occassions and only bottomed out once or twice. In Targa trim, you will be at least 300-400 lbs heavier than your IT setup depending on how heavy your co-driver is. I'm not sure what settings would be a good setup for your VW, but one thing is for sure, a "stiff" setup with 17" wheels just doesn't work on the tough Targa Stages. Jim Kenzie found that out with his "Works" Mini.
