On that set up, one set of shims (2 degrees or so) won't be enough.

Go with a double set to get to 4-5 degrees, or you can make a pair out of some thicker tube stock to get you out to 5-7 degrees.   You may find that 6-7 degrees is your "sweet spot".

Bear in mind that if you run more than a single spacer (shim) you'll need a pair of longer bottom bolts for the beam.

Thanks for the response Gordon. I did purchase a second set with longer bolts but didn't install them as I wanted to try an incremental change.

Storm here on the coast in NC spared us so no cleanup today,I'll have time to install the second set. Steering with the throttle is getting old.

Happy Birthday America and have a good holiday.

Glad you dodged the Arthur bullet.  We've been watching emails from friends in Beaufort, SC and all they got was moderate rain.  

I ran about 3.5-4 degrees in mine for over ten years and it was OK.

The last time I had it aligned, the kid who did it was a Hot VW Aircooled kid who talked me into running thicker shims and he brought it out to 7 degrees.  More stable at 80 mph and above, but now I'm getting too old to venture up there 

You may notice it's a bit harder to turn the steering wheel in a parking lot, but that's all.

A "hot VW air cooled kid" is worth his weight in gold
