narrowed beam ?

[ericglooker]

Im planning to run 16x7's ET:33 with 55 series tires on my '72 standard bug with stock fenders. I plan to have a narrowed beam with dropped spinadls, but Im not sure if I will need a 2in or 3 in narrowed beam (I would like the edge of the wheel to be inside of the lip of the fender). I would try to measure things out for my self but I am at college and away from my car.

I I was also wondering if any one has an idea of what my turning radius will be like with set up?

I know that this has been asked many times but nothing with this specific ET, so any info would be great.

thanks,
Eric
