Another wheel size/fit question....

I'm finally going to ditch my rally wheels and go for the VWW V45's (after reading just about every post on the topic and seeing tons of pics). My current stock rally's are 15x7 with what I measure to be about 4.5" backspacing (if I did that right). Current tire size is 215/65 R15 all around and my ride height is stock. I have factory disc brakes in front and drums in the rear. I wanted to ask a few questions and get opinions from you all.

1. If I'm happy with the current size of my wheels, am I missing out on any performance benefit of changing to a different size (currently have a 700R4 with 3:55's)?

2. If I want to swap to rear disc in the future is there a minimum backspace I need to get now so they will fit?

3. Should I be considering different size wheels for the front and rear?

4. Is there anything else I need to consider here?

5. Opinion? Will it look stupid seeing drum brakes through the wheel spokes in the rear?

It's a lot of money to spend, I really want to be sure I get it right. Any and all comments or and insight appreciated.

Wondering if my wheels aren't stock now? Was looking on CRG and I don't see a 15x7 stock wheel in 68. I also don't see any markings next to the valve, which the Rally's should have. There is a 10 M marked on the inside of the wheel.

Here are pics of the markings:

Re: Another wheel size/fit question....

On my 68 vert I run TT-D's in 15x7 3.76BS front and rear with Wilwood disc brakes all the way around. Clearance is tight between rear calipers and inside of rim but it's okay. I'm running Hotchkis front and rear suspension plus 1" blocks in the rear. Front tires are 225/60 and rear are 245/60. Next time I'll go to 255 in rear just to help fill the wheel well more.

Looks really great Russ. Thanks for the reply! I will take it that 3.75 should be the minimum BS I work with then.
