Do any replica companies make the Alpina style-stock 13" alloy wheel in any width greater than 5.5 inches, in 13 or 14" diameter ? I was thinking it would be cool to do a staggered 13" set and fill the rear wheelwells a little better.

I was thinking run a 185/60r13 in front and a 2xx/xxr13 or 14 in the back. My alloys are perfect.

Someone has to cast them...right?

You can always run some spacers to push the rear tires out to the lip a bit more.

True,

I really simply want more rear tire. Where is a good place to get spacers btw?

Ebay or H&R, etc.

I had a 185/70/13 & 205/60/13 setup on stock 13" turbines on my other car, and it handled surprisingly well, but it did exhibit some understeer...I liked the 205/60/13 on all 4-corners a lot better.
