Narrowed rearend/tires and wheels

[Fras]

Hi,
So Im at the point Im getting tires/wheels and a new rear end. My 68 is not mini tubbed and Ive decided to go with a Moser 9", but was wondering:



1) Is there any performance benefit with a narrowed rearend?
2) Is there any wheel made (meaning not a custom order) that will have the correct offset to make up for the 2" cut off each side?

Thanks in advance! I bought this car about a month ago thinking I wasnt going to change on it....yeah...its like crack, a month later theres nothing on it I want to keep the same!
