<VV> Wheel backset

[Paula Tilsley]

Greetings all
 
I've purchased "new" wheels for my LM.  They are 15 x 6 (Chevy Rally)
and I can get the diameter pretty close to original with lower profile
tires but these wheels have a 3.5" backset rather than the original
wheels which have a 4.25" backset.  Combined with the fact the new
wheels are .5" wide than the stock 13 x 5.5, I'm looking at 1.25" x 2 =
2.5" wider stance.  It looks like the wheels will fit in the wells (I
haven't bought the tires yet) but will the wider stance cause handling
problems.  (I was also considering switching to a fast steering box)?
Any thoughts?
 
Thanks,
