More BBS wheel questions

[lowyder993s]

Question: I'm tring to cobble together another set of track wheels out
of
BBS 3-pc. wheels. The current centers I have on the car are marked
"0226023". They are gold. The ones I'm trying to make the same as these
have
centers marked "0226004" on the front and "0226257" on the rear. They
are
silver. My question is what do these "022" numbers represent? If I
order the
exact same wheel halves as the one's on my car now, will there be any
difference in overall width or offset? The reason I ask is that I have
RSR
flares w/ 315's stuffed underneath. I only have about 3/8" slop overall
before the tire sidewall rubs either the fender lip (which I've already
hogged out) and the adjustable spring plate bolts on the inside. I've
scoured Rennlist and pelican parts BBS's and can't find anything on
this.
BTW...the wheels are 17" dia. Thanks a bunch for the help. Jim
