2nd gen wheel help?

[Streetking]

Ok guys, been a while and I have forgotten sizing. I'm picking up another couple of early Trans Ams and need to know what is the largest size 18" wheel I can go with on a stock body 2nd gen? I'm thinking 18x8f 18x9.5 or 18x10 rear. I need to know back spacing..

thanks,

From your red T/A when you had the CL205s/TTIIs on it = 18x8 front with 4.5" bs w/255/40/18 & 18x10 rear with 5.5" bs w/295/35/18 rear. I went with an extra .25" bs on my car and ran 255/45/18s front and 295/40/18s rear... Falken makes them. HTH my friend!

V/R,
