wheel question on 97 cobra

i want to get a set of nitto drag radials for my 97 cobra but don't want to mount them on my stock rims because I just put on new tires and don't want to be running around on drag radials all the time. so I was thinking of just picking up a set of 97 gt rims from a junk yard and just mounting them on that. anyone have any better ideas... like maybe a cheap aftermarket rim good for mounting drag radials on?? and which rim size should I get? thanks

anyone else?? i was looking to spend about 100 bucks on both wheels... so I'm thinking the junk yard is going to be the only way to go I just don't know what year and model rims would be best. and what size tires to put on them.
