Wheels and tires for the track

[Chuck0379]

I've got a mini tubed 68 Camaro with 335 40-18 tires on an 18x12 with 5.5 bs rim. Looking at getting some drag radials for my weekend trips to the track, but I'd like to order some new rims for the back so i don't have to have my tires swapped each time I go to the track. What would be a good setup? Looking at some weld rts wheels but should I go with 15x11, 17x11 or 18x11. Below is kind of what I was thinking of. Specs of the car are 496bbc, t-56 magnum 6 speed, chassis works g-link.






Thanks.
