N20Cobra

Hey all whats up, I am wanting to go with a set of Weld Draglite's for my 97 Cobra this spring. I want to do a 15x3.5 in the front and a 15x10 in the back. First of all I know I need a spacer for the front, what spacer do I need and where can I find it. Secondly what would be the best tire to run on the front rim I still will be driving this car plenty on the street. On the rears I am going to run an MT Drag Radial or MT ET Streets, what is the biggest tire that I can fit on that rim out back w/out any modifications....I am ok with taking the quad shocks off. Thanks, Jeff
