spaz- where are u running at? i am running at Big Boys Toys in Taunton, MA. anyway i am assuming you are running an AE dynamic strut front end, if so, you should be fine, since those things are pretty tough to break, but it cant hurt to have a an extra upper arm and hingepin, as well as the caster shims. for an old style front end just get two extra arms, they are cheap, and they are not symetrical (in that you cannot use the right one on the left side). Also i would suggest maybe some different side springs, otherwise you should be fine, there isnt much that breaks on the chassis itself, normally wear and tear is on the body (espically with the lightweights) and the tires.
