look at www.racingextreme.com for the springs / struts
and here: http://www.axronline.com/store/list_products/?category_id=573781 for AWR rear sway bars.. you could also buy the racing beat ones off somebody with an MP3 or a MSP.. i think that works too. I've got tokico HPs and I'm gettin eibach springs.. I think a good idea would be to take a short ride with roywhite, see how you like the feel. It does get quite a bit stiffer / bumpier with struts alone, but the handling is great.
Have you seen the "ebay" OBX 4-1 headers for $169.99 thread ?? I was looking at it, but naw i dont think its a good idea. I would rather get headers from some other place than ebay, but the price seems very good tho.
If you look under your car and follow the exhaust pipe from the engine to the rear bumper, it's the silver colored can under the passenger compartment. It's smog equipment. We actually have two of them, one just below the exhaust manifold(thing behind the heatshield), and one where I mentioned.
yes, because the bends in the stock pipe are restrictive. Most aftermarket pipes are mandrel bent(no restrictions), and have bigger gauge piping, so they flow better.
