You seem to be leaning more to a heightened suspension fron stock, but not a full-on competetion setup. All of those parts will give you better handling car and give for a more sporty feel, but not yet a car that is set up for the rigors and tuning needed to be a more track-able car. I would suggest bushings as well, but to br more specific, take a look at:-Front/Rear Lower control arm bushingshttp://
www.pdm-racing.com/prod....html-Tension Control (T/C) rod bushingsLook on eBay for Nismo, or get Whiteline from PDM-SPL Rear subframe collars (they crush the difficult to replace rear subframe bushings, and essentially makes it a hard bushing as opposed to a polyurathane or delrnm repaclement that would be WAY more difficult)
http://www.splparts.com/ Say you are from NICO and you get a discount-Also mabye some sway bars, but really just bushings are necessary. Get those from PDM as well.
Just in case you care to hear others setups/plans:I have Projet SIlvia pillow ball t/c rods, I just ordered a set of Yojohama AVS ES100s 205-55-15, I am ordering Nismo S-Tune coilovers (mabye, still undecided) and ST sway bars. Coupled with CP Racing sways. Yep, that should be decnt for now.
