If anything, your camber should be at around 1.2-1.5 degrees which IIRC is within factory spec, but close to too much camber. If you want to get your car to factory spec after lowering, with the setup you're thinking about, I'd say at least get some camber bolts for the front. No need for plates at 1.5"... however, make sure you get a 4-wheel alignment after installing the new setup, as no doubt your toe will be off on all fours

 

RSRs are a bit too stiff for AGXs. IIRC, KYB doesn't recommend running too stiff a spring rate on them because you'll wear them out prematurely.

 

Artic has a good point (which I overlooked somehow) - Sieji, if you go with RSR ti2000 or Down Springs (both around 160-210 lbs./inch), they will work fine with KYB AGX's.

However, you won't match up the shock and spring properly if you go for the RSR Race Spring, which is significantly stiffer at 279 lbs.\inch up front, 194-251 lbs.\inch in the rear. RS-R Race Springs are better matched with Koni's (which I've ran before in my car).

This is why a common recommendation around here is the Tein S-Tech's (180-210 lbs/inch) on KYB AGX shocks. Together you can't bat this combo in the "bang for the buck" category.

BTW for the benefit of others, all the lbs/inch ratings I listed are within range for both S13 and S14; check respective manufacturer sites for the specific #
