Stock spring question

[Dark Dragon]

Are the stock springs for a TRD Taco supposed to arch or have negative arch? Smiley, or frowney, sorry I don't know the technical term for it.

Should be arched (smiley) :grin: .

so I guess my next question is, are the TRD spring different from the regular taco's. And does anyone have a good set for sell.
