Rear is KYB Buzzspec dampner with 6.5kg spring , the buzzspec isan 8 way adjustable , much stiffer valved AGX made for Japanese gymkhana events .
im asking 650 for this setup . If your intrested this price is somewhat negotiable , none of this 200 bucks cash right nwo garbage the fronts alone are worth about 500 $
BTW for ricers and such this is straight JDM y0 i just got back form japan and brought this with me off my buddies 180sx
