JIC would be a nice choice coz it's well build, but it's far too stiff for normal road condition (not if you driff a lot~ :P) or you can try go to this factory in penang- TKA Absorber. and mod your original suspention to make it 30~200% stiffer (might need 1~2 weeks if you were not from north malaysia.
It'll cost you around 90~200 for one absorber depend on what type of mod you wan to make. p/s it used back your ori spring we just mod your absorber's bounce-re-bounce duty.
one last dvice~ if you wan to get TRD dun buy TRD(tokiko), get TRD(Kayaba)
