you can use your stock ones since they dont have much of a drop, ask sultan for more info, he has these!!
yeah - I have them and the difference from stock springs is noticeable in terms of stiffness and ride comfort, however the topic of struts can best be answered by the mileage of your celi... If you have less than 50K, keep the stock struts - if it's considerably more then go with aftermarket ones (TRD
, etc) Of course, if you have the cash then by all means just get new struts and springs together. If you look hard enough, you'll find a few places that sell the TRD
strut/spring package for a very reasonable price.
... personally, I only have 15K so I'll replace my stocks at my convenience - probably when I finally put on the 18's
