I would strongly suggest you do NOT cut the stock springs. You will blow out your new struts faster and the ride quality will suck! Save up and buy a set of TRD ones from Aaron at Lithia Toyota (email
awillis@lithia.com). He is running a group buy on them and those springs will probably be discontinued soon (if not already). It will be cheaper in the long run to change out the springs now and than having to replace the blown struts from cutting the springs.
