I was looking into toytecs web site for a lift and came across. Bilstein height adjusable shocks 0-2.5 inches (front). But there is a posting saying NOT RECCOMENDED FOR USE WITH SPACERS OR COILS UNLESS LOWEST (STOCK) SETTING IS USED. I have a 2006 sr5 4wd totally stock. I am thinking this would be a better option than using spacers ,and getting new coils for the rear. Does any one have any insight to this set up? From toytec website and bilstein it is not a full coil over just a replacement shock using your factory spring.
