I currently have suspension techniques springs (lower the car about an inch) and tokiko shocks(non adjust) on my 240z . I bought bump steer spacers and also have a set of Jim Cook racing springs. The Jim Cook springs will lower the car about 2 inches from what i understand. Am I going to have bottoming out problems with these springs installed with the tokikos and stock struts or is it best fo stick with the susp. techniques springs. There must be a reason most of the aftermarket springs lower the car about 1 to 1.5 inches.? Thanks in advance.
