I am not familiar with any year before the 2007 with the z, but I have a few questions. I see a lot of people are saying for the first modifications to be suspension. After my previous cars, this suspension feels so much tighter and stiffer (even after I spent about $2k on my mazda3 suspension). I was wondering if the earlier years of the z come with things like the front and rear strut tower bars? I want to start modifying and want to know what to do first! Any input is appreciated! Thanks in advance.
