Look man I am not trying to give you a hard time or anything, but it seems that you lack the understanding behind my words. It is okay if you do not have the capacity to fully understand one's personal situation, although this thread was started for the purpose of learning. Who are you to post inside of the thread with a completely off topic comment? It is not cool to put down another person who makes a decision based on their personal situation or taste. There is such a variety of cars because most people have different developemental and analytical processes. Please understand that I am only trying to help you see reality from another perspective.
The Xa is a fantastic little econ- box for someone who cannot afford to drive a sports car. I personaly have driven an Xa with a very decently set up suspension and think it to be a lot of fun. I would like to congratualate the man who opened this thread on the ownership of such a cool car.
Like I said before I really like the Kenstyle lip kit available for this car, but you can find a lot just by going into some scion enthusiast web sites. Personally I would buy some coilovers or nice springs and shocks first. I think that by just lowering the car a couple of inches you will be quite satisfied. If the lowered body doesn't enrich your retna atleast you have eliminated a lot of body roll.
