Actually BG, in this area - which is not to say that you can or can not do it; if you really have no idea it is something that you really should have done professionally because even small adjustements in the suspension/handling area can dramatically effect the cars ability both at high and low speeds as well as cornering ability, braking wet and dry etc etc etc. You really do need the right equipment in terms of measuring the alignments made before and after as well as how these changes dictate the cars dynamic handling in such conditions while keeping in mind how such changes also result in tyre wear.
Its perhaps best to be armed with the knowledge and its affects on the car while then taking that info to the garage of choice to then have it done, monitor the differences both on a rolling road and actual. Nothing beats a real world test.
Only small adjustements were made to my car recently and it handles vastly different than previously. It feels far more nimble at speeds with lighter a lighter feel at the wheel making it less controlable at speeds as well as far less confident with the feedback I get from the car because it seems jittery and even minor wheel movements result in instability. It was fear factor 8 out of 10 when I drove it in the rain on the ETC highway let me tell you...wow, it was just so unstable. There is more to the show, but thats another thread lol.
