aggressive stance
I was going to have air shocks do the job since it's easier and cheaper until I kept reading about mounts breaking and expensive damage so it scared me off. Maybe they had rusty mounts or something and didn't check first, dunno.
One thing I would like to mention, especially with all the very different opinions here on everything from air-shocks to rake, to TBs or leafs, to drag race / daily driver, etc, etc ... "car handling".
If it was not obvious before, it sure should be obvious by now, that car handling is a very very subjective subject. What is good handling for a daily driver is likely not good handling for a G machine; what is good handling for a drag-race (or street/strip) car is likely not good handling for a street only car, and certainly not good handling for a G machine. And what is good handling to someone who's driving experience has not ever included the likes of a modern day pony car, a BMW, or Infinity G35, etc etc, is likely going to be considered pretty poor handling by someone who has.
So, this I will ask you - "how do YOU define good handling?" ... and I sincerely hope that your answer includes serious thought as to safety, both to others on the road with you, and to yourself and your passengers. With this in mind (the later that is) DON'T use air-shocks, unless you never drive over 50 mph, and only do that on a straight road where it's legal. And don't mess around with your suspension until you're sure it's sound and secure.
Here's an article I just found and read - it seems pretty informative, although the thought's of course are not mine, but are the author's.
