If you're not building a racecar, I wouldn't bother with it. The exception would be if there is sag when parked. That would indicate that struts need replaced.

If you are building a racecar, get taller stiffer struts and springs in the back and shorter struts up front. This will help keep the momentum forward when launching. There's a cable mod you can do at the track that has some proven results as well, but you don't want to daily drive with it for safety reasons.
