There is a really great write up on how to change out the coilovers at renntech.com http://www.renntech.org/forums/inde...showtopic=11342
DJ's method looks loads easier than the one on renntech. His looks easier to take apart and put back together.

While I have your attention, the coilovers have an option of adding a helper spring, What does the helper spring do? If I add this spring will it solve my wheel hop issues? Or should I just change the spring to a light weight. The 300 lb spring I change to is made by the same company who made the coilovers.

You will probably just need to add the helper springs to make your ride normal. I am sure that is your problem. I have the same setup and my car sticks like glue and never bounces. The change out will be easy, just time consuming. You may want to allow a weekend for it first time around and take your time.

To answer your question-the helper spring does just that- it helps smooth out the ride. It is a much softer, flat spring that smooths things over. On your coilovers you won't even need a spring compressor to change them out but you will need to completely remove the coilover Do you have a compressor? You will need to have an impact wrench. If you try the allen key/box wrench method I can almost guarantee you will strip the allen key. It's very easy with an impact wrench. I don't know a whole lot about the spring rates but I think 300 will be too mushy especially if you track or autoX. Try the helpers 1st. If you are really set on changing the springs you may want to check with the guys on the boxster racing board 1st. I am sure they can give you some great advice about spring rates if no one here replies.
