PSS9 setup questions

[Topless]

This is tricky because there are many interdependent variables and it is easy to get wrong.
For a mild setting that works:
Use the stock springs and set the shocks to their mid setting.
Set front ride height 1" lower than stock.
Set rear ride height 1/2" lower than stock and have a performance alignment done.

This will improve corner balance, allow more front neg. camber and improve front grip without getting extreme and screwing everything up. For a more precise setup, find a highly experienced chasis guy and gladly pay him to work his voodoo.

The added ballast is doing a few things:

1. Lowering the car
2. Adding camber
3. Changing the center of gravity
4. Possibly altering corner weights

I experienced a similar issue with my coilovers. My first track day, the car was plowing like crazy. When it was totally full of gas, it got very neutral. I added a bit of camber up front and all was well.

That having been said, i prefer slightly lower ride heights than topless. I'm probably 2" lower than stock up front and 1.5" lower in back. I like zero toe front and just a TOUCH of toe in at the back (pretty much zero). If you drive mostly on he street, go with topless' ride heights.

Try -.8 deg camber front and -1.4 deg in back. Consider getting it corner balanced.

In order for Boxsterund914 to effectively corner balance his vehicle, he will have to install adjustable drop links. Correct ?

Yup. Front and rear. Possible to get a decent street setup with measuring tape.

I had always assumed that you get the corner balance by fine tuning the height at each corner (@ the spring perches), not really by pre-loading the sway bars..

However, please note that I am a shade tree mechanic and far from any from professional procedures

you are correct, HOWEVER: when you adjuste the corners, you have added pre-load to the sway bars. the adjustable drop links are used to REMOVE the pre-load condition that's caused by corner balancing.

Ok now it's clear, therefore I should save some and get the adjustable links to compliment the KW-V3's, thank you..!
