New Öhlins, should I also upgrade Sways?

I just installed Eibach anti-roll bars on my '99. I run Hankook RS-4's at the track and stock dampers and springs. I have about 20 years of racing/tracking/autoX experience. Just the addition of the anti-roll bars made the car handle fantastic. It didn't hurt the ride, it significantly reduced roll, and it turned the car into a precision instrument. I did a back-to-back at our local track and while the car was fantastic before(for a stock car), it was just so much better after. My ability to place the car EXACTLY where I wanted to with no understeer was incredible. I am currently waiting on a set of Koni Special Actives. They are by no means a track damper like an Ohlins but my car is mostly a top down cruiser and my wife loves it so I couldn't go too track focused. Truly I don't care. Having had many dedicated track cars, I've been there and done that. The Boxster handles beautifully out of the box(no pun intended) and rides great. Adding the Anti-roll bars was the icing on the cake. At our local PCA events at Mosport, I routinely out brake and out corner many, much faster cars. The Boxster is a fabulous track weapon made even better with some stiff sway bars.

This was fantastic info, thank you. I'm planning on similar improvement as I do track the car also few times a summer.
Were there some optional Eibach arb specs that you installed or do they carry only one spec for the front end and another to the back end?

Eibach only has one spec BUT the rear is adjustable with 3 different positions. I have only run the centre hole at this point but come springtime I plan on trying each position during the same track day to feel the differences. I prefer a car that is neutral with a bias towards slight oversteer. Based on my initial impressions with the bar at the centre hole, the car was very neutral and easily steered with the throttle. Want to tuck in? back off the gas a hair. Want a touch of oversteer? Gas it hard. But it's so easy to control and place the car. The sway bars made what I already considered magical steering just that much better.
It should also be noted I run 1.5 degrees of negative camber all the way around with 1/32" toe out in the front and 1/32" toe in the rear. I plan to run 2 degrees negative in the front this season based on my tire wear.
I can't wait to try the car with the Koni special active's and slightly stiffer "S" springs. I was struggling at Mosport to get the car to settle at initial turn-in, it just didn't want to take a "set". I'm hoping the new setup will help with that.

Fantastic, thank you Darren. I'll try to follow the same as you have done and test it on the track when the snow disappears.
