What I have on the car is basically 22mm front and 16mm rear.

The adjustability on the front is via moving the rod end to a different position on the control arm. Moving the location inboard or outboard on the control arm to changes the force applied to bar.

On the rear I currently have no adjustability on the rear bar. On the rear occasion it rains I go soft on the front and disconnect the rear.

I think the fronts are 225 springs but I put them in nearly 25yrs ago and didn't write it down . I have a set of 250s and 200s and the ones on the car were supposed to be soemwhere in between. I prefer softer springs and bigger bars, mainly because I pound over the kerbs in the finest touring car driver style. I also prefer a car biased toward oversteer, especially one with such a low power output.

One modification I still want to do is installing a brake balance bar in the car; along with the oversteer I also liked a car with a good bit of rear brake in it because as you know I rotate the car on the brakes. I think this may also be a byproduct of road racing motorcycles first.

I totally relate to what you're trying to do, fine tuning really does get you the ability to gain lit bits of time on every corner.

PS my repaired counter gear showed up from Bettany today and it really looks to be a nice job.
