Suspension Suspension "Tuning"
Suspension "Tuning"
The purpose of this post is to share what I have found so far.
My first change was a set of easly adjustable coil overs (actually tires and wheels came first). I lowered it about an inch and tried to keep the 3/8" difference between the front and back that was oem. Afterwards I did a track weekend and played a bit with settings (not ht). Car still pushed a good bit when I made a mistake and a little bit at other times. Overall, it was pretty good on track. Did another weekend at NJ motorsports and really enjoyed it due to the fantastic track surface.
The next thing I installed was a set of adjustable camber plates. Started with a -1.5F and close to that rear. FWIW, the Vorshlags are of the highest quality. I did another track weekend on this setup. Very pleased. Pushed a bit coming out of tight turns, but good overall. As an aside, I did my first sesion with my highway setting on my struts (opps), then changed to track settings and what a difference.
I have since added adjustable rear control arms and changed my camber to -2 F and -1 R. My parking lot "test and tune" shows it is hard to induce any push. Plan to test soon on a track. So far, I see no need for a rear sway bar for track use. Time will tell.

36 f and r cold. So many variables, I don't mess with that too much. I am using the Dunlop Star Specs. Seems to work. Track gets hotter and traction changes some during the day. Makes it more of a learning situation.
I have been quite successful running 33 psi front cold and 39 psi rear. The car seems to naturally rotate with that psi using TTO and TBO.
I also run Dunlop Star Specs. They lose their grip after about 12 minutes on the track after they get too hot. The 33 psi fronts help a little.

I am not looking for any rotation. Neutral is the goal. Interesting what you say that about the tires. My son and I both use them. They seem the same throughout a session. I don't sense any loss of grip that is there at the begining of a session. They are my favorite tire.
Chocalate and vanilla I guess.

Rotation is a natural by-product of neutral balance by moving the weight distribution one way or another causes understeer or oversteer. By rotating, you can remove understeer and reposition the car.
Dunlops Z1 are great tires, but they do lose some traction when hot and also they chunk. They only last 6-7 days on the track.

I understand the concept.
Re: The Tires. I have 6 track days and about 7000 daily driven miles. No chunking yet. My sons have more miles, same # of track days without any chunking. Both sets show plenty of wear from the track days.
