FC AutoX tire pressures/Koni Shock settings
Hi guys, went autocrossing about 2 weekends ago in my 86 GXL with Konis and Dunlop Sport A2 tires.. quite fun! I was really pleased with how the car turned.
I ended up with 44 psi in the front and 41 in the rear (front pressure mainly determined by trying to reduce roll-over on the tire shoulder). Koni's were set about 2/3 stiff all around.
Any experience/advice on those settings? It was my first time autocrossing in a long time, and my first time with the FC since I got a good clutch in it.. ..so although I had no complaints about the handling this time, my senses are not fully calibrated to the car and its potential yet.
I'm thinking of mounting some Azenis for auto-x to extend the life of the Dunlops for the street ($), so tire pressure experience/advice with the Azenis would be great too!
Thanks!
...also, Annand, if you're reading this, hope to see you and your FC again at some future events!

Tire pressures are pretty good range for the type you have. If you go to Falken Azenis Sports, in the 205-50-15, you can get away with lower pressures because the sidewalls are stiff. They are sensitive to temp though. Lower temp requires higher pressure to get them to stick.
Last couple years I autocrossed with the RB bar in front and the stock bar in the rear and stock springs. I set the rear ones full hard and the front full soft. It gave me a nice neutral car that I could get to rotate at will.
This year I put in the RB rear bar and Eibach Pro-Kit springs. I found that the number 3 (of 5) setting in the back was adequate, the rear bar made up for the softer setting, and it isn't so jarring.
This is what works for me. Asphalt handles differently than concrete, so you'll need to develop a series of settings for each. Keep a notebook. Important factors are surface, and ambient temp because they will affect handling for each setting.
