how to eliminate understeer in the STI (negative camber on the front??)
After having a look at V8venoms STI track videos I know there are some folks out there that really know how to eliminate STI understeer for track use.
V8venom has made some references (on another froum) to the crappy stock alignment setup of the STI as the cause of the understeer. But he has'nt responded to my PM (understandable since he is racing and does'nt want to give away his secrets to his competitors)
I know alot of people put a heavier sway bar in the rear and this seems to reduce understeer tendancy. But from all I've learned from racing is that, doing this will reduce the cornering speed of the vehicle(how many g's it will pull on the skidpad). Thus I'm looking for some alternative solutions.
adding an air dam is an option but It will only truly help in high speed cornering.
I think that adding in some negative camber (via camber plates) in the front end is the best option for the track (it will cause abnormal tire wear on the street)
Is there anyone out there that has a good setup for thier sti for track use?
or anyone who can confirm or deny my suspicions? or give me thier alignment setup?

To eliminate understeer, here's a few things you can do.
*bigger, stickier tires. More grip=less understeer
*more camber (to a point, street tires won't make use of more than -2.5 degrees or so)
*more caster (from an ALK or PSRS- improves the amount of dynamic camber as you turn in)
*more roll resistance to reduce camber loss from suspension compression
