Ye camber adjustment sucks, basically none. either you go it or you don't. I might not have the time to get the springs swaped before this event on sunday, Working late tomorrow and on most of the day Saturday. Sucks. might just do it after any way. got 2 weeks vacation starting Monday, so a lot of time then. we don't really have a track that we can go to for testing but some spirited driving on private road before and after should be good enough.

Did you ever think about going back to N/A? I would do simple DE build or stock VE, 15" light wheels, mechanical LSD and you will be definately faster.

I have, but i have never did an event with an lsd. so i dont want to jump the gun just yet. doing another motor swap isn't in the budget either. If i do decide on a swap, it would have to be a VE. I also need to work on getting another car for daily use and i would have a lot more time to work on it rather than only weekends and small things that I can do without loosing the ride for a week.

Yeah, got it. You will see. Enjoy the car while its running and you will see later.

Alright, disconnected the front sway bar, and initial feel is a little more body roll but less understeer. for instance, going through a round about at 40-45mph with the bar on, the car will start to push(understeer) and correction method was to slow down(or left foot brake), increasing steering angle did not have much difference.. now same round about around the same speed, more roll but more steering angle corrected it so basically the rear end started to 'rotate' like you all said. so, I am leaving it off for this weekend and see how things go.

Right now, I notice the rear is a bit Higher than the front, maybe 1/2" or more. Should I just leave it or set so the height is the same all around? I remember reading somewhere that a higher rear would transfer the weight to the front more, which would mean more understeer. Correct me if I am wrong?

It's not as simple as that. Read this: Understanding Corner Weights: Grassroots Motorsports Magazine Articles

If you don't have access to expensive scales, I would start the ride heights at some baseline settings and start playing around with them documenting the changes along the way. In other words, trial and error. I would use a measurement on the CO's collar relative to the threads on the CO as a way to start. You could use number of turns on the perch as a unit of measuring changes. It's obviously, not as accurate as just scaling the car, but it will get you started in the right direction.

Great info there, I do not have easy access to scales but will aim to do this for next years events. I hope my camera works. Last event for the year and I would really like something to compare to next year.

Well, did place all too well this time around. I think it was mostly due to my driver errors, late in the day I was then getting into a rhythm. I did connect back up the front sway bar, I guess at higher speed it felt good but once going around those cones it actually pushed more. maybe it was just me, it just felt more easier to drive with it on. As well, maybe my rear isn't "stiff" enough or the toe in really hurts the turn in. Will work on that for next year.

As well as turning down the boost. going put it down to 8, with the lsd I feel it is the right way, before I just made up my time with brut power and slow in corners I guess.
