|liquid01||OK ---All tires have a tread to the wall mark. Some are triangles and some are OOO~s some are three to four hash marks it depends on the maker of the tire.....They are all around the outer edge of the tire. This is the limit of the tire roll. If you CAN reach that limit then add pressure. If YOU never reach that limit---------Ya gotta drive harder. But the chalk/shoe white is the oldest trick in the book to find YOUR tire roll over. Do this a few runs and figure either more or less air...YOU gotta do this WE cannot do this for you cuz we are not there. This is a tried and true method....Also if you can drive your foci----Then believe me when I say at a stock level you can out handel most street cars on the block...Just because of the way these cars were set up to begin with....Take the tires to the max----If they squeel dont let up until they slide...Then turn into ity just a touch....Blah Blah...You gotta drive it if you want to win............|

RE: Rear tire pressures.
Those that I listed have worked well for me.
I bumped up the rears to 38.......once.
The tail end was all over the place!
Soooo, back down to the low 30's for me.
RE: Shoe polish.
Very good way to check your tires, (albeit messy) and the above explanation is just fine.
A little "cleaner" way to check the tire roll, though it's not as visual.
I did find, there's a bunch of "circles" on the sidewalls of the Conti tires.
You can actually check how much the tire is rolling by checking if the circles are wearing or not.
They are right at the edge of the tread, about where you'd like it to roll over to, but not past.
^^^^Hope that one made sense, cause I don't have a pic.^^^^

The shoe polish / talk technique is a way to measure tire roll. You put it on the near the edge, make a run, and see how much of the polish gets rubbed off. It should just take off the outer edge, on the tread-portion of the tire. Too much rubbed off means you are really rolling the tire over; Bad for the tire, and handling. Add more air. If none was rubbed off, you aren't deflecting at all; not bad, but you have some room to let some air out.
Try doing a search on the internet for a better explaination. I suck at explaining it.

It's also going to change with the surface. Some of the courses we run on are fairly slick, and/or rough. This is going to call for a different tire pressure than when we are at the high grip events. Track temp makes a difference too. I'd say to start, use the shoe polish trick on your tires to see what you need to do.
If anyone does not know, you put 3 shoe polish dots on your tires, trying to get the center to be right at the edge of the shoulder. There will be a little arrow pointing towards the tread on the shoulder, and the tip of the arrow is where you should center it.

|liquid01||Tire pressuers are going to change with the style of tire you have on the car...With a standard sportlines andfalkens I was up in the 50`s front--Then into total eibach suspension with hoosiers into the mid40-45`s front. The back I always ran about 5-10 pounds less. As stated before depending on the size of the course.|

Get it aligned, and run what ya got.
Once you get a few events under your belt, and a really good feel for the car,
then you can decide whether you want to "mod" the suspension any further or not.
Biggest thing to start off with is tire pressures.
I ran GS all year, and this is what I found that works for me.
These are "cold temps", before a run.
Short course, like a parking lot, with a lot of tight turns:
Long course, like at an airport with higher speeds:
Just have fun, and don't push it too hard.
If you're getting tire squeeling like mad, and pushing in the turns.....SLOW DOWN!

|Templar||I plan on running STS. I added some eibach sportlines before I got interested in Auto X so now I am saving for the Koni adjustables... I was wondering about camber angles and tire presures... Does anyone adjust their own alignment...?|

What class do you want to be in? I am getting adjustable Konis before next season, and some Azenis, but cannot do much else unless I leave G Stock (which I don't want to do yet). I would suggest a good performance alignment (as much camber as you can get and some toe-out in the rear to get more rotation). If you have, or will have, coil-overs I would suggest the alignment and getting corner-weighted. Then take it out to a wide open space and play with it, and see what settings suit your style the most.
I would personally love to get my rear end looser. I have a hard time getting it to rotate and therefore am struggling with understeer throughout the course. But i am not sure what more to do and stay in G stock...
