Standard suspension alignment
Since I couldn't find anything with the search engine I decided to make a thread which point blank gives some basic alignment information for the newb.
The standard front alignment settings are as follows:
Camber = -1* or -2* +/- .30*
Toe = 0* +/- 2mm
Caster and Kingpin are not adjustable (preset at the factory); they are set at:
Caster = 3.55* +/- .30*
Kingpin inclination = 13.45* +/- 1.30*
The standard rear alignment settings are:
Camber = -1* +/- .30*
Toe in = 3* +/- 2mm
---------------------------------------------------------------------------------------
Now for a newb question:
Why is the toe in 3* in the rear and the toe nuetral in the front? If I am not mistaken the front wheel when navigating a corner will toe out a little bit naturally thereby causing a bit of understeer? So toe in would be used to help eliminate that. If I remember that correctly, giving the car toe in on the rear would aid in eliminating the rear tires from pushing out in the turn in as well, subsequently minimizing oversteer?
This would probably explain the stock car's tendency to understeer in general when cornering, in addition to other settings like the sway bars, tire pressures, and so forth.
Does that sound about right or do I have it completely backwards?

factory service manual). So that equates to 0 deg. +/- 0.08 deg. for front, 0.12 deg. +/- 0.08 deg. for rear.
No toe for the front, a bit of toe out in the rear. This decreases understeer.
A good start for a noob would be to set alignment as close as possible to center of factory spec. and then play with front and rear tire pressure to adjust understeer. Tuning tire pressures is free.
Everything else costs $'s. If you go this route, lots of vendors have staged packages to improve handling without spending a lot at one time.Lot of good info in this forum too.

FYI, after I decided on a budget of $1000 and read above links, I'm going with Swift springs and F. & R. swaybars, Whiteline bump steer correction kit, trailing arm bushings, ball joint extenders kit and steering precision kit. Pro'lly go over my budget... as usual.
