Alingment Questions Hi,
I just installed a SLP Level 1 kit, and have two questions;
1. do I need to get an alingment
2. if yes, then what specifications do I use
Thanks in advance for the help,

Re: Alingment Questions Yes you do need an alignment. I put one on my '94 3 years ago. As for the specs it all depends what you are doing. I was autox'ing the car at the time an went with 2.5 deg neg camber and 0 toe.

Re: Alingment Questions With 2.5 neg. camber you will eat up tires very fast. I am going to autox in road course and I am going to be runing -1.2 to-1.5 camber toe out 1/16 and as much caster as posible 5 or 6. with this setup you would have to have upper and lower A-arms and tire where is not to bad! Oh, and if I drive on the streets the steering wheel will allways be turned to the right b/c of angle of the road.
Re: Alingment Questions Camber does not cause excessive tire wear problems, excessive toe does. I see no good reason to run toe out. If anything run toe in to counter-act deflection during accel/high speed straights. Toe out will cause excessive drag on the the straights, increase tire wear, and will have a negitive effect on cornering. People believe that toe out should be run because your inside tire leads you into a turn, the problem is that f-bodies like to be trail-braked. Since your on the brakes the inside tire will have little effect on the cars line, instead weight will be transferred to the outside front tire, thus having the greatest influence on the cars line.
Re: Alingment Questions 1. Yes
2. For just a street car, it's been recommended to me to get negative 0.8-1.0* camber, 4.5* caster, and 0 toe. These numbers should be equal side-to-side. If you're a perfectionist, disconnect an endlink to remove preload and sit in the drivers seat while the alignment is performed.
In general:
The goal for camber is to achieve a small amount of dynamic negative camber while cornering, ideally set via tire temps. For highway driving, any amount of camber over -1 degree will cause rapid wear to the inside of the tire. More camber will also cause a slight reduction in straightline stability.
Add'l positive castor increases the self-centering effect, which improves straightline stability and driver feel. Less castor reduces tire scrub while cornering, but reduces stability & feel.
Toe-in improves straightline stability while toe-out will help steer a car into a turn by reducing corner entry understeer slightly. Toe-out causes a car to wander in a straight line, and is not recommended for street driving. You can use tire temps to set this as well.
