lower too far = bump steer
 

i've read that lowering helps bump steer. does 2" go too far and give adverse affect?

i'm thinking cobb when i go to lower my car, and they advratise 2"(in the front).

I don't think it has a significant impact on bumb steer. Check out this thread for reccomended ride heights from DMS.

Go much lower than this, and you get bad camber juju...

I know my last wrx sat well below the recomended ride height. Those JIC coilovers I had did an awesome job, and i had no adverse effect even though the car was like 3 inches off the ground. The camber was cranked in pretty good too if i remember right.

You must have had different JIC than I did. I think I had the "pogo-stick" edition struts.

The problem is not with static camber, but dynamic camber under cornering load. The geometry of the front suspension causes significant positive camber under load.

You can go lower at the penalty of bad camber in the corners.

my jic's had crazy spring rates on em, they didnt pogo at all. I get what you are saying though with the camber in the corners under load.

I agree..all cars have some level of bump steer, and you can find/build kits to correct it, but its a PITA.

Your control arms, and steering/toe arms are never really all perfectly setup to negate that.
