In your opinion what suspension upgrades make the biggest difference in a cars performance? I know the most obvious one is tires so lets leave that one out. Whadya think? Coilovers and adjustable shocks? Tie/Sway bars?

 

shocks
springs
bars

in that order

 

its all gonna depend on the car its balance its weight its chasis its weaknesses its suspension design its drivewheels its too vague of a question it could be different for different cars.

 

also depends what youre trying to get the car to do.

 

My 99 Si and Im looking for AutoX performance.
