Yeah you definitely dont need that stuff, Sometimes its better on certain cars, But not on this or some like it.
Its not every day you hear a Pro Race driver call a car Perfect, A Camaro to, Im still at odds with it, And its twice as much as a 1LE, And the looks are my only concern.
And newer isnt always better, Its some what of a shame people try to move to the future at an unprecedented pace rather then just enjoy the present(But i can certainly understand wanting to move ahead with better things.)
