Coming from someone who scales and adjusts ride height and corner weight of his car, if you went from no power steering and no AC to the same thing, and MT to MT, you will be exactly 106lbs more, adding 4.78% weight to your car, and less that 1.5% the front wheels, that is like taking a 14 year old car out in your car. You will not notice a thing.
(if you went from a d16, to a b16 the difference is 94lbs)
Have fun, and buy a LSD before you have to buy new tires.
