For several months now the wife and I have noticed a serious discrepancy in the handling of our 328xi upon breaking. The car pulls to the right and the effort of this pull is determined by speed and encouragement from the applicator's effort. I can assume that there is something amiss in the front suspension/steering mechanics and my question is simple. Once the problem is diagnosed, is there a possibility of stepping up the suspension for more durable and responsive gratification? Are there 'upgrades' for the suspension that I should be looking for?
