That's the problem. Each model should have parts specificaly designed for it. Suspension probably being the most important since it controls how your car behaves under certain situations. Ever hear people complain that the front of their car is higher or lower than the rear? Probably cause their springs were designed for another car but marketed to fit several applications. Use springs that were initially designed for an Integra and what do you get? A tailhappy Civic. Not good if you're a novice driver.
