2000 Honda Civic Si lowered with 17" wheels rides rough?

[reb422]

I just bought a used 2000 Civic Si. It has been lowered in the front with what my mechanic called "coil over" suspension. It also had the factory wheels replaced with 17" wheels. This car is nice but rides really rough (bumpy, hard hitting on holes in the road). I suppose the larger wheels and lowered vehicle look decent, but why would anyone want to do this to a vehicle? Is there any advantage other than looks? Anything else I should know or expect from this type of suspension or wheel size? Also, is there anything I can do to make this ride a little smoother? Thanks.

Unlower it, and put factory spec wheels on. It will ride like a dream then. If you want a good handling car, buy a "sports" car.

The rough ride is due to the lower profile tires, but mostly due to the higher spring rate (stiffer spings and shocks) of the new suspension. Stiffer suspension is necessary when a car is lowered to avoid "bottoming out" the vehicle over bumps and causing damage. The higher spring rate also improves handling. Check with the mechanic to see if the coil overs that were installed are adjustable. If so, you may be able you improve the ride quality some without giving up too much handling or the look of the lower ride height. So, if you like the look of the lower ride height and enjoy the improved handling, then the rougher ride may be worth it.
