The NC was a pretty rigid little car when it was introduced, but time moves on. As cars age, their chassis loosens up. A floppy chassis means less precision, more rattles and decreased ride quality as the chassis bends instead of letting the suspension deal with it.
IL Motorsports has developed this X as a replacement for the weedy little factory one. This will make a big difference to the rigidity of the chassis by "closing the box" under the car. Loss of ground clearance is minimal and the powdercoated aluminum won't rust.
Fits all manual and automatic transmission NCs. Compatible with V8s as well as four cylinder cars.
