While using the Saturn SKY Red Line build-your-own site I noticed an option called "Performance Suspension Kit" for $1,584 described as follows: "The performance suspension kit allows the SKY to carve tighter corners with even more precision. Includes front and rear stabilizer bars, bushings and sport-tuned, coil-over Bilstein monotube shocks." Now since the Red Line is due to have an upgraded suspension including "four-wheel independent SLA suspension with coil-over Bilstein monotube shocks" just what does the Performance Suspension Kit option achieve? I placed my order last week but was not aware of that option and would like some information before spending $1,600! I plan on having fun with my R/L and will drive aggressively at times but don't intend on racing or competitive events. Any help would be appreciated.
