CompG Package makes big difference

ReviewMy GP is equipped with the CompG performance package which includes: Head Up Display, Tap Shift, higher gear ratios, stiffer rear sway bar, and red brake calipers, maybe a few other things. The gear ratios dramatically improve acceleration and the sway bar makes this thing handle like a dream. It still maintains a quiet comfortable ride on the highway but is rigid during spirited driving. My biggest complaint about the car is the shifting performance in standard automatic mode, it just doesn't downshift quickly enough and lets the RPM fall well below the power band before it switches to a lower gear. This is alleviated by the Tap Shift system which will let you shift manually.
Best FeaturesLots of power, HUD, Heated seats, steering wheel radio controls, 17" 10 spoke alloy wheels are beautiful and are set off by red calipers. Traction and stability control work great without being intrusive. Handling is superb, tap shift helps accelerate out of curves. Large trunk. 29 mpg hwy 18 city.
Worst FeaturesPerformance: Shifting parameters should be changed to make it downshift sooner. Appearance: Spoiler should be wider, front fascia should extend lower. Comfort: front seats could be a little wider. Misc: Wish it didn't require high octane gas but that's what you get with a supercharged car.
