Is it time to improve your high horsepower Porsche 997 turbo;s handling? Vivid racing has this incredible street suspension package proven to give your car improved handling on the street while maintaining comfortable characteristics. The all wheel drive is notorious for pushing in turns and having alot of pitch and dive under driving conditions. We have packaged the bilstein pss10 coilovers and the agency power adjustable sway bars to eliminate these problems. The bilstein pss10 coilovers work with the pasm system to offer you on the fly adjustability between soft and stiff settings. The spring rates are around 250lbs/in on the front and about 480lbs/in on the rear. Because the coilovers use helper springs, they are very absorbant to daily driving road conditions. These coilovers will perform ok for occasional spirited driving or weekend drivers eduction events. To help keep the chassis flat in the turns and reduce the under steer problems on the 997 turbo, we add the front 25mm adjustable sway bar and rear 24mm adjustable sway bar from agency power. These sway bars feature 3 settings on each bar to help give your car a well balanced handling characteristic. We generally recommend running the rear on the stiffer setting and the front on the middle. This will help give you more over steer. For a street car, a basic alignment is all that is needed. With these coilovers you can run the car at the stock ride height down to about a 1.5 inch drop.
