The COBB 2008+ Nissan GT-R Sport Spring Kit is the best first step to a better handling and better looking car. The 0.8" drop front and 0.5" drop rear lowers the car's center of gravity to improve cornering speed and response while also minimizing wheel gap for a sportier look. This aggressive stance reduces squat and wheel hop under hard acceleration. Progressive spring rates of 400-968 lbs/in front and 188-485 lbs/in rear provide the sport feel without being unnecessarily harsh or bouncy. Road course tested and real world approved, the COBB Sport Spring Kit is the best direct replacement spring available for your 2008+ Nissan GT-R.
