RX-7 Adjustable Front Lower Control Arms add a new dimension of adjustability to your car. In order to get the most from your 1979-1986 RX-7's chassis, you need camber adjustability. Racers know that even with moderate size radial tires, it is possible to get improved front cornering power by increasing the camber to four or five degrees. While tire wear at this setting is high, the camber can be changed quite easily after initial setup with this kit, adjusting from race to street setting easily. This kit also allows you to correct an error in your chassis, or to pre-set incremental negative camber for better handling all the time (we recommend .5 degrees negative camber maximum for continuous use). These arms can be shortened up to .5-inch from stock (approximately 1.3 degrees more positive camber than stock) or lengthened up to 1.625-inches from stock (approximately 4.4 degrees more negative camber than stock). The original rubber inner joint is retained to isolate road shocks and noise. When front wheel negative camber is increased with this kit, there is a possibility that the front tire may contact the fender under some combination of bump and turn. This is especially true if wider-than stock wheels and tires are fitted. It is the user's responsibility to determine that there is adequate clearance for his application. Price is for a pair.
