Use this adjustable trailing link from SPC Performance to make the rear of your Infiniti Q50 or Q70 fully adjustable for set-back / wheel base. The remove and replace link will provide +-1" movement to adjust for other suspension modifications, be ready for the track, or simply to replace the stock non-adjustable arm. This link features a high durometer bonded rubber bushing to maintain factory ride quality and all steel construction for strength when you need it. Consider adjustable toe arm p/n 72255, adjustable camber arm p/n 72245 or the three arm set p/n 72240 to make your suspension fully adjustable. California Residents WARNING
