According to Tein USA, they have finished the testing phase for the Kia Forte Koup coilovers and are ready to reveal the drop. The ride height drop for the Koup will be 35mm in the front and 25 mm in the rear. Different car packages may effect the weight of the car, therefore the actual drop may vary. Judging by the pictures, it seems like a perfect drop.
