Hey offroading guys! (a little height joke... ) Here is a DIY installation guide of our GT-F lowering springs. Please note the color of the springs in the photos is a test color. GT-F springs are orange. Tools needed: 10mm socket 13mm socket 17mm socket 19mm socket 17mm crescent wrench ---------------- To prepare for the spring installment have your car on the lift or jack stands with all 4 wheels off the ground and have the hood open. If you cannot have all four wheels off the ground at the same time we recommend at least two wheels off the ground. Front as a pair and/or rear as a pair. Remove your wheels and set aside. Starting in the rear, we must first disconnect the headlight sensor on the driver side by popping the clip out to release the sensor. A 10mm socket is then used to unbolt and remove the cover underneath the lower control arm. Use the 17mm socket to remove the linkage bolt connecting lower control arm to the strut. Then unclip the suspension sensor on the strut. Next remove the ABS sensor with a 10mm socket. Switch to a 13mm socket to remove the bracket for the suspension sensors and position it off to the side. Brace the rear lower control arm from underneath for your safety. Then, using a 19mm wrench and impact gun, remove the 2 bolts on the lower control arm connecting the LCA to the strut and the knuckle. Pull down rear lower control arm and remove spring. To reassemble follow the steps in reverse making sure that the spring is seated flush in the groove on the lower control arm with the rubber mount replaced on top. Be sure to brace the lower control arm before tightening the strut tower and rear knuckle. Moving to the front of the car. A 10mm socket is used to remove the brake line bracket on the engine side of the strut. A 10mm socket is going to be used to remove the bracket behind the caliper towards the front of the car. Then switch to a 13mm socket to remove the bolt for the bracket above. This allows you to move the wiring out of the way in order to unclip the sensor behind the strut. Use a 17mm socket to remove lower strut bolts. We sprayed WD-40 around the strut bolts so that they would slide out easier. The lubricant is optional.
