Get the ride you want - adjustable ride height and ride comfort. What a difference!
Recommended by owner of Aurora #151 - Carrera Shocks, now owned by QA1, offer ideal adjustable comfort, ride height and low cost by direct replacement of your stock shocks. These are aluminum body, threaded shocks with silicon polyurethane mount bushings. The knob at the bottom allows 12 different softness settings, and with special wrenches, the collar adjusts the ride height.
The Aurora GRX suspension differs from the Mark II. The longer replacement springs and shocks are shown below. Note - the GRX here has 195-65-16 tires all 'round, so the car rides higher than with the factory spec tires. Dimensions may vary with your car, so It's best to order shocks and springs through your mechanic. He can exchange if necessary, but the products below worked well for Auroras Mark II #110 and GRX #48.
Aurora Mark II
Stock fronts have full length springs, which will need to be replaced with shorter ones to accomodate the position of the adjustment ring on the new shock.
Front - QA1 shock number DR5855P and spring is 12" x 250lbs.
Rear - QA1 shock number DR8855P with stock 250lbs spring
Front - QA1 shock number DR7855P - springs 14" x 225 lbs
Rear - QA1 shock number DR8855P - springs 14" x 275 lbs.
Aurora had to meet DOT bumper height requirements, so the front is quite raised - not a great look. When you adjust the front down to a natural position, your undercarriange clearance is reduced, but more importantly, your steering rack drops lower than the rod ends, causing bump steer. Very bad. Best fix is to shim up your rack so the rods are level, and then get it realigned. See the photo of #110. I had to bracket out the bottom of the radiator so the fan clears the new rack position.
