I have gotten to the point where I need to consider the spring rate. The rear trailing arms are in with true 5 lug hubs, 911 brakes, and some reinforcement. The shocks are bilstein sport. It is a road car with 16 in wheels running no flares so the tire size will be 205.
I have the original springs from the 1972 four cylinder donor. So ladies and gentlemen, please help me with shopping, or not shopping. Thank you! |

I run a 2.8 with more horsepower then a stock 3.2. For the track I would suggest 350 in the front and 220 in the rear. Coil overs in the front if they are affordable to you. Good balance. 914 unlike 911s need more front spring. I have dabbled with all types racing for the last several years and this is what the imsa cars raced with back in the day. If it is for a street car I would soften it up a bunch, but for pure racing this is the combo that works.
