Hey 914ers:
If you have been following my posts on 914 chassis settings, here is one that applies to ALL 914's. To start, per my posts: -I Squared the chassis with paralleled strings to measure and set the toe, front and rear. (Front = 0 to -1/16 toe, rear = 0 to -1/8" toe) =Results: steering a bit "nervous", but all else stable. -Camber: For Street cars, Standard front with -1 to -1.5 degrees rear. =Results: nothing noticeable. -I bumpsteered the front suspensions to within 0.008" from prefect at 2" compression. =Results: nothing I could feel driving the car on the street. TBD on-track. -CORNER WEIGHT BALANCED THE CHASSIS: With the car weighted for the driver weight, I adjusted the rear spring ht. and the front torsion bar ride height. For the rear, large diameter washers can be added to make adjustments, while the front is too easy with an 11 mm wrench. =Results: WONDERFUL!! With all the previous chassis settings done, the car still wanted to pull to the right as though I were on a highly crowned road. After the balancing the corner weights, side-to-side, the car now runs STRAIGHT and TRUE right down the road. The sense through the steering is now light, equal and very linear as to where I want to aim the car. Conclusion: Take the time to either build wt check lever, as per my photo or find a very strong STEEL ladder and wing it. Regardless, the benefit from the effort is completely WORTH IT!!! If you have any questions, please let me know! Terry stewteral@verizon.net |

Your slicks won't like that much camber. About half as much is typical.
I wouldn't use that much toe out up front. The car might turn in real nice but I think there will be a lot of drag on the straights, the car will have a tendency to wander. Your front ride height seems way too low to me. And why run the rear starting psi so high. The rears heat up faster so I typically have them set 1/2psi lower than the fronts. |
