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 |

Of course, sonny, you can't learn squat from a fat old guy.

Of course, sonny, you can't learn squat from a fat old guy. Hey Ricky Racer, Are you saying you have a lot of racing and race-car prep experience? I'd be interested in learning what experience you have with which cars and tracks. Have you always done your own chassis prep and tuning? What kind of equipment do you use for chassis alignment? Have you raced a number of different types of cars? Do you have any special tricks you have picked up over the years? Thanks, Terry |

Do you have any special tricks you have picked up over the years? I'm not Ricky Racer nor do i play him on TV ... (IMG:style_emoticons/default/biggrin.gif) I happen to be the crew chief for a small Porsche racing team. We consistently place in the top 3 with many, many race wins and overall class wins under our belt. To answer your questions: - All the chassis prep and tuning is done by us. - We use electronic scales and the Smart Racing strings, camber plates and camber gauges for alignment. - I race and work mostly on Porsche's. 911, GT2, 914, Boxster, you get the idea. - Yes. My point? I agree with the old fart. You're doing it in reverse. We always start by setting the ride height close to where we want it, then corner balance the car to fine tune, then align the car. In that order. (IMG:style_emoticons/default/popcorn[1].gif) Andy |

Since every adjustment effects the others, it is a continuing process of refining all the settings. Now after setting toe, camber, ride height and corner weight, I will go back and verify toe and camber settings. Have fun with your track cars, you have 2 truly great tracks up in NOCAL, while I have only WSIR and Buttonwillow here in SOCAL Best, Terry |
