Is my Autox 914 too stiff?
I am currently running the PO setup, the 914 was set up for club racing with front and rear coil overs. The front is at 330lbs/in which I believe is the equivalent to 25MM torsion bars and the rear is at 230. The 914 is a 4 weighting approx 1780lbs with bias ply slicks. I plan on switching to Dot-R radials. I have always thought for autox go soft on springs and big on bars. Does the paddock crowd have any suggestions for a setup. The autox sites in NYC tend to be on the rough side. I was thinking either 175 lbs/in in front and 140 lbs/in rear or 200 lbs/in front and 180 lbs/in rear. |

Use charts as reference to get yourself in the neighborhood. Every 914 handles
differently under the same settings and every driver has their own style. Test, adjust, test, adjust, test and accept changes using your own ass. There are so many variables. But, you know that... What works great at Sebring, sucks at Lime Rock. If you think tires are important, try asking someone what pressures they're running. |
