When driving large sweepers like freeway on ramps at high speed I experience what I can only describe as front end scrubbing. Not understeer, more like the front is just not planted and tracking. Things get better with a full tank of fuel. Is that just the nature of the 914, full tank factored into weight bias, or can the suspension be tuned to emulate the weight.
Here is what Im working with; -19mm adjustable sway-bar set about 1” back from full soft. -Koni yellow adjustable shocks -Stock front torsions -Rear springs are aftermarket (reddish orange color) but I do not know the poundage. Any input would be appreciated. |

A bit thicker than 9.6mm but close accounting for coating thicknes. |

Here's the photo of 914Rubber 100 lb/in springs and measurement. A bit thicker than 9.6mm but close accounting for coating thicknes. My springs measure at 10.4mm in diameter so i am guessing 100lb? I found the attached chart that shows the stock spring specs. This weekend I loosened up the front swaybar all the way and took a drive through Santiago and Trabuco canyons. The bar is a GPR 19mm and at full soft is supposed to be close to the stock rate. This really loosened up the front end in general. Steering feels lighter and less controlled, but smoother for sure. Gonna hit the sweepers this afternoon on my way home and see what is does. How low does the car have to be to experience bump steer? Attached thumbnail(s) |
