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. |

(IMG:style_emoticons/default/confused24.gif) What you've described is the very essence of understeer. 19mm is a lot of front bar that can lead to understeer. Especially so without a lot of rear spring or rear bar behind it to balance it. (IMG:style_emoticons/default/popcorn[1].gif) |

(IMG:style_emoticons/default/popcorn[1].gif) I guess it is possible that if I pushed it harder it could turn into noticeable oversteer but it just does not feel like understeer that I have experienced before. Need find out what springs are in the rear now. Can you tell by diameter? I used to drive this on the street, talk about oversteer.
