So, I've been driving the 914 alot more lately (side story to that). And I've noticed since my last alignment that the car seems to have a bit of understeer*
* To clarify, am I correct in saying under-steer is when you turn the steering wheel and the car does not immediately turn (plows a bit)? So, here's what I got: Boges all around. 23mm Adjustable bar up front. Stock rear bar. Stock tortion bars up front. 120lb springs in back. Rear ride hieght is 5½" from ground to rockers. Front ride height is 4½" from ground to rockers. I do not have money to throw at a solution. I very much would like to keep the rear bar as it does keep the car very stable in wide wide WIDE turns that I like to take very fast. I guess I'm asking, how should I adjust this? Stiffen the front bar? Run it "softer"? Level the car out front and rear? I do not have adjustable perches in the back (consider it stock hardware). New shocks are not an option. When I was running with the front bar alone, I noticed the front of car would stay flat in very tight turns but would plow a little bit -- give it enough gas and it would straighten the ass-end out in the direction I want, when I added the rear bar it made the whole car stay level in turns, but the understeer* remained, was a bit more noticeable. Any suggestions, please fire away. Thanks. I know I'm crazy, but I can't spare any pennies on my cars for some time. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) |

yes, that does seem counter-intuitive (sp?) at first, one would think that raising the front would make the understeer even worse (which is true), BUT if your car is too low in the front and you run out of shock travel on hard cornering, your front spring rate effectively goes up to infinity, making it infinite STIFF, in which case the rear sticks and the front slides ... make sure you got adequate shock travel in the front before you do any major changes to your suspension. raise the front 1/2" and see if that makes any difference ...
