So I am just begining to see why people always sa race cars are never done. I just ran my first autocross on track tires (Nitto NT-01s) and now my previously perfect handeling car lifts front wheels way into the air. Corner workers were saying as high as six inches!!! Now I am NO expert but this leads me to believe that there is still a considerable amount of time to be had if I can keep the wheels on or alot nearer to the ground. My question is how stiff to go in the rears. I currently have #140 Weltmeisters on the back and stock front torshens with a H&H 19mm ajustable front sway bar set one hole from soft leaving two stiffer settings (four holes total). I am thinking #175 or #200 2.5inch springs on ajustable perches. Any suggestions? Will ajusting the front bar to full stiff be enough to counteract springs this stiff? This is for a strictly autocross car that only gets driven to events and on the occassional sunny day. Also it has a six pt. cage.
Any input will be appriciated since I would only like to buy one more set of springs. Attached File(s) 914.htm ( 17.47k ) Number of downloads: 194 9142.htm ( 17.49k ) Number of downloads: 200 |

I know all about beating "faster" cars. At the last autocross out here at El Toro I turned in the fastest time for a 914 and placed 15th out of 100 on times alone. I would like to improve the handeling of the car without changing the front except for stiffening up the sway bar. Has eneyone succesfully run #200 springs without adding stiffer torshenbars. I think that these stiffer springs would really help keep the car flat but I do not want the car to push or have uncontrolable overstear because it goes very neutrally the way it is set up now with the same air pressure front and rear.

Has eneyone succesfully run #200 springs without adding stiffer torshenbars. The only way you'll keep the car balanced with those is to put a really immense sway bar up front. Which will increase the tendency to lift the inside front wheel--though not by as much as the stiff rear springs will reduce it... QUOTE I think that these stiffer springs would really help keep the car flat but I do not want the car to push or have uncontrolable overstear because it goes very neutrally the way it is set up now with the same air pressure front and rear. If you like the way the car is set up now, I suggest leaving it that way. Lifting a front tire isn't necessarily good, but frankly it isn't hugely bad either. Lots of cars do, except of course for the front-wheel-drivers which assume the "pissing dog" attitude... (IMG:style_emoticons/default/wink.gif) If you really want to cut down on the wheel lift, you will probably have to go with stiffer rear springs and stiffer front torsion bars. You might even want to be able to back off the sway bar to its softest setting... --DD |
