My car has a push at high speed in tight corners. (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) It wants to slide the front to the outside of the circle. I need to increase front grip. I was talking to a local car guy here and he told me I should has a big rear sway bar. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) I tend to believe him. (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) He used to work for the Archer Brothers in their race shop. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) But maybe his theory doesn't apply to middle motor cars. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)
Who has experience with this? Show me your sway bars. Specially rear ones. Oh ya, what about tire pressure. I encourage long explainations. But talk to me like I'm a 4th grader. (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) |

The way this swaybar thing was explained to me was:
The more compliant (softer) end of the car has load distributed more evenly between the inside and outside 'tiars' -- more grip. The harder end puts more load on a single 'tiar', causing it to come unstuck sooner. Since the front is pushing (sliding first), it has a higher spring rate. The options are 1) Decrease the spring rate in the front either by changing out torsion bars, or softening up the swaybar by moving the droplinks farther out on the adjuster arm. or 2) Increase spring rate in the rear by adding heavier springs, or adding a swaybar. Heavier springs is probably easier. You don't necessarily need a rear swaybar. I took my 914 from stable, to extremely tail-slide happy by using 200lb springs in the rear. This has since been fixed by adding a Tarett bar in the front. (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif) |
