GTR vs. GPL setup controversy
Hi folks, I found the following quote on the BHM site, apparently from
some gpl setup guide: "There are front and rear sway bars. These suspension devices prevent the suspension in "rolling or leaning" in the process of turning. Usage: ARBs are used in the "apex" area of the turn. If the car is exhibiting an "understeer" problem in the apex of the turn, "increase more front ARB". OR "decrease rear ARB". If the car is exhibiting an "oversteer" condition in the apex, "decrease front ARB" OR "increase rear ARB"." While the Motec beginner's guide for GTR claims: The general rule for setting the anti-roll bars is: More front anti-roll bar = understeer and worse turn-in but more precise handling Less front anti-roll bar = oversteer and better turn-in but less precise handling More rear anti-roll bar = oversteer and better turn-in to corners Less rear anti-roll bar = understeer and worse turn-in to corners So who's right and who's wrong? Please enlighten me! ;-) Cheers, uwe -- GPG Fingerprint: 2E 13 20 22 9A 3F 63 7F 67 6F E9 B1 A8 36 A4 61 |

GTR is right; BHM is wrong.

Yep, unless "more ARB" means "softer ARB", hehehe
And the ARBs are working whenever the car is not moving in a line, i.e. not only at apex. The apex period of a turn, or the "constant speed" period can be almost non-existant. The ARBs have an impact on car behaviour during most of the turn nevertheless... ---A--- Steve Smith wrote: > GTR is right; BHM is wrong. > > "Uwe Schürkamp" > wrote in message > ... > >>Hi folks, I found the following quote on the BHM site, apparently from >>some gpl setup guide: >> >>"There are front and rear sway bars.

At the turn-in moment, or at the apex dampers have more effect, so ARB may not be much noticeable. Not sure where GPL quote comes from, but in GPL it works correctly. Like GTR guide says. Alex. |

I think that article was written long before all things were know about GPL.
The article has been edited so as not to create confusion if someone were to read it today.
