The real reason our cars understeer

Suspension and other discussion

Postby GTfour@alltrac.net » Fri May 23, 2008 12:29 am

ok i'm sure suspension gurus like racefiend will rip into me for posting without having a clue about what i'm saying but from what i gather (and i admit its not much) a harder rear anti-roll bar will not take away the understeer problem in the way we would like. it would simply cancel it with oversteer. so in a sense you get rid of the understeer but is this the ideal solution? this is what i wish i had answers to. concrete answers

softer front springs would also mean that you would need a larger diameter front antiroll bar which seems to contradict trend in higher performance race cars which seem to prefer more spring rate and less anti-roll bar.

as for changing the torque split ratio front to rear im not sure that its possible to change it. i always assumed it was fixed at 50/50 permanently. but if this is not so i would also expect less push under effect from a 60% rear torque split.
but then again i dunno what the hell i'm talking about right? lol

I think the biggest reason why the car understeers is the weight ratio.

Just out of interest, do those of you with an ST165 experience understeer issues?

any posts on these forums outlining the front/rear weight distribution of the alltracs? 165 185 and 205?

The most typical weight distribution is 60/40. Some have managed to adjust that some. I think mine had a little less weight bias to the front when I corner weighted it.
