Sway Bars VS Camber plates

[BraveUlysses]

Do you already have good tires?

If you can do camber plates AND a front sway, you'll be set.

[T Verdier]

So keep the rear sway stock and get a thicker front one? That sounds like massive under steer to me but maybe I'm wrong.

larger front sway bars will give more understeer but will improve steering response

[5KWattson]

larger front=understeer
larger rear=oversteer

camber plates= adjustable caster/camber= caster is guna help your steering depending on how you set it, for slow speeds or high speeds

[!kid]

+ caster= better straight line stability but harder to turn in
- caster = better turn in but loose straight line stability and the car will tend to wonder on straights

i say get camber/caster plates then you can play with all kinds of settings to find what works best for you and improves your times

Sorry, but that's incorrect. On e30's, as well as many other cars, a thicker front bar will actually increase front end grip, giving less understeer, due to increasing the front tires contact patch.

care to go more into detail because as many years ive been into cars i have always thought that it was how it was stated before

"The balance (and grip increase) of the car could also be achieved by reducing the front swaybar stiffness"

no offense but i would like to hear the defense on this, how is it that a e30 is different from every other car street car in the entire world, now we are talking about autoX but still technically a street car(not circle track) so if please inform us.

you missed this point

due to increasing the front tires contact patch.

You are wrong in this case.

larger front sway bars will give more understeer

larger front=understeer
larger rear=oversteer

That assumes the car already has an ideal suspension geometry. Our cars don't. Like all cars with MacPherson struts, E30s need all the roll stiffness they can get.

Exactly. A stiffer front bar keeps the tire from rolling over, which is where your loss of front grip is coming from.

i am so lost right now hahah

This whole thread has been discussed before, for those who would like to search.

If not, carry on.

I definitely noticed more front grip when I went to a bigger front sway, and this is at stock ride height (with a better camber curve). Probably also involves the shot bushings that were on the old one.

On its own with ideal suspension geometry, increasing the lateral load transfer on one axle by increasing sway bar size or spring rate will decrease that particular axle's absolute grip.

However, with our macpherson struts, at a lowered ride height we lose negative camber the more our front suspension is compressed (camber curve has decreasing negative camber slope), so as previously stated, a lowered car needs all the roll stiffness it can get. As for the rear bar, more rear sway will increase tendency for the rear to swing around, make your LSD's job harder (if you've got a worn-out unit like me) and basically make it harder for your car to put power down on corner exit. However it's definitely helpful in tight corners.

alright well if thats the case i did miss the point i drive my benz alot more so i always forget the 30 has a different front suspension, my bad but i see now why it is how it is
