Status: offline 		I'm just wondering how most people setup their cars to match their driving style

ie, do they make the car naturally over or understeer?
And, also when turning into a corner do people always use full lock? Or is it better to setup the rear stiffer and use less steering input?

My car is weird. At low speed power out of corners it oversteers, at higher speed power out of corners it understeers, and it lift off oversteers pretty hard too
I have hard springs + swaybar at the front and soft springs no swaybar at the rear

And I use the Tamiya slicks on it
If I make the rear stiffer, it oversteers too much on lift off
It kinda under and oversteers depending on the situation

Status: offline 		let me tell you a secret!!! the front of the car always has more grip than the rear. also the best thing to do is to have harder springs on the front and a litlle bit softer spring on the rear. i most of the time use the tire shore to adjust the car to my driving style and also to get rid of grip on the front.

Status: offline 		Yeah their grip levels seem to be low and the compound seems hard
It does have innfer foams though (I put some stiff ones)

I am looking at the HPI slicks, would they grip better?

Foams war out too quick + I can only find them for $50 USD a set as opposed to $18 USD a set for Tamiya Slicks or $15 USD a set for HPI slicks
Remember the tyre size is an odd one on this car

Cypriot boy, the front is already much stiffer than the rear. I run hard springs + swaybar front, and soft springs - swaybar rear

Status: offline 		Depending on the corner, I let go of the throttle going into it, hold it steady through, and throttle it out of the corner
It's weird, sometimes I oversteer on throttle, sometimes I understeer...
For example, if I go into a corner with some throttle, it will understeer
But if I lift off and turn sharply it spins out

What do you suggest? Hard front, medium rear?
Swaybars?

Status: offline 		yes, and also put a hared silicon oil on the front rather than the back. now as for the sway bars you will have to expiriment. i would say very soft on the front sway bar and a harder one on the back. also do you go down at the track??

Status: offline 		Take off the swaybars for now, and set your ride height 5mm front and 5.5-6mm rear(lower fr/rear if you have a smooth track). Drive it and see how it goes. If it turns in very hard, but pushes exiting, give it more toe in up front. If it pushes going into a corner but gets looser exiting, give it less toe in up front. A good starting point is 1 degree toe in and see how it handles, and adjust from there. My car handles well for me with .5-1.0 degrees toe out front, but each car and driver and track is different so experiment. Now lift the rear end with a knife point or similar thing from chassis center and see which tire lifts first. If the right side lifts first all the time, increase preload on the right side or decrease preload on left side. Same in front, the idea is to balance the car out as much as possible. If rear toe is adjustable, make sure they are set the same, about 1degree toe in is usually good. Any less and it gets really loose. After all that, watch how your body rolls in the turns. Does it roll so much the chassis scrapes the asphalt or is it a high traction surface? If so then put the swaybars back on. On low traction surfaces swaybars don't help much and you might as well lose the dead weight. Hope this helps somewhat, definately wont hurt to check everything over setup wise and start with a good baseline. An even, balanced car is always a good place to start, and lets you check for hidden damage as you set it up. Good luck!

Status: offline 		Thanks for the advice
The car is for bashing though one day surely I'll hit the track for fun

The oil in the diffs is the same front and rear (must be around 100K or so) but I have a bottle of 50K which I will end up putting in the rear
As far as preload goes, I have just enough spacers on all shocks such that when I put the car onto the groun, there is the tiniest bit of downtravel from the weight of the car
