at our track losi block heads, taper pins & jconcepts double dees work well at the front.

rears losi x2000

try 2wd bobcats hard (clay) compound at the front

So far, I have used the smallest pistons & AE blue front springs to stiffen up the front end. Also moved one hole out on the front shock tower. 35wt oil.

On the rear, I have used 30wt oil, standard spring, moved one hole in on rear tower.

ride height 1mm higher at front at 23mm and 22mm rear.

front diff is tighter than rear, no slippage.

I will use a heavier oil in the front next time.

Is there anything else I can do to tame down the steering? Maybe front stabilizer?

moving the shock out on the front tower will make the car react quicker thus giving you more initial steering but less though and out the corner you havent said where the car is oversteering is it does it have to much intial steering ie the first steering input as you get to the end of the straight etc or does the car break away after you have it turned in and then breaks away or does it happen when you get back on the gas to come out the corner is the car oversteering going around the sweepers and you are having to get of the throttle. until we know this there is n ot much point of changing the car except for self experiment.

oversteering when off power entering turns.

alot of times im counter steering entering turns as the back end is trying to come around when entering the turn. Looks good and all, but not good for lap times Mid corner and exit is good, just off power entering is where I would like it corrected.

just put some 40wt oil in the front, just need to wait for another day at the track.

501x stabilizer set on the way too. I will just use the fronts

I just thought that moving the front tower out one hole would make it stiffer

[discostu]

in that case putting a stiffer spring on and standing the shocks up on the tower will make the car worse you need to make the front end of the car more progressive you can achieve this in a couple of ways if you lay the front shcoks down yes it will make the car slightly softer in its damping but the shocks will not react as fast so it will be easier to turn the car into the corner with out oversteer you can also move the shocks out on the lower arm this will do a simular thing but with greater effect as you would be changing the point of leaverage by a greater amount.

yes it does but it will also get to the shocks point of no more travel quicker hense make the car react faster. if you look at carpet racing where the grip is very high the shocks are layed down to stop grip roll. grip roll is produce from the edge of the tire biting into the track to much the only way to stop this is to make the car more progressive slowing the reaction of the car down and on initial steering input.

your not getting grip roll but you are getting lots of inital oversteer if the grip was higher you probably would start lifting wheels.

does this make sense

How much camber are you running on the rear?

thank you, you sound like you know what your talking about

I was just going on by what I have been reading on the db01 forums. Too much steering, stiffen the front end, springs, geometry etc.

I've got much to learn about car setup.

I usually run -1.5mm all around, but since have used 0 at the front lately

the thing about car setups no one thing will cure the problem a change will always effect somthing else also everybody see what the car is doing is different and discribe in a different way. the books and manual are very good but they tend to say this change will do this not taking into the account of track type and conditions and the rest of the setup.

i dont think you are running enough camber dont forget its an offroad car and you get a lot of suspention travel and camber change and roll.
