Default too much front end grip

I am using the rear motor car, set up like Dustin Evans, driving on clay with quite a few dust, 4rips and holeshots
The car has quite lots of steering and is super hard to drive you have to be very patiant not to spin out.
Feels like there is too much front end grip.
I tried a few changes that made it better but not perfect. (inner shock position front, outer rear, 10 degree front caster)

Do you limit the steering end points and use much expo ?

I am very confused because I didnt have problems with other cars on this track and tires

Where is it too much?

Corner Entry, Mid Corner, Corner Exit ?

All require a slightly different approach...

I would say everywhere, but the worst seems to be the corner exit (and everything on power is very very hard to drive). The corner at the end of the straight off power is not a big problem.

Softer rear springs, rear tires that offer more grip.

Yes, limit steering and use front expo (I set my own typically so I can only do a complete u-turn in one lane of the track's width).

Maybe you could try Darrenīs front mod as seen on page two and three here:

http://www.oople.com/forums/showthre...t=90035&page=2

Itīs made for mid motor but obviously to have less steering coming out of a turn so maybe could work for you, too. The little trimming and "stretched" standard length turnbuckles just to test it should give you an impression if itīs any good without having to buy longer ones for racing.
Besides that and setup/ tyres I would doublecheck the diff just to make sure it isnīt responsible for the undesired cornering.

sounds like the rear is lacking grip as apose to front end having too much


try more rear toe in
shorten wheelbase
reduce antisquat
move cell to fully rear

try rear shock on inner on wbone
front shock outer on wbone

white rr springs
silver or green front springs


this should really help to numb the car hopefully this will give u a starting point where you could start to dial some steering back in

Im using the RCRD -5 Chassis with the truck 30deg front block and zero caster block. The more kickup transfer more weight in the back on power and seems to help my car on corner exit. I also have weight on top and in the front of the tranny. My car finally has the same level of traction as my teamc Evo. I had good success with the yellow rear spring but I'll try the white next race day.

Hi, just by putting the -5 chassis without any other changes, how did you find the steering? more, less ? less stable, more?

I would assume a shorter chassis will just exaggerate the cars steering
