I will have to play with that this weekend TeamGP. So by the sounds of it, it is not the steering throw so much as it is the ackerman causing the wheel hop. Someday when you at at the track, I need for you to explain how ackerman effects the car. That is one area I never really dug into or understood very well. In oval, there never really was a need for it.

I'm seeing 20-22deg on the inside wheel, and about 3deg less on the outside. This is for a small and tight carpet track. On a large and flowing carpet track I had less than this.

Ditto on that one i'll be getting my gauges out as soon as i get in from work and see what the effects are if i'm understanding it right you should be able to gain corner speed by reducing the angle difference between the two wheels and limiting the scrub on the inside wheel
thanks teamgp

To acheive your 16.5d on the inside tyre i had to turn down the dual rate from 100% down to 65% now if i did that, to me you are NEVER gunna have enough steering / steering lock.Am i setting it up wrong or do you guys always turn the steering down that much.
Also my xray is kit set up in regaurds to ackerman and i set it up so 100% steering throw just touches the carster blocks and the 27d inside tyre and 18d on the outside is what it reads at kit.
What are everybodies thoughts.
cheers.
Some drivers, especially the old school ones that started before all this techno handheld gadgetry, have their EPA/dual rate turned up way high. However, they never really use the full steering throw, unless they're facing a wall and need to turn around within 2 feet.

With rubber tires on asphalt, I have used upwards of 22d/17d in the past and the car drove ok. But when I turned it down to 16.5d/14.0d and changed the setup to gain steering, corner speed went up and lap times went down.

Some setups will work with a lot of steering throw. But some cars dogbones, like the T2's, won't allow a lot without excessive chatter.

Yep. Move the servo saver forward and/or the arm positions backward to reduce ackermann effect and then reset your front toe-out as it will change.

No no no... it's when you take the wheel off, the hex goes with it, AND the drive pin falls out into your carpet never to be found again! Thats when I start throwing stuff hahaha.

the fastest driver at my lhs puts his car in the tightest lane of the track and sets his dual rate to be able to make a full circle in it. i'm thinking he does this because if he hits the board or is hit in the tightest spot in the track he will be able to turn around, but what i get from what you are saying is that he must be settting his car according to that steering. please clarify

since it looks like you really know what you are talking about i have another question if you don't mind.

1-why is it with the 2 stage wraps double pink&orange in front and double pink in the rear, the front tires are wearing at least 1.5 millimeters more than the rear. this is using:
ride height- 4.5mm fr & rr
camber- 1.5degrees fr & rr
caster- 4degrees fr
toe- .5 fr, 2degrees rr
droop- .5mm fr, 1mm rr (both over ride heght)
the rest of the setup is stock.
this is for foam on carpet using a 19T Checkpoint

It sounds like to me that your car is simply pushing. Generally when a car is pushing it wears the fronts more, and when a car is loose it will wear the rears more. Post the rest of you setup and maybe it is something with that. From what you did post I would say 6deg castor blocks could help.. but id like to see the rest of your setup.

When you steering is set at 16.5d/14.0d is that even with a spool ?
