Also, is the rear end only unstable once you start cornering? Or does it start when under braking?

it just seems to be off power cornering.
I was thinking of possibly going slightly harder on the front oil and see what happens.
think i'm still on 5 & 4 on the droop and i just use the schumacher blocks to measure it.

Good Day!
I have had my Mi4 for about 2 weeks now. Two weeks ago the car was pretty good (missed TQ by 1 second).
This past weekend, the car would flip right off the track under any hard or fast corners. I haven't changed anything between races.
The car flips off the track both directions.
I have tried:
New tires
Gluing the sidewall of the front tires
Less camber (front and rear)
more camber (front and rear)
more rear toe
less rear toe
toe out in the front
toe in in the front
Harder springs in the front
softer springs in the rear
harder springs in the rear
Angling the shocks in and out on the shock tower (front and rear alternately and together)
If I drive it at 80 to 90%, it goes around the track quite well. It is fasst and doesn't have any strange tendencies (maybe it is slightly loose)
Anybody have any ideas?
What is recomended for spring rate and shock oil?
Thanks,
Rob

Try going from the kit 3mm spacers to 4mm spacers on the akermann
Will turm better for less steering lock
which could be your problem? front wheels hooking in corners off power then that sudden turning of the car on power?
(is a tip I got from Ben Cane, worked for me and Cairns)

Rob,
Sometimes at larger events with more traction I find that the car want to do that when turning into hairpins and sweeping corners. I don't think there's really a setup change that will help the car in the area that won't affect the car in the other parts of the track.
Usually, for me, I find just making sure i go into the problem corners a little smoother than usual (be more progressive with the steering, and roll on the throttle rather than blipping it), the car does really well around the whole track.
Are you running on carpet? If you are I could send you a setup base from my most recent event.

For high-very high grip i need to run 5 & 5 droop to keep turn in and out balanced. Make sure you don't have any form of drag brake on the speedo. I also remove the rear roll bar if its a very tight track and i need to use lots of steering lock..

Yes, they seem good, as posted by myself and Chris a couple of pages back. I've run both steel (kit) and alloy versions.
