Rear inside wheel lifting during cornering?

[Zipper]

Racing my durga on Sunday the rear inside wheel kept lifting mid corner, where should I start to try and stop this happening?

[Big G]

harder front springs

[Zipper]

Already have Associated blue springs up front which are one of the hardest available. Not sure where to go next?

[Jamie.T]

Try laying the front shocks down to dial out some grip.

[Northy]

Do you mean inside rear wheel?

[Zipper]

Yep! Doh!

[Big G]

tbh I've had this a few times, but I find the car handles perfectly fine through this 1 corner of the track on 3 wheels that I haven't bothered trying to stop it

You could try moving rear shocks out at the bottom. Or a roll bar.

If the rears shocks were to be moved out, that would decrease rear end grip and thus making the front have even more grip in comparison? if my theory is correct then that would make the problem worse wouldnt it?

Harder front end and softer rear end with a front anti roll bar.... Thats how mine was setup for Petit on Sunday and even on very high grip carpet it never lifted a wheel. I know there's other factors like weight and ride height ect but thats where I'd start.

Like Big G says tho, if its not causing any handling problems then leave it how it is

Only if the front Is diving in but already said has quite hard springs on front.
Moving shocks out reducing rear grip and reducing side bite hopefully helping rear come round more rather than dig in and lift a wheel or grip roll

[Zipper]

Thank you for the replies.... I'll try the above one at a time and will see how I get on.

The problem has proved really annoying, especially on higher traction surfaces, when I grip roll at almost every corner unless I crawl round it at a snails pace.

My first run on carpet on Sunday the car rolled evey coner so I changed the setup to this...

TRF shocks with std pistons and 40wt oil with blue springs up font, 30wt oil and cut down Yellows rear, Outside holes on bottom arms all round and second from outside on the top with anti roll bars front and rear. Low ride height

You could also play with the tyres too. If you're using pins then try cutting the two outside rows off at the front, and even a row from the backs if its still a bit keen.

Its not a perfect setup but it sorted the grip roll and the car was very well planted even over the jumps with good steering. It got me through a very tricky meeting .

[fmo]

what tires do you have mounted?

[Timee80]

Try raising the inner rear ball stud 1mm.

[Timee80]

Try raising the inner rear ball stud 1mm. Or shorten camber link at the hub.

[Big G]

if you have grip roll then that's another matter. Try harder inserts to reduce side bite.

Or just dont worry about it. Mine does it aswell and it dosent affect handling in the slightest. Its just a sign of the car generating good grip, but not too much.
There's not much you can do about it anyway, if the balance is good, changing the setup just for the sake of reducing the inside rear wheel lifting would be considered stupid in my book.

[Zipper]

The problem is that when the rear wheel lifts to a certain point, the car rolls onto it's roof.... it almost happens in slow motion. You can see the car chassis almost twisting as it corners with the inside rear wheel lifting... then it gets to a point where it just rolls over. (I'll get someone to film it next time out!)

Cut every spike off the outer row at the back, still rolls, cut the inner row off, still rolls, cut every other spike from the second outer row off, still rolls, cut all spikes off 2 outer rows and one inner row. Once you have got that far try and smooth out your steering input because if you make it so easy to drive that it never rolls however aggressive your steering input i suspect it will be slow on laptimes.

I ran with three complete rows cut off front and back on high grip astro outdoors last summer. If you read the report from the Petit then you`ll see some of the quick lads were sanding their tyres down so that there were only three rows of miniPINS on the 2WD fronts ! Dont be scared to experiment with cutting spikes off as someone has already mentioned.

i dont pretend to be a setup expert but thats what id be doing before making major alterations to the setup. The tyres always make the biggest difference no matter what the shock positions, oils, pistons etc etc
