Snap oversteer

[Jersey Tom]

I Founf a problem some time ago were the shop top is bottoming on the bell crank causing the shock to bend and wearing the shock top out bad. Would this have any effect on the reaction of the rear of the car.

Uhhhhhhh.... yes.

The shock is hitting on bump . The problem is the cars are running much higher here than they ran in Germany wich is causing the rocker angle to be out resulting in the hitting. I tried to file the shock post but it is still hitting it really hard. Now would that not act as a bump stop causing that snap ?

Bottoming suspension violently = bad things.

Can't you run some stiffer springs?

snap oversteer is refering to a situation where the car is going from a understeer/neutral situation into a sudden oversteer situation at corner exit.
very often ,this is a tyre temp issue.

I find this questionable.

tyre temp is an effect, not a cause
of course, as any effect, it causes other issues down the river

Alonso, dont run high wing, aero wont compensate you rmechanical problems.
Measure temps, its easy and wont be in vane. Info is never in vane.

1)Reaching the bump stops suddenly makes your spring rate infinite.

2)You never told us what fatburner asked you...

3)I guess your driver is pushing the accel gently in corner entry...

Its difficult to tell at first sight, as I dont know the car, but I guess spring rates and geometry may be all wrong. Do not pay 100% attention at the rear, as both ends are always be related...

The remedies i have tried have been the following.
1 Roll bar adjustment from full soft to full hard
2 Shock adjustment bump from hard to soft Rebound from hard to soft
3 Camber on the rear more negative from 3,2 to 3,5
4 Rear wing more and less (but as i said it not aero its machanical)
5 The only thing that did make a diffrence but only a little was pre load. (that car is so hard in front with preload its crazy) but preload should only take anetial turn in away.
6 Tyre pressures tried harder and softer.

These are the remedies i have tried but the team i work for are a bunch of ..... and i have told them many times that the shocks hitting the rockers is the problem. Its acting as a bump stop causing the snap. Because so many changes to a race car and no diffrence its crazy. This is a single seater not a truck come on the smallest change in the car is felt straight away. I know with my driving experiance that if you make that many changes and no diffrence, its something broken or serious thats causing the trouble.

Would to much droop cause the snap? i took it from 13 to 23 and it made no difrrence so it cant be that?

I still think as you've pointed out, the bellcrank/shock interference is your main issue, since it'll manifest itself in both ride/bump/squat mode as well as roll as it effectively will limit your bump travel. Maybe as Jersey Tom said trying heavier spring rate(or add packers) so that you bottomout on spring material as opposed to on the shock, which hopefully is less of a rate difference. Fundementally though I'd think you have to fix the clearance issue. Unless thats a homologated part and you can't modify it in any way....
