camber
Hi,
Can somebody tell me how much camber I must have at bump and at rebound?
Also which travel up and down is normal for a "seven"?
Is there any logic explanation.
At front 1 inch bump result in -0.20 deg. At rear 1 inch bump -0.90 degr.
Is this good or bad?

it is required to compensate for body roll in corners, as the car rolls over, the wheel keeps verticalish. Id start with a bit of static camber and
see what happens in roll. 0.2 of a degree doesnt sound much though.
by the way, there is no 'must have', its all down to personal preference etc, and trial and error. People on here can only offer advice in
relation to their experience or research, i'll point out now i dont have much

Camber
Hi
Don't know if this helps, but Luego recommend 1 degreee static camber for front and rear in their build manual.

Different camber required between bump and roll with any normal IRS you can can't get both right.
Only suspensions systems that get both right are live axle and De Dion.
With double wishbone irs camber change on roll is usually about than 1/2 the angle of roll.
In addition on a Locost it is normal to run some static negative camber - how much depends on what the car is used for.
Most Locost double wishbone systems just copy the front geometry but move the wishbone inner pivots to give higher rc at the rear -- the rear
ground clearance under the chassis is also usually higher than the front.
