What negative camber do you guys run on lowered cars

[Northy 8]

I have put the camber bolts in the frt struts
Set to -2 camber and when pushing on left bends you get a rumble from the n/side frt wheel
I am guessing bit be the drive shaft hitting in the diff
I have been told -2 deg is ok on lowered cars like mine on cooksport springs
Only other mod is 20mm spacers
Any ofyou guys running -2 or more on there lowered car with any issues
Thanks

Only rumble I got was from the bearings needing doing. Fine since with -1.83 camber. Going for -3.2 next week. That's on Cooksports

Its an odd 1 for sure,,

I can't get them lower than -2.2 camber on the frts
Something is odd as you are meant to be able to run positive camber if required
Any ideas please
