It depends on how low you want to go.
If you dont go silly shouldnt be a problem.
My mates old m5 E34 was dropped by 40mm on SCHNITZER 18" running 245/40/18. thats 8.5 J X 18" i will ask him nextime i see him if he did any arch work but i dont think he did.
He did you a full suspension kit though not just springs.
drifting drifting and yet more skidding
