Bump stop length for drop springs.

[Smokey159]

I guess he's screwed haha, that and it probably explains the noise we hear when he hits a hard bump or cuts a hard turn.

I'd say the noise he is hearing is tire rub due to oversized aftermarket wheels with say a 40mm offset maybe?

Not cutting the bumpstops enough only restricts the travel of the suspension, which would actually keep the chassis away from the tire. So the fact that the bump stop was only cut in half is a good thing for your buddy because otherwise the rub would be worse.
