i have had two mr2 roadsters and both of them used to drag the front wheels slightly when reversing with full lock
is this normal the dealer said it is
Well it certainly seems to happen to a lot of us... whether "normal" and "acceptable" are the same thing I'm unsure.
I'd have a read of this:

There are quite a few other threads in this forum about "clonking".
sounds like there is quite few having this happen on there 2
so it sounds like the dealer was right for once
