Juddering on Full Lock
Discussion

I never thought of this before but what you say makes sense. On the other hand, surely by fiddling the offset of the steering rack, the length of the steering arm on the wheel and the length of the tie rod (so it's a rhombus not a parallelogram
) you can make the inside wheel turn progressively more than the outside wheel. This would mean that it could be right at any speed. 
If the designer got this wrong it would judder on full lock.
On yet another hand (that's both hands now) after reading this thread the noise I always thought was a tyre rubbing on something on the steering has now moved under my seat, so I'm sure it's the LSD!

but the bottom line is none lock 100%.
Some do. My friend has one in is rally car that does, it allows him to carry on through a stage even if he snaps a driveshaft.
Sorry, my mistake, thought we were talking about TVRs here. What I said does not apply to rally cars, off roaders with diff locks or karts.

They all do that sir!!!
My tarmac drive & turning area is on an incline whenever I manouver the car on full lock moving in an uphill direction I get the same grinding noise, I have often jumped out and dived under the car fearing the worst but all I can ever find is a sign of scuffing on the extreme 'outside' edge of the front tyres. I may be wrong but I think the lock is too great for the post '95 low profile tyres fitted.
