Gs300 Steering Rack Damper

[summerst]

I recently bought a GS300 - but didn't notice at the time of buying that at high speed the car suffered from bump steer. This turned out to be caused by the steering rack having the wrong mounting bracket on the passenger side. Does anyone know of the correct part or have one? It's wierd because the bracket looks right and fits right - it's just mounts the rack 20mm low on the passenger side - I've corrected it by putting a spacer between the bracket and mounting lug - but I really need to get the right bracket.

Also, the car seems to suffer from exessive tyre noise - is this normal for a GS300 or do I just have noisy tyres - BARUM on the front and Continental ECO something on the rear? It gets quite intrusion around 100mph - which I see quite often as I live in germany and go to work along a stretch of unrestricted autobahn! Had it upto 130 the other day but chickened out then - although the car was up for 150 I'm not sure about those tyres!

Any advise gratefully received

cheers
