Hi guys I had my front upper and lower arms replaced along with complete track rods and full alignment due to a slight braking and accelerating vibration at 50-60 mph. Now that has gone and the car feels nice and tight but above 80mph I have a very slight steering vibration. I have checked tyre pressures and they are all good and this vibration was not there before having the work carried out.

Does anyone have any ideas??

What tires are you running?

Could be wheels not perfectly balanced, or not perfectly mounted...
As Roseng said it could be tires too...

Take it to a good wheel and tire shop and they would know what to do.

I'm running toyo proxes and the wheels were balanced on the hunter balancing machine, I've retorqued the wheels let's see if that makes a difference...

I agree with all above. Could well be because you've pulled the car back into alignment but still using the existing tyres, the new, correct stance is highlighting tyre deformities/misalignments. A re balance may not help, I had a similar issue once but with Pirelli P Zeros, which I've always found to deform really easily.

Hi guys bit of an update I had the wheels balanced again on the hunter machine, still the same problem. I'm thinking it maybe that the arms I have fitted are not original, they are made in the lemforder factory (twr) and are seen as oem quality but I'm not so sure now....

I don't know if it would be the same for the front, but I got a vibration in the rear that was very difficult to place. At first it felt like a vibration in the whole car. I actually suspected misfiring. As the wear got worse it was easier to pinpoint it to the wheel bearings.
I think that because these cars are so brutal, anything beeing slightly worn can cause vibrations.
The vibration I got was most precent 50-70mph.
