wheel balancing/geometry help

[pullingpower]

I am getting a reproducible vibration at 100mph+ (where conditions allow!). It is difficult to pinpoint where it originates but I think it is due to wheel balancing. Replacing a slightly warped rear alloy helped but did not rid the problem. It is very frustrating!!!
Quickfit etc only balance upto 70mph which is no help. Can anyone recommend a good service who could wheel balance to higher speed and possible check geometry in or around Sheffield. (RT racing don't do balancing)
Thanks

Borrow a good set of wheels, but I dont think that would cure it....

If you have 5 studs, I may be able to help

I had something similar when I got my Chim. I was convinced it was wheel balance and had it done 3 times at different places. Eventually gave it to someone who knew what they are doing (Perry @ the V8 Centre) and he found that it hadnt been properly serviced. The driveshaft UJ was dry as a bone. He opened it up disconnected, cleaned, greased and put back together. Problem solved :-)
