A new company recently set-up by ex-Nissan Development engineers just near Silverstone. Check out http://www.elitetech.co.uk
They fitted and aligned my new suspension on my Evo on Friday afternoon, quick and reliable service. Needed them fitted before the Sprint at Abingdon on Saturday and I managed to beat my previous time by 1.5 seconds so can't be bad!
Gareth, who does most of the Spannering is a A1 educated test driver from Nissan and did development of the R34 GTR, so knows his onions! Ian, is a good friend of mine from Uni and is a knowledgable lad with any type of car.
If your in the area I'm sure you wouldn't be dissapointed with their service!
