I've just had my Tracking done on my S3 turbo post new front suspension. When I took it to my local garage(which has the 4 wheel laser alighment set up) they were ready to go, except the toe in settings they had were for an 88 stevens. Their system did not have for any Lotus prior to 88. Just as well I'd brought my trusted Service Manual, as there is quite a difference between their S car readings & my service manual. I did find this odd as my car has later suspension & brake set up which I beleave is the same as the early S cars
But he set it up as per my book with no problems. I will be keeping a close eye on tyer wear just the same & she's settled a bit lower than was when was done. I was also please to find out that my rear was barely a mil out.
With the right kit it look fairly straight forward, he even showed me how it was done, which boosted my confidence a bit.
My recomendation, well apparently you can do at home with a drive over pad & measure ect, however I think for acuracy or as close to, then find a good garage with the right kit. Cost me about 20 odd quid so worth it to save on the hassel.
