Never checked any of mine before the alignment done,but i had been under it a few times and was happy for it to be done as it was, but did replace front arms on wifes as like the w203 they are crap!
Plenty of 202 C250TD sports running on 16" + 205s from the factory - and 17in AMGs + 225/245 was a factory (or dealer fit?) option (across the range I believe). OK I don't know if the factory option resulting in alignment being tweaked (probably not if done by the dealer). So I'd find it hard to blame it on the fact that the car doesn't have the poverty spec wheels and tyres.The 250TD wasn't built for that setup.
The others may well be right regarding setup, bushes etc, but that car was designed for 15" wheels with 195 tyres.
The 250TD wasn't built for that setup.
Mine is a 240 sport.
I have got the rear sub frame out and I am re placing the sub frame bushes,
then its new tyres and the alignment done.
