I just had some Continental contisportcontact 5 tyres (225/40 r18) fitted on my stock spec b rims.
As there doesn't seem to be a great deal of info on the forum about these tyres I will try to keep updating this as I find out more about them.
I have shockworks coilovers fitted to my wagon.
First impression of the tyres is a massively improved ride over the falken azenis(rears) and kumho ecstasy (fronts) that came with the car when I bought it.
I was forced to replace the tyres after I had some pretty scary understeer in the recent rain we had here in Melbourne.
Fire away if you have any questions.
