M car has just had two new front tyres fitted, the old 1`s were worn heavily on the inside which is nothing uncomman for an mk3 lowered, in particular the drivers front one more so, i had the tracking done on 4 wheel computer and its showed thet the os front wheel has more negative camber is there any way of adjusting the camber so i can get them equal???
the car is lowered 60mm on konis with speedlines 17 x 7.5 with 215 /40 /17 tyres et 49
i have also notice that the car pulls to the left slightly when coasting as well as accelerating could this be causing that problem. (drivers camber)
The cars also had new bottom arms, springs, track rod ends anti roll bar links and more recently top mount bearings which were fitted by a m8 is there a special position for the top mount its self because i feel the proble has come since they were fitted a mont since???
Well mate i don't know anything about camber but i had a similar problem with my passenger side tyre. When i went to get the tracking checked it was spot on.
I too thought it was the camber that was out. Subsequently i was also told that you can't adjust the camber on the front of Mk3 Astra. How true this is i don't know.
They also told me that the only way possible was to get the front end jigged.
I find this hard to believe but that is what i was told.
Anyway i manage to solve my problem. It was a directional tyre going the wrong way. Was a spare so wasn't too bothered.
If your running 17s there will allways be a problem. Have your alloys got the correct offset of et40?
If your tyres are wearing unevenly this will undoubtedly cause your car to handle differently because there isnt an even distribution of weight on the running surface of the tyre. I think many people will say its normal and nothing to worry about, but i would not be happy at getting abnormal wear after spending loads on fancy wheels and tyres.
Bottom line is,
lowered car and different wheels= altered suspension geometry
Camber can be adjusted to a degree by using adjustable topcups that allow the top of your suspension assembly to be moved within half an inch of the normal position but this will cost 180 pounds for the parts and you will need to get decent alignment tools to set it up properly, Think lazer line tracking systems can do it.
another thing worth checking is that the topcup assembly is correctly aligned, The rubber mount that sits ontop of the spring can be misaligned and would effectivly raise the car by as much as 1cm enough to make a difference
Jigging the car is another option but this process is normally ONLY used if the car was bent in a crash.
