Question : I DRIVE a Wira 1.5L sedan and want to swap
to 15-inch rims.
What will the performance be? My stock is 14

Every time I change tyres, the tyre shop will
tell me to install the camber nut.
Is this a must? What's the function? Do car
companies install it as standard?

adjusters, etc, particularly for Protons.
While in some cases there may be a reason for
it in that the front suspension camber cannot be
adjusted any further, the solution is not just putting
in a camber nut or bolts but to find out the Cause

Even if such components are used, you should
make sure that they are manufactured by some
reputable suspension manufacturer and have certification from some test agencies.
Remember that if a suspension component fails,
you could end up in a ditch or even worse.
It is not a question of the manufacturer not
fitting such a component but in most cases, the
manufacturer sees no need to make the camber
As I said earlier, if the camber has gone out of
specification, the cause must be found and the
