RIGHT !
As a whole when lowering cars you need to get the tracking done which is the TOE.
But when fitting coilovers you need to get a whole GEOMETRY, which is the Toe, Camber and ride height sorted. You can drive it perfectly fine now, but it will wear your tyres excessively and will not drive as best it can.
Im not entierly sure on this, but most coilovers you can adjust the camber, but maybe with these V-MAxx you will need camber bolts, best to ring your supplier and ask.
But im sure that with the FK high sports and Konigsports, you can adjust the camber without camber bolts as they already have some sort of camber correction on the coilover strut itself.
Any garage will fit camber bolts, yes. But best of checking with your supplier first, weather you need them or not.
Do not check with the mechanic you used as he seems to think you cannot adjust the rear ride height, which is completly wrong.
