Cheers, some good info from that link.snellgrc said:
Does this mean you need to change the wishbone to run with the wider tyres, OR you don't need to change anything at all as this was just because the cars that normally had those tyres fitted also had the extra anti-roll bars/dampers fitted and so that component was slightly different??Its worth remembering that the models featuring 185 width tyres have a different bottom ball joint to models that came with 155 tyres. This is important when replacing the lower wishbone which comes with the balljoint already attached.
So, basically no problems either way.... that's ok then.snellgrc said:you dont need to do anything to run the wider tyres fitted to the GTi/GTa alloys - However - on non GTi/GTa cars there is nothing stopping you fitting the standard size ture onto the rims to make low speed steering easier - you will see what i mean when you do fit them.
The GTi/GTa had a different camber (i think or was it castor?) which was optimised for the 185 width tyres - the wishbone itself is the same - its the joint riveted to the end of the wishbone that is different. This made low speed steering slightly easier
You can retro-fit anti roll bars and dampers to any metro with the right bits - getting hold of the some of the bushes is tricky i have heard as the GTi has been out of production for ten years.
