a friend of a friend is selling his coilovers ( from his Matrix ) just wondering if it will fit my xA...any Idea ?

I seriously doubt that it would. The only coilovers that *might* work are from an echo/vitz or from an xB/bB. Though I would think that coilover setups are made specifically for each car and the weight that it carries. So while it may be true that an xB/bB coilover setup would directly bolt on, I don't think that it would be 'tuned' for it.

it wont fit

you always want to get parts that are made for your car when dealing with the suspension

thanks guys :)
