AU1 Fairmont shock absorbers and wheels

[Aussie Falcon]

Hi,

The Au1.5 Fairmont (oct 99) has done 120k now and looking to potentially change the shocks. I was hoping for better ride than the standard original shocks and a small improvement in handling. What do people recommend?

It currently has the standard 15" rims. I look occasionally on ebay and here for Ford BA to FG 17" rims. If I find the right one I assume the offset is the same in the new models. Going from 15" to 17" with the right profile tyre it won't affect the speedo?

Thanks
