sadly that's about it
I honestly don't think you bother to read peoples replys otherwise you'd have realised that both me and hash4u have already offerded the smae solution as you.
good idea but it's more important to get the spring load rating correct rather than the length. As for the rim size, that's not right unless you fit larger diameter tyres, which would in turn throw your speedometer off. so 14's are not a solution unless you wish to create more problems.
