Help needed:Front wish bone

Hi there. I drive AG 2009 RS 200 cup.

I have movement in right wishbone rear bush.....feels like it over turns when making left turns,really odd feeling.

My questions are:

Can i get aftermarket wishbone like these one and will be ok with the rest of the CUP stuff?

Should i get left side as well?

What else would you recommend for me to get for suspension as i am not from UK and it gets a bit cheaper if i order bulk packs:smile:

Thanks for your help
 
no need to get a whole new unit, the bushes are exchangeable, no need to do both sides if the other one is ok, also no difference between cup and non cup.
