I need to change the rear 'D' bushes on my 2003 WRX so I have looked at getting upgraded ones, but now I am thinking I might as well get a whole new upgraded rear ARB whilst I am at it...

My question is which size should I go for and would I need to upgrade anything else at the same time?

Thanks in advance.

Go up to 22mm that should give you the right balance for road use and will get rid of the understeer that's setup from the factory,
Whiteline are pretty good but I'd recommend getting it powder coated before fitting as the finish isn't up to our salty roads,

Updated droplinks are always good too.

Thanks for the reply - will look at the droplinks too then!
