Hi,

My WRX STI 2010 hatch has recently failed the MOT due to creaking from the front. Which he expects it to be the bushes. So just trying to figure out what size/make I need or is the best.

My anti roll bar measures 22.5mm so I would have thought 23mm.

But 21mm seems to be the standard size for my model. So I'm guessing it's had an aftermarket anti roll bar put on?

What do you think/ recommend?

Cheers, Tom
