Impreza STI Aluminuin lower arm on Fr-s/Brz

Anyone experince swaping STI lower arm on Frs? It looks similar, but does it really fi? Would this also save some weight?

They're definitely the right shape, but you'd need to measure them to see if they're an exact drop in or not.

You would have to run them upside down if they happened to fit. The imprezas arms sweep back while the twins sweep forward

Taking a quick look it also looks like the balljoint is on a bigger angle on the FRS arms.

I could not find Sti lower arm for experiment yet. If it fits, LH sti lower arm should be on the right side as you mentioned. The track might also go wider since sti arm is longer than wrx lower arm.

I think the ball joint is going to be the issue here
