JDM V4 Impreza STi - front anti roll bar

[STi Type R]

Hi,

1997 JDM V4 Impreza STi.

Fron anti roll bar is corroded. It's not standard, gold colour 22mm non adjustable. Thinking of going back to standard OEM, which is 19 or 20mm?

Pros-cons or any thoughts?

Thanks.

20mm standard or you could get yours soda blasted , treated and repainted
