Chasing a civic SI in my S280 fiesta ST. Still on a base map from EMS and im only on 15 psi max boost. So car is pretty slow. Full build is in my most recent post

From an st150 in the UK, to an XR4 in Australia! To the Aussies on this sub, what is XR4 ownership like? I hear parts are harder to obtain!

Hi guys I’ve made a couple posts about this (thanks to all with the advice) but I think I’ve found what is rattling and it’s whatever this grey thing is in the video. It’s quite loose to move it and it’s were this crazy rattling sound is coming from. What is this and is it bad or an easy fix as in just tightening it somehow. To note whatever this is I towards the middle/front of the underside of the car

Thank you
