I've got the exact same problem. Had my diff oil changed, bearings changed, been up on the ramp getting checked over and still none the wiser. Apart from now I've picked up a thudding noise when im driving lol
If any spaces come available could i please be pm'd? Don't know how but i missed that we had a stand for this and would love to be part of it if possible.
If there do happen to be any other spaces come up i may also be interested as i think im free from work that weekend now , be my first show in the zed.
I love the cobra resonated boxes, obviously if money wasn't an option there are ones I'd upgrade to but for the money it's good. The only thing that does get to me a bit is the drone at around 3k rpm i think it is. Would dynamat change anything? The only way i found to beat the drone is to stay above 3k
Sorry for the delay, I've changed my mind on size so many times lol. Considered a 30mm for rear but think it'll make the tyre protrude too much at the bottom. So could you put me down for 20/25 please. Even writting this i had to have a quick google of some fitment pics lol.
