CL9 lowered, Fitment/ Petrol tank knocking/clueless

[melbeuro]

Got my racing logic coilovers put in the other day love them to death, so I decided to slam the car, and attempt to tuck my old enkei wheels (rears are 17x9 +38). This went well as you can see in the photos. But my issue started today when I went for a fill up. I was driving out of the petrol station and I hear knocking, not to loud, but enough to hear. constant knocking over 15-20kph no idea what is going on, I have a strong feeling (correct me if Im wrong) that if the fuel tank sensor actually floats, *yeah I don't know how this works*, then it might be hitting the top of my fuel tank as I have a bad habit of filling up a few click more than Max. My fuel gauge at the moment is over the maximum line but about another line if that makes any sense. I have checked for knocks and scrubbing from the wheel to the bottom of the shock yesterday before the knocking happened because I had a weird feeling it may have been rubbing and it was, so the rear is not as negative anymore, I adjusted it enough. Nonetheless I have plenty of clearance between the shock and the inside of the wheel.

As I stated before the knocking only seemed to become apparent when I filled up a full tank today.

Cheers lads lemme know your thoughts.

Doubt it is your fuel level sensor. I reckon it is the weight of the fuel just getting your car that much lower that the negative camber is causing your rear wheels to rub against the suspension. What are you rim size, offset and tyre size?

Thats what I thought. But I stuck my head down under the car when it was sitting and it looked fine, perfect clearance, in fact plenty. the rear spring rate is 5kg and to of 32 dampening it is on 16. my rear wheels are 17x9 +38, 255/40/r17
