As mentioned id get it to full weight and sit it down, and your springs will settle a bit.

Id do all that and although your not going to be to the likes of many you may be ok.

Im a bit the other way with a full cell and if im running two bottles on my street racer, but if I run only 5 gallons im about 85% back and have never had an issue.

I set my whole car up with still using the oem shackles so I positioned the sliders eye where the shackle eye would of been and had to make no other alterations
