I am static on bc's...the rears are completely maxxed out including perches all the way down, fronts are all the way down, not touching preload...still need to decide if I am going to cut shocktower or not...it just bangs a lot right now.

this is all the info on the offset i am able to share for our ls430's:

without rolling fenders lowered on coilovers i guess around +25 with a stretched tire (like a 245x30x20 or 255x30x20). with rolled rear fenders then around +20 with shaved rear fenders around +15 all with the same size rear tires and on a 10" wide rear rim. give or take a few mm but i know i can't be that far off. with a mild pull of the rear fender around 10mm and the longer than stock rear arms adding more negative camber you could run a 0 or -5mm if you were on a 245x30x20 on a 20x10" rear rim. all these specs would be very flush with the tire up agains the fender all close like

please let me know if anyone else has a different opinion or real world knowledge...

*****my closest comparison would be right now i am sitting at a +20 offset (super flush in the rear) on a 20x10 255x30x20 with 5mm shorter rear arms and a shaved rear fender. so if i ran the 5mm longer than stock rear arm that would be a difference of 10mm right there so a +10 offset, and with a fender pull of around 10mm i could run a 0 offset at that point on a 255x30x20 20x10", so on a 245x30x20 you could run what a -5 or such negative offset. if you wanted to pull the fenders more than you could run more negative. good luck*****
