Who's good with offsets? I need to know what a good offset for 18x11 rears would be?
Welds rts spec sheet says 56mm but seems like that would sit in to far I was thinking 43mm for the rear?
I'm doing 18x10 fronts I think 41mm for those?
Can anyone shed some light on this for me

I'd try contacting Weld wheels directly and find out if they can do a custom offset for the 18 x 11's somewhere between a +45mm up to +50 mm offset. I'd go for a +47mm or +48mm if it's possible. Now if your only choice is either a +43m or +56, then I'd wouldn't go with a 18 x11's. Instead I'd run a 18 x 10.5 with a +50mm offset.
With the front 18 x 10s I'd run the +43mm offset they offer. Another front option is to go with 18 x 10.5's with a +50mm offset up front. Then you can rotate the front & read tires . These are all with the medium hub pad height(low, med, high pad height is what's offered) . Now if you plan on running a BBK with +13" rotors I'd go with the high hub pad height which has a +47mm offset for the 18 x 10.5's and with 18 x 10's it would have to be a custom offset like +43mm; if that's even an available option.
FYI, 295/35/18 tire need at least a 10" wide wheel, and a 315/30/18 tire needs at least a 10.5" wide wheel to be within the recommended wheel widths of most tire manufactures.

Yeah it doesn't make any sense to me either. The +46mm offset should be offered for the 18 x 11s also!
IMO, you might get by with a +43 on the 18 x 11s with the fender lips rolled good and a adj. PHB to center the rear-end up. The problem is that you've got a really narrow range of offsets that'll work with a 315/35/17 or 18 without having clearance issues. That's why I'd steer towards a 10.5" wide wheel over a 11" wide wheel. You'll have better bump stop clearance which in turn give just a little bit of additional clearance that you can always translate into no/very minimal clearancing for 315mm width fitment into the F-body rear wheel wells.

you would think 17 or 18 would be the same as far as that goes. I just bought tt2 17x11 and 17x9.5 the 11 has a 50mm and looks perfect imo. the 9.5 has a 46mm and i think they could be out a little more. so 40mm would prob be just right. I have 275 F and 315 R nittos and the tires look good size wise. just fyi . hope that helped a little.
