Will these work 19x8.5 all around, 5x114.3 and the offset is 37 ???

it should fit fine, but you probably want to make sure there is caliper clearance.

I think the stock offsets are 18x8 ET45 and 18x8.5 ET50. I found an offset calculator that will tell you the change in inner clearence and outer position based on the old and new wheel width and offsets. Offset calculator Any of you wheel experts please tell me if this thing does not calculate correctly...

So will they work ?

Did you take the time to click on the link I posted?
If you enter the numbers it shows the following:

Front - 8.5in +37 gives you 2mm more inner clearance and extends 14mm more on the outside than stock.

Rear - 8.5in +37 gives you 13mm more inner clearance and extends 13mm more on the outside than stock.

So, if this thing is correct, yes they will fit. But, I am no expert, so you need to confirm this for yourself...
