6mm offset front and back, 9mm offset front and back, 6in front 9in back?
I'm assuming issue has been tested and handled already by numerous folks running 190mm electric touring car chassis.
Measure your track from hub to hub. Just because it says its 190 doesnt guarantee that it is. It might be 188 or 192 or there may be even more discrepancy. On 200mm shells I like to use 3mm offset in the front and 6 in the back. On a Vintage shell that is 200mm in the front and 210mm in the back I will go 6f 9r offset. There are also axle spacers and things that can help you tune closer to the overhang of the fender.
Understand that zero offset rims on a true 190mm car should measure 190mm rim to rim. A 190mm chassis with 6mm offset front and 9mm offset rear should measure 202mm in the front and 208mm in the rear. You can see how that will sit better under a shell that is 200mm F and 210mm R.
On a 200mm shell I would try offset 3 Front and 6 rear.
