19 inch rims < 10kg for Stinger GT 4WD

Hello together, since I have found no similar thread, I start something new here. I have been the proud owner of a 2019 Stinger GT in black with Bastuck and Panorama roof (just phenomenal the equipment in Kia). Like almost all vehicles, which are in my possession or were, I also play with the Stinger with the idea to lay the vehicle ~40mm deeper and to install beautiful 19 inch rims. So I am looking for 19 inch rims, which according to Mög I found only the Borbet DB8GT2 in 8.5×19 ET35 and the Barracuda Project 2.0 in 8.5×19 ET40. Has someone installed these or other light (likely also lighter) rims on the Stinger + and in particular with which tyre combination? According to the parts report, a 225 tyre is released at the front of the Barracuda. For me, the 225 tyre on a 8.5J rim is simply too narrow. Can one weigh at 8.5J front 245 and rear 2 55 tires? (e.g. part reviews as basis but single acceptance wheel-tire combination)? Look forward to your feedback. Thank you in advance.
