Wheels for the SL350 R230

Hello, I’m new here and have spent some time searching the forum, unfortunately without success. I drive a SL350 BJ 2004 without ABC, not lowered and no RDK. I love with the rims of Carlsson 1/16 BE in VA 8.5 x 19″ and HA 10 x 19″. Lt. Price list are installed with the 8.5 x 19 16mm distance discs and with the 10 x 19 20mm. All this should be possible without reworking. Now to my questions: 1. I recommend with the vehicle of 19″ regarding comfort and security or for any other reason? 2. What about the factory warranty regarding the distance discs? Have a picture set on which you can see this combination and I find, …….. a real “Hingucker” or??
