I purchased my Mandrus Mlleniums about 15 months ago and have had more ositive comments on then than any other part of the car per se. I put 18x8.5 on the front, and 19x9.5 on the rear. There was absolutely no problem with fit and the TPMS kits tranferred easily. Gorilla nutz were used and I obtained a set of tri star Mercedes inserts from from SRT6nTulsa. Remember these wheels were designed in Germany for the Mercedes so just make sure yopu get 5x112mm bolt pattern.
I bought an SRT6 in May this year and swapped the SRT6 wheels with the Limited Mandrus wheels with no problem. I find them the best looking wheels without being obscene and garish. There are many soft brushes and wipes available for doing the spokes. I use one with a plastic handle and a sponge covered by a polishing cloth.
