What are you guys using for drag wheels

I think the minimum diameter is going to be 18" based on your rear calipers. My dust shields actually rub my wheels if I don't bend them in a little. As for wheels, I can get you the offsets in the morning.
Here's the actual split spoke rep I'm running. Tires are MT ET Streets 265/40-18.

That would be great. Sorry about running quicker, but I've been racing cars for a while and seem to have a knack for it. As crazy as it sounds, I'm disapppointed with the results, as the car had a 11.4 in it that night, and I screwed up.

Well it was at a crappy track and every pass the traction control would kick in at some point. So the best I ran was 11.7. Track is also at 1200 ft elevation I think.

I will be running wheels that match what is on my car in the sig pic below. They are Niche Essen wheels and come in 18", 19", 20", & 21's. One of the reasons I picked them was so I could run my DR's any time and have matching wheels.

I'm fortunate to have a nice track with great prep. Also, the 500' DA helped as well. Have you tried running in Dyno Mode??

Here are the wheel specs of my setup: 18x9.5 et 45mm
Tires are MT ET Streets, 265/40-18
Without spacers the wheels clear the calipers by approximately 1/8".

The prior owner of my 05 CL65 put on 20 inch AMGs. I do not know what model or year they were from or why that original owner did so. The rear tires do not clear the fenders even with the fender lips rolled. When I bought it new Michelins had just been put on it. I'm not going to scrap them and pay $6-8K for new rims and tires at this time anyway.
The result is I have to have the suspension set on high unless I know I won't be hitting bumps and RR crossings. On low they will hit on bumps. I hoped slight kicking out the rear wheel openings and rolling the lips would cure it - but didn't. It did add some clearance in a way, but a mixed bag. Before, if it hit the top of the fender it just rubbed along the fender lip. Now there is a tad more clearance, because it rubs the rolled lips against the upper sidewall - which could do some real tire damage. Frustrating as I only need maybe 1 to 2 more millimeters to clear.
So, as I write this, Renntech is putting in the module to allow adjusting the height at all wheels in 1mm increments for which hopefully I can find an acceptable middle setting for stance height.
It is very common to see rims - new and used - advertised as fitting all CLs - CL500, 600, 63 and 65. But the 65 has 60mm offset - making finding rims that correctly fit a real challenge. .This is a beware notice for folks looking for rims. Rims for other CLs do not correctly fit 05-06 CL65s.
The other catch, of course, is the big front calipers if you want to go smaller than the OEM 19 inchers up front.

In my opinion, it would make more sense to spend the $$ for the differential to get 100% equal traction on both rear tires (cost about $5-6K) than try to figure how to get more traction by better tires, when too much power is lost to one of the two rear tires.
I've always been puzzled why manufacturers tend to put crappy differentials and even what is essentially 1 wheel drive in otherwise excellent cars. American car makers have always done that. The earlier Jag XKRs came with 1 wheel drive, while they put the good until in their Aston Martin. The reason appeared to be the help justify the dramatically higher price of the Aston Martin, though otherwise the two identical in performance, interior layout, weight and basic profile.
Of course the manufacturers don't put on the stick: "PS, this car has a crappy differential that is virtually 1 wheel drive so you should immediately give the dealer another $6K to put in the correct differential unit so you can actually use the horsepower of this vehicle."

Yeah I just think it would be mostly miss. When I go to a better track I will try that but where we went there was maybe 25 cars running so there wad no track prep at all. I may go this week though with my new diff now.
