I'm trying to locate an after market aluminum wheel that I can mount my 275/40/20 drag radials on. They have to be the 20" size to clear the calipers. Any idea what I can use? Can a 18 or 19 inch wheel fit? Just interested in the back only, for drag racing use.

Anything out there for a 2008+ should fit the 2011 as well. There are tons of threads on it if you do a quick search. People go as low as 17.

I don't think so. They need to be large due to the huge caliper of the Brembo's

The same brembos on the 2011 srt have been used on the 08-10 srt. You won't have a problem using anything currently used on an srt.

Yeah buy some Weld 17x10s. That's what I plan to do after installing the Brembos on my R/T

I've checked numerous dealers and manufacturers and they all agree. Due to the oversize Brembo brake caliper on the 2011 SRT-8, only 20 inch wheels will fit. These calipers are larger than anything that is on previous Challengers. There is about an inch clearance between the 20 inch wheel inside area and the caliper. But I'm still checking. I decided to go with the Nitto NT 555R 275/40/20 on a Centerline forged wheel.

I don't think the brakes have changed since the previous SRT8s. It might not look like a 17" rim will fit, but they will.

The Brembos on my 2011 SRT8 are the same exact "model" that came on my '06 Charger SRT8 and '09 Challenger SRT8. So, any wheel that fit those cars will fit this car.

If you have 275/40/20 drag radials they will only fit a 20" rim. A 17" rim may clear the calipers but won't be able to fit 20" tires.

Why not use a stock SRT rim? It's what I did.
