Nope, not big enough spokes for an SUV. Everyone has their own tastes though. From HRE the only wheels id put on an Escalade are the 940RL series. 943 and 948 are my favorites. I almost pulled the trigger, but it was going to be $12000 for a pair of 4 configured the way I wanted them, and that was before tires. Maybe the p and s series wheels are cheaper. If you like split spokes, id look at the Gianelle Bologna wheel. I ran those last summer.
This time I went with a different wheel that looks quite similar to the 943RL but significantly cheaper. The Gianelle Santo 2SS. I'll post pics once I get them installed.
HRE vs Gianelle
as for brakes, I would look at Baer. A lot cheaper. I confirmed with them they do have a kit available that works on 15s.

Bologna's come in a bunch of different color ways. For a white truck Id get them in silver machined or chrome. Here is the silver:
The most commonly used color way I see on 15s is the black machined. I have a set laying around if anyone's interested. 24" with about 3000 miles on them.
