I concur with Hotsauce -Wilwoods are not appropriate for any kind of daily driving.

I spent a good amount of time inspecting a Wilwood/Perrin kit for use on the old WRX, and I'm glad that I saved the money by not buying.

I realize that your Ax is far from an offroader, but you had better like rebuilding your calipers 2x a year before you consider the Wilwoods.

I've used StopTech's brakes on two other vehicles, and Nissan/Sumitomo on another two. For fixed-caliper brakes, it's tough to beat the StopTech units.

If you want bling brakes, without switching from the floating caliper design, consider the Baer calipers. They look massive, and come in a number of GM friendly (not too far from our discs in size) fitments. Look up the Eradispeed kits for BBK options.
Floating calipers also have fewer problems with spoke clearance for them fancy wheels you got.
