I have Toms 40mm Rear brake caliper upgrade too, I do lots of charity joy rides / Track days and that rear brake caliper works just fine
One thing that would look better though is for you to get some rear caliper covers like this
These cover plates screw onto the holes in the brake pad so they float back and forth when pressure is applied.
I noticed now that the Viper Store has some new chrome bling caliper covers that attach to the caliper itself, I would not recommend those as the heat in the caliper body would not be allowed to disperse, which may boil your fluid and cause lack of braking!
