I swung by Agent 47 the other day to pick up a new mirror for my car and Heath had just finished installing their new Strut Tower Brace for the S197s that fits the factory plenum cover on the 07s+.

BTW If anyone is in the San Diego area (or near and doesnt mind the drive) A47 is still looking for a car with a stock hood and a Whipple, Kenne Bell or FMS Supercharger to test fit this new brace and they will let you go home with one if you let them use your car for a few minutes to do the test fitting. Give them a call and ask for either Corey or Heath, (760) 496-3809
Here are some pics of it on a friends car:
