Nice work, i love it! I'd deffinitly be down for one depending on if and when the GB happens.
One thing that might be worth considering with any possible design changes is in the rear mounts, implementing a way to use the stock bolts, springs and E-clips locked into the brace just as they are on the Targa itself. the parts are cheap new from Toyota and therefor no loose bolts to loose or anything. Its a fairly simple tubular structure, or even better peices can be bought form toyota also and can be bolted or welded to the brace.
