Need input - Custom Rear Strut Bar Design/One Piece welded-in/G35 COUPE

[Z&G's Parts Dis]

>>>>>NEED INPUT IN REGARDS TO STRUCTURAL DESIGN<<<<<

I've been on the wall with whether i should buy a rear strut bar, or just have one made. The main things that i feel are problems on the current rear strut bars that are out are: lateral offset to the rear strut mount, lateral flex joints, and something else that i cant think of at the moment.

So im thinking about having a one piece rear strut bar made out of roll cage tubing, either having it just welded in or having plates welded in on the tubing ends which have holes for bolts which i can then use bolts to hold in place. Of course if i opt for it to just be welded in, Ill have steel plates welded on the ends for structural support and to help spread the tension load during hard turns.

here's some example pix of what im thinking about getting made

>>>>>WHAT DO YOU GUYS THINK<<<<<
KEEP IN MIND ITS ACTUALLY CHEAPER ON MY END TO GET THIS MADE
AND I GOT A G35 COUPE

The picture of the trunk without the trim pieces illustrates actual placement of tubing ends. The picture with the trunk with the trim pieces in may be a little off vertically. These are just example pix

Here are the 2 options for the ends:
With bolts [not welded in]


Without bolts [welded in]

Id love to produce this thing for profit. But due to the variances from car to car [of the exact same model] i cannot produce a one piece that can fit every car. If its a one piece, it has to be custom to each car
