Would prefer a welded in cage but right now I need bolt-in. Options???

A "Thank You!" to both of you gentlemen.
FWIW: I believe the GMG bar setup comes unfinished/unpainted as well.
FWIW2: The Porsche TQUIP "rollover" bar is different than the TQUIP "harness" bar - harness bar has the additional horizontal bar allowing for harness mounting; the "rollover" does not. Prices are $100-$300 different between the two.

yes .... bolts on shock tower... and front seat belt mounts...
just seams like the spread of the cage works better with das sport seams to help stiffen car up some

The seat belt mount points are on the side of the car. The wall there is single skin: ie, it's not very strong if taking heavy loads, less so in a roll. The cage mounted there will hold in a roll, but overall it simply isn't that strong... although it's clearly proven itself more than strong enough for a seat belt and the more typical loads exerted. Torsional loads on a side mounted single skin panel can result in very small twist/flex through the cage/mount.
A cage that is mounted to the floor: the floor is double skinned to begin with and will be much stronger against vertical loads if the car rolls. And then (I only know of the CS/RS cage for reference here) the cage bolts to a welded plate on top of the double skin. The welded plate effectively acts as a much stronger (thicker) 3rd skin. Torsional loads through the cage onto the welded floor mounted plate has no movement unless the welds break.
Since I had a regular Teq rollcage before (the one mounting to rear seat belt points), I didn't think much about these small differences until my bodyshop showed me the stripped body, where the cages attach, and what the pros/cons were of each cage. In theory it made clear sense, and then I drove my car after the cage change and I was convinced. Now I classify the Teq cage as more of an aesthetic mod that a real performance mod.
Porsche probably realised the performance difference between the cages otherwise they wouldn't have gone to the extent/hassle of developing the floor mounting plates that required additional labour to weld and mount into position.
The DAS cage looks like it has a strong rear section acting as a rear strut brace, but it really needs to mount to the floor to provide the maximum benefit of a roll cage imho.

The Module and Display unit are simply velcro'ed and the little black receiver is magnetized and sticks perfectly to my rollbar (as seen in picture)...I did this so I could easily remove it in 30 seconds and put it in other cars or quick remove for the street...for power I use cigarette lighter adapter...Obviously there are much slicker install guides, ways to hide it and direct link power to it..

And they make a front section kit for it as well, but it is not bolt in. That being said, I think a good welder could make it into a "bolt in cage" by welding some plates to it at the front and making a larger "sleeve" that would connect it to the rear bar. If I was putting in a full cage and trying to keep the interior in tact, I would absolutely go with a Das!!! It is much stronger than any other bolt in system I have seen.
Dell, if you want a further explanation about making the Das Cage a "bolt in", PM me and we can exchange phone numbers to discuss.
