Seen these in this month Hot VW Mag.
Anyone familiar with this set up?

Yeah, a link would help. Kind of hard to do inboard brakes with swing arm axles. IRS, sure, but swing arm is a head-scratcher.
Jaguar XKE did it to reduce unsprung weight. It did that but added undue complexity and increased maintenance cost. I've seen the Jag rear used in costly street rods and custom kit cars. I'm not aware of Porsche using in-board brakes - just too much going on in rear with transaxle/engine/etc.
I've heard directly from Sam at Rancho about how the heavier 930 CVs cause premature wear/failure on IRS boxes due to the extra weight carried... wonder what these would do.
The guys at Raxles in Florida told me the same thing when I was looking for new axles. The really beefy 930 axles were too much for T1 Dune Buggy transaxles. I ended up with beefier CVs (I think for a 944 or Van) but not as HD as the 930 version. Been working fine since 2006.
LOTS of Jaguar IRS rears out there in Hot Rods, and they are pretty bullet-proof. O'Brien Truckers has a Jag rear end in their '34 Panel truck with over 250K miles on it and going strong. They use the Panel truck to haul all of their sales booth stuff to shows - over 1000 pounds of cast aluminum stuff. The rear sits on air bags. They also haul a double-sized Mullins trailer behind it.

Couldn't find a link, thus the reason I asked here.
I had just grabbed the Mag (didn't buy it) and was skimming through it while the wife was shopping. Next time I'm at the store I'll try and get more info.
@Bill Prout- Was it the September issue of Hot VW's? I just looked and didn't find it. Was it the focus of an article or just something you noticed in another article?
@chines1- good info- thanks!
@Gordon Nichols- The only time 930 (or even type 4) cv's are really needed is when pushing the suspension past it's design limits (widened/longer arms and more travel), but then usually a bus irs trans is involved. Guys have run type 1 cv's successfully with more than 200 hp on the street and I've heard of someone's street car going 11.40's or 11.60's- on type 1 irs (and it doesn't tear up cv's).

Not sure, I think it had a yellow bug on the cover. It was pictured in Rancho's full page ad and not one of they're tech articles.
The pic is in their ad in the August issue of Hot VW's. I looked at Rancho's website and couldn't find anything; never seen axles like that either. Al
PS- @Bill Prout- I hope you're surviving- what's it like where you are?
Cloudy on Kauai with light sprinkles.
