Interesting, I towed my glider up to 80mph with my subaru forester 4cyl, in fairly strong winds.



Sounds like the axle may need to be moved on the trailer.

I have a 2011 Outback with the 4 cyl engine towing a 2001 Cobra Trailer with a Hph 304 CZ inside. It tows fine up to 60 mph. After that it becomes unstable with violent side to side excursions. So I just tow at 55 mph. Interestingly, the trailer did the same thing while being towed by a 1994 Subaru Legacy and a 2004 Subaru Forester. I tried adding weight to the front end of the trailer to no avail.

Yeah, that sounds like something more than "just" a tow vehicle problem. I use my 2010 VW Sportwagen TDI (front-wheel drive only with helper airbags for the rear coil springs) and it tows an LS8 in a modern Anschau/Komet trailer fine up to 65mph. It's lighter, slightly smaller, and less stiffly sprung than the Outback.
