I know that ERA recommend the Spax shocks, but it looks like ERA are getting about $1,700 for a set of 4 rear, height adjustable shocks with springs, and that's money I'd rather use in other (not easy to change later on) areas at the moment.

I've had really good luck with Koni shocks in the past. Does anyone have experience and a good part number for height adjustable Koni shocks that work on a Jag e-type IRS? If not Koni shocks, I've heard that QA1 make a good product. Does anyone have any experiance running QA1 shocks on the back of a Cobra with the Jag IRS?

Also, I found these for a series II E-type.

I know they will likely not be as nice as a set of Koni shocks that I'm used to, but they should get me on the road, and again, running a track day with these shocks would be more fun than sitting in the driver seat of the car in my garage making engine sounds and pretending I'm driving while shifting through the gears. Does anyone have any experience with them? They should fit, right?

Over all, once I wear the budget shocks out the car will end up with the most premium shocks that I can afford, but for now the primary concern is putting the money where it is needed to get driving asap and at the moment $1,700 for rear shocks would take too much away from more permanent areas of the build.
If you haven't already done so you may wish to check out this old CC thread: JAG IRS Shock Options

QA1 lists spring rates for Jag IRS with their coil-over shocks, so they likely have some experience with this. I've had excellent service in dealing with their technical support folks and would recommend reaching out to them if you're thinking you may go with QA1.
