My partners car, an 06 Mazda3, has a shudder that you can feel through the floor and body when doing 80 plus kph. It's not a vibration through the steering like you get with an out of balance wheel but a shudder through the body. It has had a wheel alignment recently ( stupidly we didn't mention this shudder to the tyre shop at the time ).
What might the problem be?

Out of balance "Rear" wheel or damaged/buckled rim. But first check all wheel nuts have been tightened properly after recent wheel alignment/rotation.

I'll get the rear wheels balanced next week and see if it fixes it.

Ill check nuts but it was doing it before wheel alignment

could also be an issue with a tyre as ell. perhaps is damaged possibly leaking air under the tread

O.P. Does the shudder change while braking or going around corners?

Not that I've noticed. After driving to Auckland and back today (about 550km) I found that it is far more shuddery on the smooth ashpalt type roads on the motorway than on the rough seal on the highway. Weird huh?

I would check the tyres for bulges. I would check the wheel bearings if the tyres are ok. Another easy check is the brake calipers, the sliders can seize on one or more calipers. Those three things are what I needed to fix on a couple of those cars with the same symptoms on smooth roads.

The 80Kph usually (my opinion) points to the inner CV joint on the long (Right) axle. have come across this on quite a few cars and it's always around the 75-85 kph mark.

Got exactly that on my older Honda Civic. Serious vibration about 80 kph. Right inner CV was shot.

If an inner CV is toast is it worth paying an extra $150 for a complete drive shaft with both CVs on it?

Yes definitely.

Was going to say this exact thing! Inner CV more than likely.

Possibly could also be worn suspension bushes, I had a car a while back that shuddered at 80k due to flogged out control arm mounts.

bjdw-open the bonnet and have a look at the drivers side top engine mount. its sort of teardrop shaped.Look underneath it for a bit of oil dripping. If there is then likely that's the issue.

I was talking to a work mate about it today and he told me his Mazda6 of the same year and with same engine had the same problem and that it was that engine mount so that is the first thing I will look at tomorrow. Cheers.

The same engine mount on my Mazda3 leaked oil but there were no side effects. I did replace it as soon as I noticed it leaking though.

you were lucky --or maybe got to it before it was empty.

Yep, was replaced within a few days of seeing oil on my floor. I hate oil leaks.
