Westfields and axle stands are an interesting mix if you’ve not had such light weight cars on them before.
If just sat there, doing very “light” work on the car they’re not too bad, the issues are kind of two fold though. One, (at the front in particular), if you’re not careful, the two front stands end up very close together, and are unstable if the car is both pushed sideways and in a front to back direction.
And two, the light weight of the car can catch you out. It needs much less sideways force on the car, compared to a big heavy tin top, to push the car enough for stands with narrow bases, compared to their height to start to topple or lift. It’s even possible if working on a particularly stubborn bolt with a breaker bar etc to actually lift one corner of a Westfield off the stand at that side, and again, if unlucky, they can topple.
Thats with stands directly on a solid surface, and directly on the car. As soon as you add extra layers, you can increase or decrease the toppling risk, quite a bit.
At the front, for instance, if I know the wheels will be off, but there is heavier work to do, I’ll put a longer scaffold poll or block of wood under the car, with the ends supported by the axle stands, but the stands a good distance apart - wider than the chassis.
