New Jimny product manufacturer (with our own Jimny)

As I understand it, earlier jimny's have had a 30kg limit regardless of roof bar manufacturer. For the gen4, only the suzuki bars have that limit. check roofbox.com for old and new roof bars, the ones for the older models all have 30kg limit, the new ones don't.

I'm relying on it, I have a 42kg kayak to go up there (but not on windy days).

i think it's maybe a stability issue due to a raised centre of gravity, rather than a structural limitation ?

This is exactly my deal, a tent. I need a car that can handle it.

If they are checking back on this thread, maybe Paranoid can come up with an answer?

My guess is the dealers won't know much as yet, and Suzuki UK has got other priorities. Suzuki Japan could probably tell us - but almost certainly won't answer directly?

Sadly a Jimny probably isn't a good option. The max roof load specified by a manufacturer isn't the maximum physical weight the car can support before being squished, it's the amount of weight it can transport high up without ruining how the car handles, which is why I doubt the max roof load has changed from Gen3 to Gen4.

Stick 100kg on the roof of a small, narrow car like the Jimny and it might be fine when stationary, but moving the centre of gravity upwards significantly will probably make it hazardous to drive and increase the chance of rollover.

You can probably get away with it, right up to the point that there's an accident and your insurance refuses to pay out.

That's why I'm not investing in a roof rack, but going to get a cheap (and light!) set of roofbars instead.

I'm inclined to agree with Gadget.
Roof bars are a lot lighter. The beauty of a rain gutter means you can have them as far, or near apart as you like. You could even get two sets and still save on weight and cash.
FYI Thule square bars weight 4kg each including the mounting feet.
