Yeti has a 127 bar and smax 135. Will there be enough space to fit the footpack instead of me buying the whole thing – thule aero bars

Assuming I’ve understood you correctly (length of the bars themselves?), I did the same on my Whispbars when I went from a passat to a zafira.  The bars are in theory slightly too narrow for the Zafira but they work just fine, I just had to change the feet.

how much overhang have you got? you’ll have 4cm less each side.

Fire off an email to roofbox.co.uk – they’re really knowledgeable, very well priced and their customer service is superb.

Came to say the same thing as Cougar

I had 120 Thule aerobars on my SMAx for three years and they were at the limit .( just measured them on my current car

Your  127’s should be fine

What mount do you have on the Smax roof?

I’ve a full set of mounts from the solid rails that will fit. Thule. £20?

Edit: these.

It’s the inset mounting points matt, cheers though
