bolts right on to the stock rack locations, NO DRILLING REQUIRED.
The rubber pads under the stock rack are reused with the calmini
rack. You just need to trim off the middle top portion of
the pads to make them flat.
You will also notice the base of the rack does have the bases
bent to match to roof line. The
rack comes in 3 pieces for shipping and this also helps with
installation. There are sleeves you stick into the rack that
need to be drilled out and using the self tap screws to secure.
I would attach the sleeved to the front and rear portion then
attach those to the main rack. You only have the rack loosely
assembled until it is fully bolted onto the roof, this makes
it easier just incase the stock holes are a little off/different.
attachments DO work with the rack.
the amount of space and shear strength is insane. I can litterally
jump on this and not deform the rack and of course the roof
is fine as well.
