question about a 2009 Porsche Cayenne roof rack system

[DUTCH VanAtlanta]

I have a 2009 Porsche Cayenne with existing factory roof tracks. I want to put a Thule Boxter 611 up there. The original plan was to use the Thule 430R, RB43 and TK1 base rack system under the Boxter 611. However, a retailer who sells both brands recommended using the Yakima Control Towers instead, since they provide a tighter fit to the factory roof tracks.

I prefer the looks of the Thule base rack system, but want the strongest setup possible for use off road. Looking for a second opinion. Any thoughts? TIA!

No reason not to use the Thule TK1 Tracker Kit to assemble a 2009 Porsche Cayenne roof rack. It's a good fit and no worries, and you get the really premium look of the Thule 430R Rapid Tracker system which will look awesome on the Porsche Cayenne for sure.
