The lowest profile roof rack for your 2023 BMW iX is from Thule, though not the AeroBlade Edge (those have been discontinued for a number of years). Instead, what you'll need is the WingBar Edge, which will add 4 inches of height. The correct part numbers for your BMW are the following:
- Thule WingBar Edge Crossbars # TH56FE
- Edge Fixpoint Feet for Thule Edge Crossbars - Fixed Mounting Points # TH29SC
- Fit Kit # TH56KE
- (Optional): Thule One-Key System Lock Cylinders # TH450400 view full answer...
