Context and General Issues:
Given the original crossbars are not available due to a number of us over torquing, rust without covers, cracking glass roofs, etc., I figure a few of us still got our hands on them. There is also a tendency to crumple the paint on the front and rear mounts interior mount side (pointed towards the middle of the car).
Lucid is reviewing other potential vendors and install design. Hopefully, they come out with something better in the future.
My Personal Experience:
Anyways, the crossbars are time consuming and difficult to mount. Alignment and juggling screws will leave you frustrated during mounting, particularly in hot Alabama weather. The foam edges are insufficient and leave hard contact points to damage and crinkle paint. I will likely uninstall and attempt to buffer the paint despite Lucid Service suggesting to just leave them on permanently.
That checks two issues for me: over torqued screw (on a loaner) and damaged paint (Lucid Service install on personal vehicle)...
The bike mounts offered are straightforward, but the height can be difficult if not mounted near the side of the car. These are not properly designed for the Lucid crossbars with the curve not aligning with the front mounts of the bike racks. Tightening the front pulls the leading edge of the crossbar mount that then causes the damaged paint issue...
I suggest either a foot stool or partner to help.
Efficiency, Handling, and Noise (Crossbar Only):
No more wind noise than the usual. Handling is not affected in any noticeable way. Efficiency does not appear to change either, but I have not done rigorous testing.
Efficiency, Handling, and Noise (Crossbar Only):
I will find out tomorrow. Expect to not whip the car and take it gentle to start. No real plans to really push the car with two mountain bikes on top.
Verdict:
Would I buy the mounts if still available or used?
Yes, but I would make Lucid Service do it due to the difficulty and other landmines. The silver trim is apparently a plastic and metal mix, so no rust issues occur due to a crinkle, only cosmetic. Replacement is supposedly not expensive either if you ever decide you don't want the crossbars on the car.
If I ever had to install the crossbars myself, it would be a solid pass.
