The must have genuine Lexus NX accessory from Japan. A set of go fast 'Lexus Stabilising Aero Fins'.

 

Lmao. Add rice to your family SUV! Buy stupid plastic pieces and stick them to your car! Worth 10hp each!

Please tell me you're kidding....

 

There are already stabilizer fins on most late model Lexus's on the side mirrors and rear taillights. Is this factory or aftermarket? Linky?

 

I thought I' match it up with one of those go fast chip sets from eBay.

 

Google Lexus boutique Japan. Also planning to get me one of those Lexus watches!

 

They (existing ones) are not so much for stabilization (of the vehicle, per se), but more for minimizing wind buffeting.

 

At 60mph, the air around the surface area of the car is still laminar, so as said above, the contours you see on the car are usually to help with noise abatement and for looks, nothing more.

Those stupid things that the OP (not insulting you of course )listed are as useful as the stick on badging you can put on the sides of your car to make it look like the car has vented panels. OR, this is about as useful as someone with an Eclipse putting a 2ft high spoiler to help him with downforce........once he hits approximately 250mph....

The fact that Lexus...or Toyota for that matter put their name on that really sickens me....
