Anyone running this?

Beatrush Aluminum Underpanel For RX7 / RX8 | RotaryLove


Considering the complete kit. Looking to improve aero and cooling....

 

I don't think it will really make a difference over a stock undertray. And it's heavier.

Also, LRB Speed makes one here in the states -

FD Under Tray

I saw the LRB unit, but it didn't look nearly as effective / nice. Especially the side panels.

I'm trying to improve cooling and high speed stability on a very powerful street / future road race car.

 

I'd have to agree with Dale...it is doubtful there'd be any measurable improvement in "high speed stability" over the stock unit. Haven't heard of a lot of incidences or lost lap times caused by poor airflow under the car...? The stock unit had a lot of R&D bucks put into it by a major OEM...albeit not intended for racing use, of course.
There are dozens/hundreds of aftermarket products that are pretty to look at and appear functional/logical...but how do you PROVE it makes any difference?


Does look nice, though!
