Motion Motorsport Undertray - Questions

If you are talking about the weight of the motion tray. It is heavier than the OEM plastic one. Think i heard 7-8 pounds total.

Yes, the weight difference between the OEM and this tray. Thank you

I'd have to guess around 5-6 lbs. Great for a street car because it protects the ambient temp sensor.

What about the bushings and bracket did you not like?
I just installed my hotchkis the week before we were out at Sonoma Drift together a few weeks back. First track day since i installed this saturday. So will see how it works out.

Their brackets don't come perfectly flat (parts that sit against the chassis). That puts preload into the bracket which in turn pulls on the studs.

I had their bracket come off loose at the track even after doing some tread locker and bent the bracket. I could not get it straightened out, so called them to order a new one for E46 M3. They told me their brackets are universal. Which makes sense why holes are so stretched. Same thing with a new one, was not flat. I got tired of it and used Turner brackets and bushings. I am also not a fan of the nipples for grease and the nasty goo they provided.

I do run their bar, just not anything else.
