I didn't weigh it, I couldn't use the undertray piece with my Q300 catback and I got the FRP not the CF version. All that said I believe it's weight was pretty negligible.

 

Cool, thanks.

 

Snapped a quick side-view pic before my hike today, as promised:

 

^nice! What wheels are those? What specs are they and what tire size are you running?

 

That does look good, I’m digging it more than I expected to.

 

Yeah it sure does! That is a stylish, well designed diffuser for sure. The spoiler is cool too but I'm really feeling the diffuser.

 

It's a newer brand I found which is commonly used on Vette & Mustang forums https://www.signaturewheel.com/

These are the SV901's, forged monoblock in matte black. Spec's are as follows:

Front 18x8 35mm offset (225/40/18)

Rear 18x9.5 40mm offset (265/35/18)

They are gorgeous wheels, came very well packaged and the price could not be beat for forged monoblocks. Highly recommend!!

 

It definitely looks good but fitment was pretty tough. At some point I might try again and do some cutting. As far as the bottom tray goes, it fit fine with a dual T1R sparrow. There's about 3/4 in between the lowest part of the exhaust and the tray. I did cut a small 3in by 1 and a half in square from it to keep a corner of it from touching the exhaust. I might cut the extra threads of the mounting bolts off cause they are now the lowest point of my car and I can just see them hitting something and causing havok. I'm trying to add some more pics but the site is being annoying.

 

I had to trim some of the bumper where the driver side exhaust cutout is and i ended up using self tappers from the inside to close the gaps and secure it to the bumper. If I ever sell it, the bumper will have to go with it lol.

 

Mine is also secured with several body panel fasteners to the bumper.
