I love my SSP.

To touch on a few things:

1) My car sits extremely low. The rear brace won't be a point that scrapes because it's close to where the wheels are. As far as bolts scraping, well my front lip sits lower than the bolt mounting points so my lip scrapes first.

2) yes some bolts fit a little weird, but it's retarded fast to mount/take off if you have an electric drill or impact.

3) Trimming of the oem plastic pieces is easy and not an issue.

4) You don't need to install the panel over the center jacking point location. However, it's not difficult to install/remove. Just uses 10mm socket, takes me maybe 30 seconds. If you are using the center jacking point you are going to be doing some laying on the ground anyway.

5) The paint/powder coat isn't great. It's under the car though, so who cares

6) it has different venting for exhausting hot gases. I haven't had any temperature issues due to installing it. The oem underbody aerodynamics aren't very intricate from the factory anyway.

Anyway, if you want an alternative to the SSP and OEM you can check out the JUN. It's sexy af. But the SSP is definitely a way better choice than oem.
