How to retro-fit skid trays, aerodynamic under trays, & stone guards to a MK7 Golf

[parapraxis24]

Finally got a good drive in yesterday after installing the panels, and wow what a difference. The car feels so much more stable at highway speeds, it isn’t affected by wind turbulence from leading cars/trucks like it was before. Sometimes I’d feel like the wind would push it side to side, that didn’t happen at all yesterday in my 60+ highway mile trip.

Any wind noise I was hearing from below the belt line, seems to have mostly vanished. Blizzaks are really loud at highway speeds lol.

My roof rack is also definitely not as quiet as I thought it was! Now that nearly all wind noise from the lower half has been eliminated/reduced, it’s really obvious now. I guess before it would blend together into one breeze, so I gotta figure out something with that, or just live with it maybe.

Thanks Dave!

Sorry for another dumb question, but will the long front exhaust cover reduce performance at the track? Anyone who did these mods and track notice anything? I saw heat soak mentioned on here a couple times.

My previous long front cover after a track day (cover had absolutely nothing to do with the failure):

If anything it will be an improvement in drag/lift, due to not having a pocket of air pushing up into the engine. I would get one of the parts with the transmission ducting since they're there, but the tray does nothing to keep the engine warm once air is moving through your heat exchangers. The factory racecars run a big aluminum skidplate all the way to the subframe.

That's the exhaust cover? Damn what happened. You must have freaked out seeing all that metal.

Sorry, no, just the tray. I have a front exhaust cover somewhere but I didn't see the point.

The only people who saw heat problems was a UK member who made up his own full length exhaust tunnel cover.....the OEM one only covers the front half of the exhaust tunnel....There is also the rear exhaust tunnel cover, with sits to the side of the fuel tank...again its factory designed & no heat soak issues have ever been reported by members who track their cars...

Do you also have a tray / guard fixed between the two guards?

I run the ECS skid plate and full length exhaust tunnel, and the OEM rear exhaust cover. Have run that setup at the track with absolutely no issues. Nothing got hot, nothing melted and there is absolutely no way that impacted oil temps in anyway.
I also run the same setup in stop and go city traffic. No issues there either.

I tried to do the rear axle cover last weekend, but ran into some fitment issues with the short cover (1K0 501 713D) on my 2018. The edge that rests along the underside of the gas tank doesn't quite fit. I couldn't get the plastic nut to thread onto the new stud/bracket without really forcing it. Since the nut is plastic it would pop out since I could only get a few threads started.

I'll need to trim it down and try again when it stops raining.
