improving aerodynamics with OEM parts

[Snoopy]

A very interesting thread.    
After spending ages/money and many gallons on waxoyling my mk6 adding all these aero covers would just add to the protection.

I was disapointed in the standard engine bay cover of the mk6.  

Apart from number (3) at the rear until i change the exhaust i think i can fit them all to my car?

The engine cover im not sure about from the photo as the mk6 has triangular bits that stick down at the sides screwed to the front bumper, that also support the inner front wheel arch covers and the engine undertray in place. Is the mk5 the same?


Does anyone have a full list of the parts needed for all these modification and some guide prices in the UK?

Thanks for a great thread that really interests me

Hello Geoff,

yes, part #3 will fit only if there's a smaller center exhaust (like Eisenmann or Supersprint)
or no center exhaust (like TDI or the Scirocco R) or you have an non-resonated system.

The engine bay cover and all the other parts do fit the Mk.VI as well. I know Golf VI owners
that did this mod. And the pic with the numbers shows a Golf VI 2.0 TDI.

There are many parts. But just the larger parts front and rear in my list (that Robin posted)
are really easy to fit. So they're recommended.

Thank you. 
Are there any other covers i could also use under there that would add to protection ?

Complicated to fit is not a problem, i use to work in the motor trade and have full garage facilities (lifts etc) of my own.

Sorry to be such a pain. The sides of the new undertray to its sides looks like the bottoms of the inner wheel arches not connected to anything? Im guessing this is part way through fitting and its just lower as it looks that way and its not a different fitment? Its that long since i looked at the front of mine and been under too many other VAGproducts since to remember correctly
Just want to make sure before i contact TPS to order the parts.

2a and 2b comes from Audi A3 and TT 8J (fwd only).
Nr.3 comes from TDI BlueMotion and is best to be used with an non-resonated exhaust.
Nr.4 is ''Hinterachsverkleidung'' from TDI Blue Motion.

1a and 1b, The mk6 has triangular bits there from the factory, im not sure of the mk5, are these to make them bigger or just add to the mk5?

Front and sides the same (old) screws als OEM are used. No difference.

The Mk.5 has them as well. But 1a and 1b are larger and cover the smaller ones perfectly.
I don't know if they fit the Mk.6.

There are protectors for the lower wishbones as well. Never seen them on my own.

fitted all my parts today will see if it makes a difference

[Poppa Dom]

Be interested in your findings Aaron, considering doing this myself

[RedRobin]

^^^^
How are you guys going to avoid the placebo effect and assess the difference? I may be wrong but aren't any differences going to feel very subtle and you would need a proper wind tunnel to know the facts?

[Aaron_RJ]

your right robin just interested to see if it affects mpg

[RedRobin]

.
I'm not suggesting that they won't be of benefit though - Just tricky to accurately assess. Even accurate mpg without proper monitoring equipment might be unreliable due to so many everyday driving variables, imo.

[Aaron_RJ]

Very true but I drive the same road at the same time with no traffic everyday will let you know tommorow

Needs some CFD. Anyone got a laser scanner?
