8E0 825 267      a spreader rivet £0.12 (need 4 so x4)




What does the rivet go into, that would worry me a bit! (just dont trust myself) and how easy would these parts be to fit on axle stands on a drive as I dont have the luxury of a ramp  :sad1:

Also any feedback Aaron?

Had mine on axle stands today for something else and to me it looks like the rivet fits in a hole on the arm thats easy accessable with the wheel off. :smiley:

hi sorry for no reply oops

not noticed any difference in consupmtion easy enough to fit on axle stands , the rivets are plastic nd when rear stone guards are fitted the go through the guard and suspension arm and splay out

I had the bolts from VW, but don't hesitate and use some standard ones.
Just take care it's zink plated or similar.

....I think stainless steel bolts would probably be best of all.

Of course, feel free to use stainless.
First I wrote ''stainless'', but I changed it for ''Zink plated or similar'' before clicking the button. :signLOL:
I try to avoid shiny bolts on, in and under the car (with the exception of exhaust).

....Any particular reason?

My thinking would be to achieve the best durability. Titanium might be rather expensive!

Not even at mototrway speeds?  hmm maybe there is somethign else about the GTI that affects the airflow like the front splitter making the air turbulent at the front removing the effectiveness of the smoother under-body....  :confused:

The only reason is that I like to have it looking OEM where possible.  :wink:

Titanium bolts would be nice, not too expensive when standard M8 and no too hard
to get, but are there any benefits at this place?
We should save weight where it counts: at the front, so a carbon bonnet and placing
the battery in the rear will make a remarkable difference for example.

....Well, I've got the carbon bonnet and might consider carbon wings but too much hassle to move the battery to the boot. Also, too much hassle to keep having to recharge a compact lightweight battery alternative.

You can see that my car is well beyond looking OEM although I do like to kid myself that it's kind of OEM Plus.

To be honest, so far I'm not convinced that the underside aerodynamic parts being discussed are of any real benefit at all apart from perhaps protection.
