improving aerodynamics with OEM parts

[Richn83]

ha ha, yeah it is nice unfortunately I didnt get to stop although fancied a spot of canoeing in the tarn valley which i guess is what you were doing?  The only pic I have is of the Aire at Milau but the geology is rather interesting even just seen from the car (several table top mountains and big valleys and gorges).

looks nice !!

Just a note regards the 2 longer side trims that come standard on the golfs ie the ones under the sills, I had to order both sides has after 3 years with coilovers it took its toll and they where destroyed any way the new ones are a superceded part and have bigger hump bits at the back similar to what it would be like with the 1a and 1b fitted but all in one.

I also have a new front undertray has I took it off some time ago and it went missing!! any way the car does seem much quieter at all speeds.

Got all the pieces on order but Audi had the TT parts in stock so the 2a and 2b are on the car,

I didn't realise until I was under the car that I have the silencer nr the rear axle due to having the GTI cat back I ordered no#3 on the list

Do I cancel them parts or try and fit them??? why dont I check before I buy things

  I DO know the feeling 

[Richn83]

With the front silencer on I think you might struggle to fit part 3 or have to chop it away into a much smaller piece.

I fitted the tank guard but have had to cable tie it on on one side"no fixing nr the exhaust side" any way I'm obviously going to have to drill it but I found this part number on ETKA N 910 011 01 - Blind rivet stud? I think this is to be inserted in the drilled hole then using a rivet gun squash then you have the fixing you need??

Does the above sound about right?

Darren

[the bruce]

On my 2008 GTI I did not need it.
If your GTI is older try it with drilling and insert the rivet.

Cheers Bruce stud ordered @ VW should be here Friday,

Now to sort the timing out on this engine, any one know about how to change the timing on a bkd 16valve engine

The Clio 197/200 has a very good and functional system that wouldn't be too far off a Golf's size. The 197's in particular is very cheap and easy to come by and testing has shown from 80mph upwards, it generates in the region of 40kgs of downforce. Compared to my old MK5, the Clio200 I had was glued to the track at high speed.

197


200

This looks serious !!
