Let's start with the front ones since these are the easiest!   

I'm afraid that this is pretty much a wheel off job, although it might be possible to do it with the wheel on, you'll find it a lot easier with the wheel removed. I started doing it with the wheel on, but ended up taking the wheels off part way through!

Once you've jacked the car up and removed the wheel, make sure that the area that the mud flap goes onto is nice and clean and dry. The mudflap has a section of double sided sticky tape which needs to bond onto the wing to make a good fit.

You'll see 3 little plugs on the plastic insert (circled below ), you need to remove the bottom 2. To do this push something small into the centre to push through the small pin (don't worry about where it goes - you wont need them and they'll end up falling out themselves), and then lever out the plug itself.

Now under the sideskirt there is also a plastic screw thing with a torx head, this also needs to be removed. It unscrews, so unscrew it!   

Now you can test fit the mudflap (don't remove the backing tape yet!), and you'll see that the two upper holes on the mudflap can line up with the two plugs you've removed. And the little notch on the other side will fit in the gap between the wind and the side skirt.

Have 2 of the replacement plug/pin things ready and remove the backing tape from the inside of the mudflap. Now slide the mudflap into place and use the 2 plugs to hold it in the correct position. You can press where the tape is to make sure it sticks to the bodywork. Now push the pins until the end is flush with the head of the plug. And then screw in the large plastic screw underneath - don't overtighten, it's only plastic!!. (The mudflaps come with a large push in plug which I think you could also use underneath, but I decided to use the screw in one instead!) 

Now the final hole on the inner wing needs a screw into the plastic. Take one of the black screws that came with the mudflaps, and screw it through the remaining hole! You don't need to pre-drill it as the end of the screw has a drill type end to allow it to cut through the plastic.

If you've taken the wheel off, now go and give the inside rim of the alloy a good clean!

Put the wheel back on, lower the car and admire your handiwork!   

Do the other side in exactly the same way

Now for the slightly more tricky back mudflaps...

(The pictures seem to be out of order, but you should get the idea!)

I'd recommend starting with the side opposite the exhaust - this is beacuse the exhaust side has a tricky little bracket which provides additional support. If you get the non-exhaust side done first it'll put you in a better position to understand the other side!

Again, I'd say remove the wheel to make life a little easier!!

Right - the rear mudflaps are two piece, so split them (mine arrived already joined! ) by pushing the pins through the plugs, only this time make sure and find and keep all the pins!!

First we need to mount the inner part. Remove the two 8mm bolts on the fuzzy inner liner, and put the inner part in place, securing it with the bolt you removed! This was a complete pain to do and requires you to really push the whole thing back to get the thread to catch! :mad: 

Once this is in place, test fit the outer part. I found it easier to start with the bottom inside part and slide it up and round into place! 

Remove the backing tape, and fit the outer part, using the plugs to hold it in the right place. Insert the pins and push them home.

Use the other bolt you removed to secure the top part of the mudflap to the inner lining. This is also a pain to get in place but persevere and you'll get there!!

Now finally use one of the supplied self tapping screws to secure the mudflap underneath.

Again clean the inner rim of your alloys, and put it all back together!

For the other side, the process is exacly the same, but instead of putting a self tapping screw in the bottom, you need to use the support bracket supplied. This bracket bolts on from the bottom and through the fuzzy lining with 2 bolts, and seems to press up on a mounting screw for the exhaust heat shield. This is a little hard to explain, but from the picture below, I hope you'll be able to figure out how it fits!

And you're done!
