Getting ready for the Cupra R rear conversion

Well, as the weather was sort of 'nice' today in Essex I thought I'd start on the mission of the Cupra R conversion. I thought I'd put together a proper guide with pics as no one seems to have actually put up any useful info !

The new spare valence arrived at the dealer the other day, and the second hand Cupra R rear bottom part came Friday at work.

Now as far as I'm aware there isn't any template for cutting the rear FR/Cupra valence, so out came the marker pen and a couple of new stanley blades

Simple job to lay the 'R' part over the new valence

The plastic is quite tough, so if you have a dremel then it will be MUCH easier. I cut two rough holes then enlarged them as necessary, not massively neat but as I'm going to seal it all up from behind I wasn't fussed !

Then I spent ages sanding down the upper valence so it completely smooth, as I'm having the whole rear painted white. Took ages to get rid of the rough texture, but some 600 grade wet and dry sorted it !

Next stage is to key up the lower part and then get it bonded onto the upper half. I'll then give it to the bodyshop to paint for me.

Ordered the rear box from Dave @ Sera Saturday, so the rear box should be here during the week.

I'll post up some more pics of when I remove the original valence and also when we cut off the 'old' rear box.

OK, well spent all evening keying up the bottom part of the valence ready to primer up, bit of a mission due to loads of little angles etc, but its coming along nicely. Still a little bit more rubbing down to do on the very ends and leading top edge tomorrow / Thursday. Must go get some more 600grade wet and dry

Big thanks goes to Dave @ Sere for the super fast delivery of the backbox.
Even though I have a trade account with Remus in the UK, the Cupra R box is made especially by Remus for Seat, so I was a little 'annoyed' that I couldn't buy it from Remus UK ! Well Dave managed to sort out the proper 'Seat' part for me !
Build quality is fine, I have seen better and I've certainly seen a lot worse though. The exhaust comes with full fitting instructions on how to cut the rear valence/bumper assembly with a 3 page printout of diagrams showing where to cut the original exhaust and all of the bumper assembly.

For those of you wondering if I've had the end tips gold plated - the simple answer is NO !!! Its just the lighting in our warehouse that makes it look like that ! However I'm toying with having the tips painted gloss black as a contrast to the bumper all being white!

Helpfull diy. The paintshop should be pleased. I did several valences so far but it isn't nescesary to make it completely smooth since the paintshop will use filler which will smoothen out the surface anyway.
Good tip is to ask them to use a filler/primer in the same colour as the top layer (I did several in inferi black so I used black filler).
I you want a central backbox this is the way to go (since plastic welding to put some fins on will be expensive).
If you want left or a left right exhaust the new Lester diffuser will fit just as fine as the MS diffuser (at only half the price).

Well I decided to rub it down as in all honesty the 'factory' paint job done on the Cupra R rear I've seen in the showroom is shockingly bad !

And especially as mine is being painted Candy White !

It shows as a separate pipe as the cars come in as a Cupra and then has the 'end' box added, whereas Dave was saying all the Cupra / Fr etc etc are all one piece systems.

I would think you'll have a right old bidding war if you put it on Ebay !!

I see a lot of people 'wanting' to do the conversion, but its expensive for what it really is, especially when allowing for a new rear valence and painting and fitting if you cannot do any of this yourself.

Even one of the dealers on here is charging I think £695 fitted (not painted white, just standard gloss black as they can do it before hand) and of course it doesn't stop at £695 as you'll need to tell the insurance company.

I think the backbox is a seperate item, the one I have from mine when the R parts were fitted looks lile a neat cut otherwise!

I would have put up pics but the dealer did mine pre-delivery as they its all covered under warranty and the like that way.

Nice writeup so far though

The Milltek rear silencer should be available shortly after the development work is completed on Craigs car.

My diffuser is sitting painted and waiting :)

Yep I do. I also know the downpipe will be the same on the Cupra R as it is for the BWJ k04 Pre Facelift Cupra based on same basic engine design and identical turbo :)

unfortunatley Milltek won't be doing a backbox delete (straight pipe) to fit this diffuser... :(

Why would you want that though? The car would end up sounding like a stock car and would surely not be road legal especially with the non resonated centre section.
