In conclusion:

Im not going to lie, it feels like its been a slog. A job i really wanted to do but so glad i broke it down into segments. To do properly just takes so much time and you can easily get carried away just rushing it as its pretty laborious.
The boot and back end took me a week of evenings, the doors were a morning each and the interior cabin was a solid day. So you would need a good few days spare to do it. Of course im using my car in between time, so if you were to strip the car fully and run through the job, start to finish it would be quicker. I also was upgrading audio at the same time, routing cables, speakers etc.

Sound wise inside now, its odd as its still very much a Clio, but the doors sound different when they shut, as does the boot. The sound of the central locking has a deeper tone to it and it feels generally tighter and a bit more premium. All of the Clio'ness is still there and there's no doubting what car you're still in. Blindfolded you wouldn't all of a sudden think you're in a modern car for example. But all of the hums, rattles and buzzes that stiff Clio makes is significantly reduced.
Road noise is down massively and everything going on is more muffled and less aggressive. Yet there's still all the snap, crackle and pop from the ITG Maxogen and PMS de-catted system. Its still all there, just a bit smoother if that makes sense.

I had previously been testing the ambient noise inside the car with an iPhone app, but since my last test, i have swapped over to my summer tyres which as anyone who has used R888Rs will know, they're bloody noisy. So any results i got this morning were purely for fun to see how much improvement had been made.

I was surprised with the following results, these are the average dB readings inside the car under the following conditions.
  • Decibel X app
  • iPhone screen mounted phone holder
  • Same section of road - A127 (A130 to Wickford)
  • 5th gear
  • Cruise control set to 50mph


  • Totally untreated car (Michelin PS3) = 82.6dB
  • Rear cabin & boot floor treated (Michelin PS3)=77.3dB
  • As above plus doors treated (Michelin PS3) =74.2dB
  • As above plus front cabin floor treated (Toyo R888R) =72.4dB
  • Total drop in ambient road noise -10.2dB!

Now i know the results are flawed, but as said before, i didn't need an iPhone app to tell me how much better it has made the car. A total drop of over 10dB and that's with noisy rubber on too, its made a noticeable difference to how nice the car is to be in day to day. However one issue is my previously vary quiet PMS shifter is now the loudest thing in the car and i will be forced to revisit shutting it up if i can.

All in its cost me about £140 for the sound deadening materials used and including the audio i have added approx. just under 20kg to the car.

Previous results and this mornings results posted below :)

Actually, I've just checked regarding weights.
Deadening was 8kg Dodo Hex, 3.5kg Noico 2mm, 2kg of Super liner. So less audio, if anyone wanted to do the same without audio its approx 13.5kg to do the whole car. I had a tiny bit left over but for weight purposes is negligible.

amazing! I had thought about this the other day as I only take the Trophy out on long drives and when sitting at 72/73mph the RPM creeps up to around 3400rpm which can get a little annoying after a while. I've got a yozzasport on my car so have thought about putting some deadening under the rear seat and boot floor to quieten it down even a smidge. You've definitely given me some ideas.

You’ll be amazed if you was to just do the boot, tailgate and rear bench at how much better it will be.

New mats and filter service on the Maxogen. Takes bloody ages to flush out all the old oil, even with the correct ITG cleaning solution, but worth it when you see the junk one of these collects in 20k of road miles. Should be good for a further 20k now.

Whole under bonnet area looks immaculate. Fabulous attention to detail. Well done!

Finally got some time to look at fitting my Corvette brake ducts today. Although these are exceptionally close to an OEM fit, they do not fit right up on a road car.
There was a lot of fitting, warming, forming, tweeking in order to get these to clear certain parts of the chassis, align with the fogs and provide tyre clearance on lock.
i used a hot air gun and a steel tube to mold recesses and clearance curves in the tubes so they didn’t foul on anything. Plastic oem trim rivets we’re used to pin them to the crash beam. Trimmed the arch liners to fit those back in too. Eventually I got a fit that I was reasonably happy with and good tyre clearance on lock.
Now i just need to sort some finishers between the fog light bumper trims and duct tubes.

That sounds and looks like a very challenging install but the end result looks very O.E.M. and will I’m sure provide the directional cooling that you are after.

It will be interesting to know over time if you find benefit under extreme driving conditions.

Well done! Really nice work??

Thanks.
I’m not going to lie, it was a good few hours of cocking about. The bumper went on and off about a dozen times to make sure they were sitting as good as they possibly could be.
I had to relocate the horns further up to provide clearance and alter the formings to stop the tyres catching on full lock. There really is very little room on a road car. If it were a face car I’d have just cut and drilled the body and altered parts to get them in, but I didn’t want that.
I may still run a direct hose from the outlets to back of the discs.

I keep toying with the idea of a more thermally efficient caliper design but I think the OEMs will work well enough if you can manage the heat effectively.

Good work. I’m sure the short duct route to the brakes will definitely aid cooling to the calipers.
182s always look mean and nasty without front fogs.

So, delighted with the fit/function of the Corvette ducts, I needed to address the finishing on the front of the car. So I contacted @04-182 about 3D printing me some finishers that fit into the OEM fog surrounds that also locate into the GM pieces.
A little back and forth with measurements and test pieces and I think we have something thats as close to OEM as I’m likely to get. Function wise they would in theory get more air by having some protruding scoops on the front of the ducts but I think so far, all I’ve seen look a bit naff.
Ive also shared some other ideas with Simon (04-182) so hopefully some nice improvements coming.
Dead happy with the fit of these though, theyre bang on what I was hoping to achieve. Thanks Simon. ???

Looks ace. I knew I recognised your car, I follow you on Instagram and messaged you a while ago about the sound deadening project. I've now bought the stuff to do similar to my Trophy, as although my Prospeed exhaust looks great, it's a little too loud and has a really horrible resonating noise if you lift at high RPM. Hoping the sound deadening will help with this, removing the rear seat definitely didn't help with things!

Do you use your car on track at all? I do with mine a fair bit and the brakes do get hot and a little spongy. I think I'll probably be copying your ducting before long, I've upgraded to Motul 660 fluid and DS1.11 pads (from DS2500) so will see how they fair next time out

Ha great stuff. I certainly do track it, I’m actually at Snetterton on Tuesday. 🙂👌🏼
