Brake Cooling Ducts for Clio 2

If you are looking for a brake cooling option then look no further than corvette c6 brake ducts.

https://www.ebay.co.uk/itm/2005-201...-/281605705202?_trksid=p2349624.m46890.l49286

Bought these as a bit of a gamble and they fit absolutely perfectly. Even the mounting hole matches the front control arm brace on the body. Fit perfectly behind the fog light holes.

First mentioned them on our build thread but have seemed to be quite popular since putting it on our instagram page so thought I would add a separate thread.

They look great!
Might be difficult to fit on the mk3 cus of the washer bottle Liam

Be interesting to see how you get on with them though. Tempted to get some myself

Ebay special installed when I did the alternator to prevent that issue (as per your advice on 197.net), should arrive at the end of this month, if it doesn't work anyone want to buy them off me :ROFLMAO:

I purchased a set of these after seeing them on here.

How have you connected them to the bumper?

No I haven’t connected to the bumper as the bumper is quick release so still taking it off a fair amount. They sit tight against the original fog light housing though so don’t seem to move about much.

Evans Rallying have fitted them using the cup racer brake duct and have attached them.

I also bought these for the £75 (with taxes etc) off eBay after seeing your thread, easy to fit, however has taken me ages to get one to clear the tyres on full lock, the other side is fine. Ended up having to heat up the plastic and sort of ram and hold it in place with the wheel into a shape that worked, however I’m still very happy with them...

I had previously cut my cup racer ducts slightly so there is a slight gap between the ducts which is fine as I’m forever removing my front bumper. As for fitting I used the obvious mounting bolt along with an additional drilled hole up front as seen below, I also lobbed a cable tie around the center area purely to make it feel abit more solid.

When you say they caught on full lock, how mcuh did they catch by? And are you running normal range ET wheels or any spacers?

ET38 with 18mm spacers. I drove it for its MOT a mile down the road and noticed it, when I looked after it passed the tyre had started to melt through the plastic, it only just cleared it when I fitted it in the air, so I assume when the tyre had weight on it that was no longer the case and it was close enough to rub. Like I say I only had this problem on the off side, which I assume is either due to my fitting of it somehow or a manfacturing defect, not sure, a heat gun and a fair amount of time messing about with it sorted it in the end.

Those Evans Rallying pictures above look to be litrally just placed in there rather than mounted at all so I wonder how easy they found it with the far from well made renaultsport cup racer ducts, although it does look as though they have chopped off the front of the duct for more clearance as you can see how close they sit to my cup racer ducts and ive chopped half of the ducts off!

Dont get me wrong these are awesome and are easily the best solution ive come across thanks to @FPummell but they (for me at least) just took a few hours of messing with to get sat right. Lets see if they survive their first trackday on Tuesday :p

I'm glad someone took the jump before myself. I have been looking at these Corvette ducts for a while and working out if the design would work along with the brembo cooling brackets to run ducting directly to the caliper but looking at the picture the hole looks to run close to the caliper enough to produce decent cooling

As for rubbing what about allowing it to mark the area of rubbing and then heating it up with a heat gun and create an indent to allow for full lock?

I don’t think you read my full essay 😂 That’s basically what I did, heated it up, then created the extra space by putting a folded up rag tight in between the tyre and the duct where it was rubbing then held the wheel at full lock for a couple of minutes to bend the plastic to shape. I had previously just tried to heat it and bend it with various things in the garage with little luck.

I’m sure there are better ways to do this but i just wanted a way to do it in situ as I was fed up of taking them off constantly 😁

You kinda get a good idea of it from this pic, be it for the standard calipers

Great find @FPummell thank you.
Is anyone about to measure how far out from the chassis/frame this protrude towards the wheel? I’m trying to see if at full lock these won’t get caught by the tyre like happened to @Greeny. I’m running 15x7 ET35 wheel on a non cup 182 but don’t want to make fit or I’ll just fix up what I have already

@Mb21 for reference I’m running ET38 wheels with 18mm front spacers, cup packed 182 just had a larger hub and bearings though not a wider track, 172 cups only had a wider track from the factory due to their ET38 rims.

wishbone bolt holes on the subframe were slightly further out also

Thanks @Greeny. that doesn’t sound great for me as your running 15mm more front track.
If anyone and get me a measure of how far these ducts protrude outwards where the tyre is at full lock it be great

Measured from the front longitudinals the ducts stick out 40mm.

Are people running these on road cars too?

Just thinking they are easy enough to fit once you get to the track and then never need full lock.

Just for reference we are running et35 wheels, 205 tyres, Laguna hubs (about 5-10mm wider I believe) and no spacers. Just rubs at full lock.

I’ve got them on mine using some ducts made up by @04-182. Fit is perfect and they look good too. Mine caught very slightly running standard 182 wheels with 20mm spacers. I’ve got r888r tyres on though which do have quite chunky side walls. They took literally 2 minutes to push in slightly so they don’t run. An easier solution is to avoid full lock. Horn is in the way too but they are almost an oem solution

I suppose there's nothing stopping me cutting the front part out and leaving the rest!
