I just wanted to let you know that my clamping kit from Dustin arrived a few weeks ago.

I will start building the ducts as soon as the snow melts, I still have the winter tires on my Mini. I'll update the build with pics, I have a few ideas which I think has not been covered in this thread yet.

Let's see how the cooling ducts affects my heat issues. I'll let you know!

Ok, lets update some!

I mounted a 3" cooling pipe from the fogs to Dustins mounting plate. Everything fitted fine, one problem though, a 3" pipe/hose is way to big to fit behind the strut. So I cut it off and just let it exit similar to the JCW kit. Diffirence is that 3" are a little bigger than the JCW kit.

I had one track day so far with it, everything worked very well driving 10-15 min sessions. But I still had the stock pads on, I guess the XP10s will generate more heat.

I can also add that the track I drove on isn't to bad on the brakes.

I will try to fit a 2" hose instead soon.

Next track day is on Saturday, I will have the XP10s on by then. This track is also heavier on the brakes. I will post my results here after the weekend.

The XP10's will generate a bit more heat--but it really depends on you tires.

You should be at the right operating heat range for race pads such as the XP10. That is why I am starting to think about how to put in some duct covers so during the cool (cold) track day mornings, I can block them off to bring up the heat in the brakes.

I can add that I am currently running Yokohama A048. Last season I ran Toyo R888. The Yokos seems to have a much better "structure" (sorry, don't know the english word for it). They seem to hold their shape better during high load (when cornering on the track).

Highly recommended!

(I have been trying to upload some images of the brake ducts, but it seems really slow atm)

Peter_s,

You are running stock pads with Yoko A048 r-comps. Lucky you did not fry the stock pads.

I ran XP8s last season with the Toyos (bought XP10s this year). I just ran the stock pads this trackday, my Carbotechs were stuck on an airplane because of some ash in the air.

The stock pads worked pretty well actually, it was right below 50 deg F outside and I didn't drive with much attack (just because of the pads). The cooling ducts seemed to do their jobs. but as I said: This track is pretty easy on the brakes. You only reach 70 mph one one part of the track, and there are only two braking points with some distance in between.

Terrible grammar and translation with google translate :D :

That sounds like a lower speed track and you were pretty prudent with the stockers.

When you get a chance, please show some pics.

I'm trying to upload, but It just says: Waiting for northamer..... I'll try again later.

You can enjoy this vid from the track in the meantime:

Slinger: Yes, it's a pretty fun track. Lots of sweeping bends so it's pretty quick (not in top speed though). Suits the Mini well, but which track doesn't


Finally the picture upload works! Bad luck last time I suppose

Edit: regarding the speeds at the track, that should be 110 mph, not 70 Miscalculated some, it's 170km/h

That looks more correct at 110 mph. Looked a whole lot faster than 70 mph to me.

You look like you are still running stock calipers. I am currently running them as well with XP12s but will go to Wilwood sometime soon.

Yes, the stockers are pretty good.

I got to try the new setup today (ducts + XP10).
It was raining and it was slippery like crazy so there was not possible to test to the limit.

And also, it seems like my valve chain tensioner broke. Car had to be collected by a tow truck and I was able to ride with someone else home. I was really lucky that it started in the pits and not out on the track, a possible valve salad was prevented.

Sorry to hear about the tensioner.

I think ducts and XP10s are good. I ran that as well. I just found that the XP10s seem to wear down much faster at the track than XP12s.

Nice video! Good to see the Clubman can hang with some pretty fast company. What was the yellow car you were following for most of the second half of the video?

Thanks, yeah the Clubman is a underdog
I'm very impressed by the performance on track, I did not expect it to be as fast when I bought it. I believe the yellow/white car is an Opel Kadett, late seventies/early eighties. I spoke to the owner and it has a 2 litre rally engine and it's weight reduced to around 900kg if I remember correctly. It was really well sorted, he is four wheel drifting through the bends

Slinger: How are the XP12s on the street? I find the XP10s worse than the XP8s when they are cold (not really surprised ). And damn the 10s squeal...

XP12 are really noisy on the street. You draw a lot of attention when you stop. But they stop OK when they are cold.

I said I would update, and now I finally have run a "normal" sprint track with my brake ducts.

The ducts seems to be working very well with the XP10s, it's a big differene compared to last year. The brakes didn't get "mushy" after 10-15 minutes.

Only after 15 min+ and loosing my ABS on the track, I felt some difference. Then my bad braking technique without ABS made the pedal a little spongy.

But I have more confidence in my brakes now, and I'm sure I can improve the cooling even more. And my XP10s doesn't even look worn after 1 day at a rainy track, half a day at the Nurburgring and one full dry trackday.

The XP8s wore out after 2-3 trackdays last year.

XP 10 last about 4-5 dry days for me. XP 12 last 5-6 days. I think the heat range is better for the XP 12s.

Kind of off topic but ... does rotor wear go up as you go up the scale from XP8 to XP10 to XP12 ... ?

Yes.

But if you run a pad that is outside it's temperature range, it'll fade, and I've had problems with pad deposits running a pad that's not aggressive enough. One thing to keep in mind is tires make a huge difference--street tires, I could run XP10's (heck, might even be able to run XP8's) with no problem. With R-comps, It's XP12's on the fronts. I run XP8's on the rears though--this combo has worked out the best for me.


Slinger does better with pads than I do. I can get 3 full days out of the XP12's, maybe four...

I have worn them down to the rivets a couple of times.

I may have been slightly optimistic with the pad wear for the stock calipers.

Ok boys and girls....I've started my brake duct kit project. I got the Sneed Speed kit and have these pics to share as of now. I'm am still waiting for the rest of the kit to show up (inlet ducts, they were out of them) and the new rotors. But most of the hard part is done....

Cutting the radiator support was easy with a dremmel - cuts like butta! Still need to ziptie the hose after I get the bumper remounted. And course I have to lose the fog lights... :-((
