You have shown PTFE thread tape in use on your oil cooler fittings, you don't want that on there.

If you undo the fitting & take it off you will see why, it threads up & can get drawn in in strings & cause blockages.

PTFE tape should only ever be used on tapered thread forms such as BSP(T) or NPT as it is the threads that for the seal, on the AN fittings that you have used the cone on the top of the fitting is the sealing surface.

Many thanks for the info as i have not fitted an oil cooler before so was thinking PTFE would be good to stop any leeks but can now see that this is not needed after reading in to AN fitting types and how they work .

I owe you a beer

So last night i removed the PTFE tape from the oil cooler AN fixing and re fitted all the fixing as per E-BMW advise .

I also had some time to fit some new Airtec brake cooling guides .


As the stock set up struggles on track with heat they should help out a lot combined with the bigger brakes and pads .





Ad installed a nice easy upgrade .








Its the same type as the Boomba unit below that shows how the help with the airflow .

You could look at replacing front fogs for ducting to brakes. That is what I run:

I did look in to this but want to keep the front fog lights and the air deflectors are a quick and easy install .

It's a track car, what use are fog lights beyond weight and something to break? I mean each to their own, it's your car but even so... seems a bit pointless..

[kaveney]

Think i can live with the weight of around 0.5 Kg for the fog lights as the car will not be a striped out car ( iv done that before ) and will still be driven to all tracks so some road driving and as the air deflectors do the same job whats the point of getting ducting .

A good read so far. Looks like the front grille is partially blocked off? Might be worth opening up the blanking off.

Without wanting to sound too much like a patronising dick you mix up your leeks and leaks, cheep and cheap.

[kaveney]

I will see how i get on and if i get any cooling issues but it is something i have seen before along with drilling holes in the front bumper .

its only 3 years old so i would rather not attack the bodywork just yet but will see how we go .

Noted on the grammar and i will try and not get pulled by the spelling police again

I felt like those wind deflectors likely wouldn't do anything. There isn't really enough channeling to effectively move air to a target as far as I can see.

But, to be honest, I haven't scientifcally tested anything, so my solution could also be pants. It was easy though, 3 screws per fog light and a plug. Could do it by unscrewing a bit of the arch liner.

Looks to flow air well enough in the below vid to the discs but we will see .

Huh, good video. That does represent what it does quite well actually. I'm surprised.

Small update

I will be looking to install a big AP racing brake kit and have done some prep work fr this .

First is to remove the brake dust cover as i will be looking to get more air flow to the discs using cool air ducts .

OEM brake dust cover




And removed

Without the shield, the cable for the ABS will get heated on-track by the disc and start to melt. Either cut the piece of shield that goes between disc and cable and refit, or fit high temp cable/hose covers.

Ask me how I know

Hmm, my '13 plate never came with heat shields. They were added later.

I've tracked my car since 2015 and had no issues whatsoever!

[kaveney]

Good Shout and i will look to get some high temp hose to protect the ABS cable .

Might be a problem with the big brake kit ?

For about £ 5.00 i will get some high heat hose just to be on the safe side .

Got a few more bits done at the weekend .

I have been told that the OEM rear rear beam to chassis bush is a bit soft and can move a bit so have replaced this with a Powerflex unit .

New Powerflex unit

Getting the old unit out was easy enough .

New Powerflex unit installed

[s2tommi]

Great build, some top quality parts being used, looking forward to seeing it on track

[alex98uk]

Did you follow any guide on changing the rear beam bushes? Would be interested in doing so myself.

[kaveney]

Getting there and she runs fine no leaking so getting there .
