I will play with it some this week. My suspension is still off the car and it's on jack stands in my garage so I can take some pictures and measure and maybe try to come up with something. I know dbyrd has ducts with his Mporium undertray but deansbimmer had to custom fabricate a solution to fit the ducts as well.

I am thinking I cut the ducts and somehow shove some of the brake ducting tubing in the gap on top of the tray. Or maybe use some of these https://new.minimania.com/part/NMB40...Mini-Cooper--S somewhere on the back. Idk

Take a look at Pinnacle Motorsports alu undertray. It's basically the mPorium (which I have) with cutouts for a GT4 lip. Instead of trying to sell/ship mine and rebuy the Pinnacle I'll be looking to make what I already have work by mimicking what Pinnacle has done.

I also feel the GT4 lip has the brake ducts facing to much into the wheel well, and in turn it is harder to route the tubing without having it run into the tire. But maybe it is fine as well.

That undertray does look pretty useful with ducts.

In my limited experience with racetracks, I can say that changes in elevation are what makes a circuit great.

Agreed, flat tracks get old fast.

I was loving the elevation changes.

I live 40 minutes from NOLA which is dead flat. I have driven more laps in the last 2 years at VIR and Road Atlanta which are 14 and 9 hours from the house, respectively, because they have so much more character and are so much more fun to drive.

Kimi's start was the best part

Agree with the elevation changes, but wanted to hear more about NOLA. The first WRL race of 2021 is there in January, and we're planning on running it.

£215/$280 USD seems like a great price for the Pinnacle undertray. What's the drawback?

What I didn't know is that Hankook Motorsports has exclusive stock for whatever reason (probably to keep stock for their LuckyDog and endurance races they sponsor) Anyways, they have tons of 275/35/18 for $245each and October is free shipping promo so I ended up with $980 shipped.

for daily+track use? mostly daily?

That you have to wait a few extra days to get it from the UK? I've heard nothing but great reviews otherwise.

His half cage looks super legit as well!

Agree, that was amazing. It looked like a video game set on easy mode. Carlos' charge up the front was impressive as well.

Is there a legitimate two piece rear rotor option for our cars or only with a BBK?

AFAIK PFC never made the rear DD rotors for E92, only E46. GiroDisc was front only, too.

Turner released a set recently that I posted about in the suspension/brakes section a couple months ago, but it doesn't look like they sell replacement rings which is the whole point of the purchase anyway... I just emailed GiroDisc to see if they might ever sell a set for the rear. They only have fronts. I think previously they said they would but needed a 10person GB to do it. RacingBrake sells the rears only but for the price maybe OEM FCP euro is a better option. https://racingbrake.com/bmw-irk-03

$2200 is the sale price for the rear RB rotor setup!? You're like 75% of the way to a BBK at that point.

You have to go in and select the options. Rear rotors only, no pads is $1,013. Replacement rings are $632

That price is front and rear. Rear only is half of that. I'm not crazy about RB. I've seen and heard too many mixed reviews when compared to someone like PFC, Brembo, Girodisc, etc

I agree. There's a serious hole in the market here.

If RB is $1000 I'd happily pay up to $1500 from a bigger name with a better reputation especially if you can easily replace rings.

[b4hand]

These are about $2200 for the rear, https://trinityautosports.com/stopte...t-bmw-e9x-m3-1
