I love learning from the experience of others... learning from my own mistakes is expensive and slow. So please pardon my request for clarification on your too-simple-to-document setup... I'd like to know eggsactly what you're doing.
I can't parse this. Looking at the underside shots above, I see four attachment points for your splitter. I see the two L brackets that you describe, hung through the radiator opening via wire and turnbuckles. I also see two hangers in the middle and two bolts at the rear. I assume you're describing the middle attachment points? Are these "straps" merely Home Despot aluminum flat bar, bent in what appears to be a U at the bottom (no bolt) and hung from a random bolt on the chassis?
Thanks in advance for the clarification.
I can't really recommend using our method as a guide. It's a bit ghetto. A stronger strap material would be smart. But here you go: https://www.homedepot.com/p/Oatey-3-...3530/301505501
Two M5 bolts in the back thread into existing tapped holes in subframe.

Ah, OK, I get it now. I think I got tripped up when your original description transitioned from describing the front brackets to describing the middle attachment method.
Higher end sports cars have high resolution wheel position/ ride height sensors. Many other channels in new cars. Lots of temp and pressure sensors. Very useful when you can access it all.

Subbed and very interested in removing RF top motors for a true 4 point roll bar. I love how 949 Racing is continuing development for the ND, again, especially a 4 point roll bar solution for the ND.
Long summer break until next event in September so we're giving it some much needed maintenance along with some key upgrades. We didn't keep track of the exact number, but we estimate its had at least 60 sessions on it since February. Motor is out for the SPS/Piper cams and valve springs. While the motor is out, we'll probably do a valve job and rehone. Oil sent off to Blackstone. OS Giken diff getting some adjustments to the tune.
Mods already done over the last few events:
All PU inner bushings and all spherical bearing outer bushings swapped in
Seat position tweaked to be more centered behind wheel
Racequip formula car belts swapped for Schroth Enduro belts
330mm Guardian alcantara wrapped wheel
Install Competition Hubs F& R
Stuff for September event:
Roof mech and motors coming out
Pipercams, mild rebuild
Retune OSG diff
Master cylinder brace
Prototype brake cooling deflectors
Bump from16/8 kg springs to 18/9kg
Progress on the one-off roll bar being built by Renderos Racing. Also removed all the mechs, linkage and motors for the roof. 94 lbs worth. More than offset the weight of the bar which should be about 35 lbs.
Looking forward to driving it again with the cams and tune from SPS Motorsport. Should make about 190whp on gas and might get over 200whp once we figure out flexfueling.
Single diagonal with harness bar. He's making reinforced foot plates.
Random bracket, or maybe one of the foot plates. Just nice work.
Can't wait to see the times it puts down with even less weight and mo' powa! Still blows me away that the car put down a 1:57 at Chuck with basically stock power, although obviously Sonny being behind the wheel was a big factor
94lbs of roof motors!! Holy cow. Did you fab up the lexan fastback glass yet? Excited to see that part!
We skipped that bit for now. The stuff we did was fairly easy to figure out and low hanging fruit. The fastback requires a bunch more design and fab work, for a lot less functional gain. We're putting it off so we can get the car running sooner.
As soon as I saw this car was under development, I was waiting on this number, but I never expected it to be that much. I never fancied that version of the car anyway, but knowing that figure I would definitely steer (sorry) away from it were I to be looking for an ND.

Huevo was great that day, really locked in. As fast as it was though, we had probably another 1~1.5s in it just in suspension related changes. The needed parts have been modified and installed now. Looking forward to getting it back on track to continue development.
I stand corrected on the rear window/fastback part. Alex is going to do that while its there. I wasn't sure he would have enough time, but he wants to do it.
We had a few ideas but never locked any one down. The rear sail panels end just past the leading edge of the trunk. So any window sitting on the top of those panels couldn't be easily sealed against the body.
Multiple ways around that problem including cutting and shaping the bottom of the window, setting the window further down between the sails, making a functional inner sealing structure underneath the main window panel.
We'll see what he comes up with.
The retractable glass window with defroster, its frame and motor will be gone so we have to weather seal the whole thing from scratch
