In goes the bimmerworld e36 pump to feed the bucket on the stock pump.
    can you expand more on this idea? i'm having the same fuel starvation just after i pass half tank too.

      Bimmerworld sells a kit that will pump fuel from the drivers side over to the passenger side where the main fuel pump will pick it up. We run it in our car as well. So far no issues, but we haven't been able to really push the new car to the limit yet with COVID.

          Being as my stock lines were leaking, I'm doing -10an lines and my cooler has the -10an male ends welded on, not the stock single bolt adaptor setup (you can order it either way). I have a bunch of -10an fittings already but I ran out of line so I'm waiting for that to come in :/

              uhh, haven't updated this in a while.

              Did a few events. Been having fun but also breaking shit. I'm highly not impressed with the Hard Motorsports splitter setup. It is shown over and over again with no splitter rods. Welp, at 140mph that wasn't happening. I heard it flapping away, pulled off. Damn thing was smiling at me. LOL

              Okay okay, I really should have known better. So I pulled the splitter off and ran the rest of the day with out. It definitely affected handling but meh, still fun:


              Best of the day was a 1:11x or 1:12x or something. Not too bad. That is on the AR1s.

              Anyway, made my own splitter rods and attachments and whatnot:

              And then promptly went out and smacked it on the deck when I completely blew my braking into the fast sweeper at Pocono... LOL again, I'm stupid.


              Splitter was fine-ish. No big deal. The HardMotorsports mounts aren't looking great. The previous no splitter rods fun started to fail the passenger side one, but lets just ignore that for now. The trip over the curb did bend something in the steering. The wheel was 5* to the right after the flight into the grass. Boy howdy was it fun though!

              So since I sorta broke the car, and I happen to have a z3 steering rack sitting at home already, I decided to go ahead and replace, well everything.

                I don't know at what mileage, because I never cared to look it up, but this car definitely had the bearing recall done at some point. At 116k miles now, 3 of the uppers were showing a tiny bit of copper. Luckily for me this engine has clearly been well maintained all it's life and had proper oil changes, evident by the color of the oil 'stains' in the pan and other key areas.

                It's all back together and ready to go again. It started up and sounded fine. I've yet to drive it though. I injured myself going over the bars of my MTB last week at one of the local mountains. When I'm all healed up I'll give it a drive, get the front toe re-aligned and head back to whatever track isn't covered in snow by that time.

                  Yeah...there is a learning curve with the splitter. I've finally stopped raping the splitter in the paddock over bumps and getting it on the trailer. My last plywood splitter has been holding up!

                  I mounted the splitter rods to the same location as yours. I've found that the reinforcement will flex quite a bit so I'm moving the rods to mount to the bottom of the kevlar bumper support. If you mount close to where the reinforcement bolts to the frame...it seems like there's less movement.

                    I've noticed this as well. Not overly concerned for now but figure I'll mount a camera at some point to see just how much deflection there is.

                    Kind of the reason I don't rush to get anything done on the m3; Donno what else you guys do/race but I've been getting back into the this after a few years out. Even picked up a win in the rain last time out:

                      Small update. I picked up a stock faded black hood, got the N15 vents from Lawrence who is an awesome dude and installed. I liked the side vents so much I ordered the front vent as well, but haven't installed it as the car is buried in snow right now.

                        The N15 vents are great! A plus when you support of fellow long time forum contributor while getting some value in return.

                          I owe this thread a small update. I've finished the hood with the addition of the front vent and some hood latches, with retaining the stock latches too. Click image for larger version  Name:	IMG_20210324_201120.jpg Views:	0 Size:	137.4 KB ID:	112257

                          I've also switch to a smaller rear wing. I had the Snead Speed wing sitting on my shelf already. The 9lives wang is great, but man it is huge. Since the car had a hint of mid corner push at high speed corners, I decided to try the smaller SS wing. So far, I'm liking it. Picked up a few MPH and the balance is better.

                          Other then that, just maintenance stuff. Using Girodisc pads now, changed a front wheel bearing and just been tracking whenever I can.

                              "G-Loc" pads - R16 fronts and R10 rears right now. I'll go more aggressive on the rears for my next set though.

                                Not too much new stuff going on with the car but I have been tracking it as much as I can during this very busy summer. I noticed some cracks forming on the original brembo front rotors so I replaced them with some girodisc rings. Mounted up some pirelli DH take offs I got for cheap. The sidewall height was a little higher than stock/ideal but meh, they worked amazingly well. Dropped my time vs the AR-1s by about 3% and there is more left in them as I figured out what pressures to run and how they liked to be driven.
