Thanks dudes! Not too shabby for a car a rattlecanned hood and most of the clearcoat missing, although I guess I'm biased Aero will come later on, maybe even after the engine swap. I think I'm going to do a GV lip then mount a splitter and wing at the same time. Diffuser will come later on after a few more projects.
By some stroke of luck, a set of DTC60 front pads showed up on my doorstep last night. Gonna have to see if I got double charged by the vendor or what but at least I'll be able to run front and rear DTC60s for the track this weekend rather than DTC30s in the front and no-name pads in the rear. I also finished up the install of the MadFabWorx oil filter perch and the cooler lines yesterday. No leaks so far and now I shouldn't have to worry about roasting my oil on track this weekend. Luckily the oil pressure and temperature sensor ports were close enough to my previous setup that I didn't have to extend any wiring after the install.
Old perch and sensor tee in the background.
Since installing the front wheels/tires/spacers, the car's got a mild intermittent vibration through the steering wheel that comes and goes at above 60mph. I checked the wheels and tires for balance and runout this morning and they passed, however the Roadforce machine says the tire stiffness is out of spec. I'm assuming this is just due to the stiffness and profile of the sidewalls and the fact that the tires also have some stretch. I overnighted a set of hubcentric rings (should've grabbed some already) and am going to check the spacers for runout this afternoon. I rotated the wheels and tires front to back this morning as well since I didn't notice any vibration from the rear while driving to SD this weekend with only the rear wheels/tires/spacers installed.
Got the ECUtek app troubleshot (troubleshooted?) and installed on my computer and am now just waiting for Fab9 to send my tune over. I'm not going to follow up on that as I really shouldn't add anything more to my plate this week haha.
For ECUtek, did you buy the full license? I.E. the one where you can actually go in and modify the tune through the cable?
My buddy is running it on his NC2, and unfortunately he bought the base one and we were only able to load the provided tune, and have no ability to modify the tune at all. I wish he would have bought the better license, as I wanted to get in there and play around. Curious to hear your reports on this.
Did a bunch of digging on this before pulling the trigger. The version I have allows for me to tweak the factory tune myself (but not any tunes supplied by an outside source), and has basically all functions unlocked for the end user to play with except for flex fuel, closed loop boost control, external/separate wideband control, and basically anything additional run off the can-bus. If you want access to play with everything yourself, you have to pony up for the $1,800 version of the software rather than the $500 version and at that point I guess I'd rather just buy a Haltech. I'm interested to play around with the factory tune myself but am hoping the prebuilt tune (and subsequent datalogging/tweaks by Fab9 if needed) just works well and takes one more thing off my platter as far as getting this thing race-ready. Fab9's done tunes for dozens, maybe hundreds of these cars, and the general feedback about working with their tuners seems positive. They also messed up almost every order I placed with them while buying parts for my VVT engine build, so I feel like I'm arguably throwing them a bone by deciding to work with them again.
Mini update. I rotated my wheels front to rear on my lunch break and swapped in all of the DTC-60 pads. Realized I installed all of my wheel spacers backwards too (inner chamfer facing away from the hub rather than toward it). I don't think the spacers were making contact with the hub lip at the base of the hub at all, it looked recessed behind the brake rotor, but maybe they were just barely touching with the wheel torqued down, causing a very minor wobble. At any rate, I took it for a short drive and got it up to 75mph a few times. Didn't feel any vibration again yet. I'm gonna take the car out to bed the pads in tonight or tomorrow and will hopefully confirm that said vibration is now gone for good.
Ha! Cursed by the vibration gods for eternity. Who knows what I did in my past life to deserve this.
In all seriousness, and I glossed over this in my first post, the car actually did have a vibration when I first picked it up. Got it up to 80mph on the freeway driving home and the tires were slightly out of balance causing a resonance in the front end. I could tell it was a balancing issue but still briefly considered driving it into a wall.
Got the car up to freeway speeds again on the way home yesterday. Vibration hasn’t come back. I’m pretty sure the ID of the wheel spacers were just barely making contact with the inner lips on the front hubs causing a miniscule amount of runout. The car’s officially ready to run laps this weekend.
You went over 75mph and didn't have a vibration? Time for a part out. This clearly isn't the car for you.

I'm glad to hear that. I can't imagine what thoughts you would have had if a vibration was still present. Looking forward to hear your thoughts after the next event.
