Cut about half a second and ran a 1:35.7. The theoretical looks good at 1:35.1 with decent confidence, but there were a few things keeping me from being consistent.

1. Brake pedal looses a ton of bite as the session goes on and the pedal gets considerably longer. This makes threshold braking really difficult because the bite point keeps moving around. I'm gonna do a total brake fluid flush with something better than the ATE typ 200 that's in there now. I also want to rig up air deflectors on the tie rods to funnel some air onto the rotor (like the ones Vorshlag makes).

2. As a result of the soft pedal, I ended up flat spotting my tires a little. These RT615k+'s are at or below the wear bars anyway, so I think it's time to throw on the RS4s and get a more aggressive alignment.

3. I need a harness badly. The 3pt on this Corbeau is definitely better than stock, but my torso still flops around a bunch. Giving point-bys while turning is super dangerous because I'm still pushing against the steering wheel to stay upright. I'll try to rig up my eBay harness bar and a 5/6 pt despite being very dangerous in a rollover.

Car did great overall though. This was my first time running with the Advanced group in this particular club and goddam the pace was fast. Thankfully I wasn't the slowest in the group, but I was definitely on the slower end of the spectrum. I'm not used to this lol.

still looks fast and fun

Awesome, thanks for sharing great in car video.
^^^ I'd have to agree, it looks like kick in the ass fun.

Got my RS4s mounted up.

New fancy racing brake fluid and synthetic gear oil are in. It's medium weight and I added 1oz of friction modifier, might need more though. I didn't realize the old gear oil already had modifier in it (weird for a conventional to have that), plus I added a whole 4oz bottle which is probably why it has felt kinda loose on exit.

Attachment 40464

Oil temp gauge is wired up (nice).

Attachment 40465

Booger-welded the wideband bung in. Haven't gotten around to wiring up the AEM yet. I also made a small heat shield to keep exhaust heat away from the rear brake line.

Attachment 40466

New timing cover seals installed dry. Didn't realize these PTFE seals on the opti and water pump shouldn't be oiled on install. That could be why they leaked. Also did a new cap and rotor on the opti.

Attachment 40467

Also tried blocking the openings next to the radiator with some garolite sheet (fuel line epoxied on the edges so it doesn't jack up the plastic radiator tanks).I'm trying to see if I can force more air into the radiator and hopefully keep temps down as it climbs to 210 on occasion.

Went to regrease my Founders LCAs with the 3pc bushings and found that the center ball had swelled. They are super tight in the bores and don't rotate easy. This basically makes them as useless as regular poly arms, so I ordered some Spohn rod ended LCAs.

Attachment 40470

New muffler too because the glasspack is too loud. I love the sound of it, but it's hard to threshold brake when you can't hear what the tires are doing.

Attachment 40471

Other than finishing the wideband and the LCA fiasco, all I really need is to do is set the alignment. I'm back on track next Wednesday so I need to get my shit together asap.

Keep us posted on if you see any help from the air dam mods

Got the LCAs on and the ride is definitely clunkier. Not that impressed with Spohn's system for converting a 3/4" rod end for use here. The bushings are 3pcs (1 sleeve and 2 centering spacers), but the fit is kinda loose everywhere and the sleeve is too short for my liking. I ordered some 2pc Allstar adapters that will hopefully have better tolerances and less slop, otherwise I'll fab some.

I was able to get my car on the alignment rack. Here's where I started...

Attachment 40474

I lost some camber when the Ridetechs raised the front of the car. Here's where it's sitting now...

Attachment 40473

Didn't have enough time to dial up the caster, but 5deg ain't bad. I did a rough calculation that showed I'm only missing out on <0.1deg of camber gain with the wheel turned at 3 or 9 o'clock (most turns) vs. 6deg, so I'm not too concerned. Steering still feels very direct and I'm ready for Lightning this week.

Track day ended up getting rained out. Didn't get a good idea of what these new tires feel like, if the alignment is any better, what my oil temps top out at... etc. But I did find out that the WOT fueling goes pig rich as the sessions go on and I sometimes see the wideband dip into the 10's under load. See below vid of me shooting flames lol.

As it turns out, the BLMs do not necessarily lock at 128/128 in PE. I believe the PCM is able to add fuel here but never subtract it. I'm not entirely sure how or why it does it being that narrowbands aren't going to show anything useful, but I'd imagine the mega rich condition has something to do with my 4-5k rpm false knock.

I applied a WOT BLM locker patch from $EEX which will hopefully prevent the fuel from wandering all over the place. I also bought a flow matched set of Bosch 36's to replace the mismatched set that was on there to make sure every cylinder is happy.

Also.... I think the opti shit the bed right after the last track day. The car would run great for a while and then start violently breaking up once heat soaked. ICM/coil swap didn't help and everything in the datalog looked perfect. Jiggling harness wires didn't do anything either. I ended up chucking my Camaro's old Delco onto it and it hasn't given me any grief... yet.

So the last track day at NJMP was meh... it was too hot and I didn't run anything good.

BUT I did make a 5hr trip north to Palmer Motorsports Park in MA this weekend. Apparently it has the steepest grades of any track in all of North America. It's carved into the side of a mountain and video doesn't really do it justice.

Awesome, I like the new MPH setup, gives you a better perspective while viewing. Before I was always trying to catch glimpses of your speedometer.
Thanks for sharing, very cool. Nice countryside up there, temp must have been good. It's so hot down here everybody is staying inside in the AC.

So I added the GPS speedometer last minute because I forgot to plug my HUD in on the last session. The HUD wasn't helping me here though lol, track is too dense.

And it was in the mid 80's that day, but EMRA (the racing org) requires long sleeves and pants for insurance purposes. It was toasty in there.

More meh times at NJMP. Traffic was rough, but I also think I had too much camber as the inside shoulder was wearing much faster than the outside.

I just put the car back on the alignment rack and dropped the camber from -2.7 to -2.1. I also spent the whole weekend tearing weight out of the car and netted about 50lbs so far.

Attachment 40502

I have a suede Grant wheel in the mail which should get me another few lbs and am going to order a PC680 batt from FCP Euro so I can return it when it dies lol. I am going to wait until winter to pull the ABS block, gut the dash, install ozite carpet, etc.

Attachment 40503

I also picked up this Trans Am hatch because I'm going to be building a lexan spoiler on the back. I need to crack my Lightning PB from last year or I'm gonna lose my shit!!!!
