I beg to diff. It most certainly will encourage more airflow. I already have everything there is to do with brake upgrades/cooling, plus some. 72-vane Paragon 2-piece floating discs, custom ducting, etc. etc. I even have GT3 brake ducts custom mounted to my control arms. My brakes don't have any issues with heat.

Stoptech doesn't offer their 2-piece setup anymore, but Paragon does, and it's a true floating setup, and they offer 48 or 72 vane setups. Real race grade discs and hardware, not tuner crap. Bolts right up to sport brakes.
My car literally has all the typical things to make it a track weapon, except decent OE ABS, lol.

All engine/tranny/subframe mounts
Ohlins suspension - custom valved by PSI
SPL control arms and monoballs all over
Swaybars
Oil cooler
PS cooler
Diff cooler - OS Giken LSD
3.92 R&P
Exedy Stage 1 Clutch and LW Flywheel kit
HFC's with Ecutek tune
AA shorty resonated exhaust
etc. etc. etc.

Good luck with that. Trackspec vents and ducting is money well spent. Stock brakes still have aluminum pistons in the calipers. You need to upgrade those also to AP racing stuff while you are at it. Don't waste your money just upgrading rotors. It's not worth it if you are serious about tracking. If your just playing around, you can get by. Do you have a fuel starvation solution?

Word to the wise.. Spool is one of the OGs and has one of the most ridiculous functional builds on here.

Word#2, you need to vent the hood. There is no other way to dump all the heat.

You need to vent to hood. No other way around it.

There are countless threads here about airflow and headlt reduction. The common theme is that heat needs to get out of the bay. Only way to do that is hood venting.

Appreciate the info. Yeah, mostly just playing around. I have AP Racing Pro5000R brakes on some of my other cars, so I get it. We used to use Racing Brakes Stainless steel pistons in our 987 race cars OE calipers with great results. Will see if they are willing to make some pistons for the sport brakes. If not, might do some AP stuff but for now car stops just fine.

This was the “first round” of upgrades and seeing how the car is on track to identify the weak spots. I track/race all my other cars too, so the Z doesn’t see tons of track time but I still want it prepared as good as it can.

But cutting holes in the hood just isn’t going to happen so I’ll just deal with it and do everything else. Oil temps aren’t really an issue on this car, 250-260 is fine with a high quality oil and thicker viscosity, with frequent changes. My brakes don’t have any issues for the tires I’m running. Coolant temps stay on 7 almost always, unless I stay out long in crazy heat, so that also easy to manage for the time being. But you know how it goes, we always are tinkering and wanting more! Lol. I’m

The ABS is the current limiting factor as I’m not going to run anything stickier than 200TW tires until I get a fix. Bosch Motorsport just got back to me about the ABS discussion so hoping to have some good news about that.

I'm running RacingBrake rotors, Ti heat shields, 3" cooling duct hose, 10/8 Carbotech brake pads. The heat generated with fry the dust seals in the calipers, Turn the powder coat a different color. And brake fluid will leak out of the bleeder screws. Have Mich Cup tires, 80TW. No ice mode yet.

Did you do the YAW sensor mod?

Did you do anything for the fuel starve on right hand turns?

Some CF hoods that are painted (with vents left exposed CF) look pretty clean, more so than the trackspec vents. Although I like the motorsports look with the track spec vents installed. I’ll be nervous to take a saw to the hood one day tho lol

Or one can always buy a spare hood.

CF hoods are hot and miss for fitment. Ask me how I know.

Cutting the hood isn't too difficult, we all did Ghostvette's vents half-drunk in about 2 hours

I sold my stock hold years back to get it out from under my bed for like $100. Now - I feel beyond stupid after I went sc - the amuse front is full and I have a cf hood with some venting. heating fun sure started last summer! I wish this had bigger/more vents. I would find some doorknob like me that would sell you a hood - cut that one up and keep yours if you don’t want to touch it. Good luck!
