I didn't let the header situation keep me down this weekend. I spent Saturday and Sunday with the car on the lift and successfully installed

-RaceComp Engineering hollow front and rear sway bars
-Whiteline Com-C top mounts (revised version with better bearings and harder durometer rubber around the bearing, acquired via warranty replacement)
-Whiteline rear crossmember insert bushings (KDT922)
-Millers Motorsport CRX 75w90 NT Trans & Diff fluid
-Millers Racing Brake Fluid 300 Plus (flushed all the OEM fluid)
-Project Mu HC+800 Brake Pads (F&R)
-Perrin Rear Shifter Bushing

No malfunctions, everything installed without a hitch. Test driving the car after doing all of that was FUN! Zero body roll from the bigger, stiffer and hollow RCE sway bars set stiffer in the rear and softer in front for predictable oversteery goodness. I am amazed by how much grippier the stock tires feel when tossing the car around. The bars help the car change direction quicker than I ever thought possible. It's a truly amazing difference in handling compared to the OEM sways. Can't wait to see what kind of cornering speeds these allow on the track soon. Thanks @Racecomp Engineering , you guys rock!

Quicker, more responsive turn-in with more negative camber and caster from the WL Com-C top mounts. They are working great with the RCE Yellow springs on the OEM struts. Took the camber bolts out of the strut mounts and went with the stock fat-collared bolts because I'm getting enough negative camber already. No noises when turning or over bumps, no deformation of the rubber around the bearings; they check out and earn a thumbs up.

The Whiteline rear subframe bushings also make the car feel much better under load. All the rear subframe slop and play is gone. The chassis responds instantly to the gas pedal and traction is greatly improved everywhere. Coupled with the Perrin rear shifter bushing the car feels more solid overall and the gear changes feel more precise and direct. No additional NVH that I noticed so these bushings get two thumbs up

I haven't gotten to threshold test the Millers racing brake fluid yet but I will at the next HPDE at the end of April. The brakes feel awesome, much more progressive bite from the Project Mu HC+800 pads. They feel much more aggressive compared to the StopTech Street performance pads and since they have a much higher MOT and friction coefficient they will hopefully serve me well at the track soon and allow quiet operation year round. The trans and diff fluid are performing great so far. Quieter, smoother shifts and lower operating temps by a significant margin makes me feel good about tracking the car hard this summer.

I didn't get any pics during the install of anything since I was just too focused on getting it all done ASAP, but I did manage to snap a quick one after the test drive after washing and before putting the 944 Turbo S (pictured) and 944 S2 race car back into the garage:

Now for the only bit of bad news...

I did not successfully install the Touge Factory Brake Cooling Duct kit. The instructions require drilling and cutting a hole in the factory splash guard right where the control arm sits and removing the calipers, rotors, and hubs to install the backing plates for the hoses. The kit comes with shims to push the washer fluid tank out to create a big enough gap between the tank and the AC condenser and line on the driver's side to route the hoses.

With the car on the lift, I removed all the under panels and installed the spacers for the washer tank and made the gap per the instructions and attempted to test fit both of the ducts on either side of the bumper opening to be sure they would work before proceeding with the rest of the install. I was concerned about the differences of the bumper openings on BRZ vs the FR-S. Touge Factory developed the kit on an FR-S and the unique grille mesh and the bigger lower openings near the "fangs" happen to be just right for the ducts to be secured and the hose to be routed properly. I found that the BRZ bumper does not allow proper fitment of the ducts and hoses.

I could not find way to properly mount the ducts to the BRZ's bumper. This is mostly an issue on the driver's side. I could not find a way to mount the ducts flush with the bumper opening and zip tie it down securely while allowing the hose to properly flow into the gap between the washer fluid tank and the AC condenser/rad. The FR-S bumper openings are perfectly shaped at the lower extremes to allow the ducts to mount flush and direct the hoses to just the right area to clear the condenser on either side. The mesh design grille on the FR-S also makes it much easier to zip tie and secure the ducts. I decided at that point to not install the kit since I couldn't find a good solution to securely mount the ducts behind the bumper cover openings so I decided not to proceed with installing the backing plates and cutting and drilling the splash guard for the hoses.

I will be contacting Touge Factory first to see if they have a solution. Everything else about the kit would have installed fine, but the differences in the bumpers between the two cars may be a deal breaker.
