I went a similar route as jonnkycvrd. Here is my mod list for HPDE's.
- Performance Based
- AP Racing Brake Kit from Essex with 3.12 pads - Castrol SFR Fluid
- Apex 19" Wheels (started with 20" but tire selection sucks)
- Elephant Racing Caster Pucks for the Front so I can run -2.5 camber
- Track Alignment
- CMS Half Cage and sub-belt mounts with Schroth Enduro 2x2 6-point Harnesses
- Rennline Wind Deflectors
- AWE ones moved the buffeting envelope from 100-120 mph but was will bad 120+ mph
- Rennline ones did a good enough job up to 160 mph (backstraight at VIR)
- Little Things that make it more enjoyable
- Designs By Jacob Seat Recliners
- RSpro Harness Collars
- Ed Guards Bolster and Headrest Covers
- HANS scratched headrests in previous track cars
- Lumbar Support for long days at the track - Below one fits the carbon buckets perfect
- GMG Center Muffler Delete with an Exhaust Valve Controller
- So I can hear myself 😁...my helmet has Comm Earmuffs built-in
- Hytorc Centerlock Gun as I am swapping wheels/brake pads a lot

On the 991.1 swift springs and tarett links. Use the fake seatbelt buckle inserts. Also take along my quickjack system for tire and brake work.

For those of you who switched to the AP Racing kit from Essex, how is livability with the car on the street (e.g., noise, dust, street pad options)? I just picked up a 16 GT3RS and still evaluating what I am going to do with the car. I really like the CCBs for the street
.I also plan on driving my car mostly on the street as I do have a dedicated track/race car (BMW). That being said, I would love to do a few track days.
I will chime in that I've been using MCS for a long time. On my BMW I recently went from a 2 way non remote to a 3 way remote setup and while it opens up a can of worms for suspension tuning, the confidence the suspension provides once dialed in is incredible. I 100% recommend MCS after many many track days. Just keep in mind that they need a rebuild every 100 hours or so (check the MCS site). 4 ways in the rear though will require some knowledgeable people for setup advice!

I run the Essex AP Racing on my 16 RS. One of the best investments I have made. I choose the Ferodo DS 3.12 for track and do not suffer from any extensive brake dust or grim. The PCCB's are nicely stored away on the shelf!
Absolutely no issues for the daily driving with excessive squealing or noise.
On track, just amazing feel, stopping, cooler temps, ease of use (pad swap).
I think essex tuning is running a pretty good November sale right now....
Overkill for the street, but if you start to track a great option to save the life span of the PCCB's.
Lastly, if you decide to move to 19's then one more reason to change.

The AP Racing brakes have been amazing on track. Off track I am swapping the wheels and tires back to stock so I swap the pads as well to Ferodo DS2500's. Swapping pads is SOO quick and easy on the AP Racing calipers....yet another reason why I picked up the kit.

I've never run my PCCB on my RS so I don't know the difference, but the AP definitely "tolerable" on the street. Maybe a touch loud loud at times and the odd squeak, but just normal "race car" sounds to me. I do notice in the cold(close to freezing) they take a bit to get some bite, so careful at the first few intersections while things warm up a touch. I believe they're a "free floating" pad, so no slide pins like regular calipers that pull that pad back once you release the brake pedal so I think sometimes you can hear/feel that slight contact at times.

Out of curiosity, is it possible to just change the front brakes to the AP setup and swap in steel rotors (girodisc) for the rear using the the stock CCB calipers? I wonder if 19s would work in the rear with the smaller caliper.

Regarding the pads and disc contact...As you're driving the suspension is constantly compressing, the disc is moving around laterally, and the pads are being pushed slightly away from the disc. Think of the seals in the caliper as a spring or hinge attached to the side of the piston, rather than just a ring through which the piston slides. In an AP Racing competition caliper, the groove in which the seal resides isn't a square cut groove.It has angles. When the pistons slide in or out there is friction between the outer piston wall and the seal, and the seal distorts a bit as shown in the illustration below. A caliper piston sliding out to the left would distort the seal in this manner (the slashes are the seals on either side of the piston):/

---
\
As the piston slides back in to the right, the seal does this:
\
---
---
/
There is a certain amount of tension or friction that needs to be overcome before the piston actually starts moving through the seal ring. That tension/friction keeps the piston from dragging on the disc once the pistons are pushed back into the bores by the disc/suspension movement.
Thanks again for your continued support gents!

Your car and my car are about to be twins. The Dundon Aero Package parts are shipping for mine this week. So excited for that one.
Back to the best mod for the track. The best you can do to help with confidence driving on the track is the MCS/Dundon Suspension Package especially on the 991.1 GT3RS. When Porsche came out with the 991.1 they used way to soft spring rates for the car and track use. I had one I bought new in 2016 and that was always my complaint with the car. Around the time the 991.2 GT3RS was released I was in talks with MCS about doing a suspension package for the 991.1 as I was planning on keeping my 991.1 for a bit. Then I got a 991.2 GT3RS allocation. That paused our talks for a bit but then they resumed when the 991.2 came in because that car was as comfortable on the street as my 991.1. That is where Dundon and MCS come in. I had the first set of shocks installed on my car and what a difference they made both street and track. For me the lap time wasn't that much faster at Road Atlanta with the MCS installed but it really made the car more comfortable and predictable to drive on the track. To dig up an old thread take at look at my response on how the car changed. It is a little long but I wanted to share the feedback I gave MCS and Dundon on the first initial package developed.
