If by JCR, you are referring to exhaust fitting the diffuser, it’s hard to tell at this stage. If the JCR is valved, then we need more investigation to see if the valve diaphragm will clear. The race version exhaust will clear.

When you are ready to look into this, just PM me, and I'd be happy to assist. Doing my first DIY oil change today, so if you need some specific photos, let me know.

Quick question: Are you planning on wind-tunnel testing this and sharing the data once released? For any aero parts, I think this may be very important to many. For a road focused open tops like mine, I'm sure it would be fine, but for those with GT4 or GT4 RS, I'm assuming this would be a very important thing to know.

Here are some photos of the pipe area for your review. This is JCR full titanium system. for the rear pipe, it’s a valved non-silenced version for the 718 Spyder

A few photos from fit checking the first article wing mounts. The Stock wing is shown in lowest 1° AoA, and the 24mm Rise is shown in highest 7° AoA. Inventory planned for end of January for both standard and +24mm height, get your pre-orders in now and save with Free Shipping. Code RLFSBSA for free shipping on all pre-orders before Jan 26th! Also if there is any interest in a +38mm height version, reach out to us.

As for the Exhaust Diffusers, the final prototypes are in and fit tested with only a few minor tweaks.
Changes we've made include:
- A beefier Delrin outer vane for best durability and heat resistance. Vane optimized further.
- A short inner flange to increase diffuser panel stiffness and to cover the gaps to the center diffuser.
- Moved away from a sandwiched design to one that mounts outside the transmission cover at factory mounting points.
- Clearance for low hanging exhaust optimized, JCR Valved we're looking at you!
- All fasteners will be T25, like the factory fasteners.
- All mounting points are factory, no drilling or cutting required.
- Super easy installation and removal.

I just experimented with the higher angle of attack and removal of the front deflectors, and the car was noticeably slower on my home track (Harris Hill), so now I'm reluctant to mess with aero at all. Has anyone else had this experience? I know some people prefer the lower angle of attack without the front deflectors, which I also tried but still preferred the front deflectors in with the lower angle of attack.
