GT4/Sypder/GT4RS/SRS Aero Developement Thread - Blue Spot Autowerks
We all know that the Porsche 718 GT4 is an exceptional vehicle straight from the showroom, ready to conquer the racetrack. Yet, as any enthusiast knows, there's always room for improvement. One area that caught my attention was the car's Aero package. While the factory rear wing provided two settings for downforce adjustment, I craved more.
Exploring options to enhance downforce, I initially considered raising the rear wing. However, I aimed for a balance that wouldn't compromise the low downforce setting or the car's aesthetics. Further research revealed an alternative – additional Angle of Attack (AoA) settings by incorporating more mounting hole positions to the wing riser brackets. And so, the journey to combine reasonable extra height with an additional AoA position began. The Phases of Innovation: Phase 1: Model and Study I meticulously studied and fully modeled the factory riser bracket in 3D CAD, drawing on my extensive career experience. The result was a model aligned with the OEM's published AoA settings, serving as a baseline for design. Phase 2: Integration of Changes I extended the vertical supports by 24mm, providing extra height, and simultaneously reinforced them to handle potential increased downforce values. An additional front mounting hole was added to achieve 3 degrees of AoA from the factory high-downforce setting. https://images.squarespace-cdn.com/c...g?format=1000w Phase 3: Prototyping Utilizing my FDM 3D printer, I created initial parts in ABS, refining the design through multiple iterations. The fit was commendable, prompting a move to the next phase. https://images.squarespace-cdn.com/c...pg?format=500w https://images.squarespace-cdn.com/c...pg?format=500w https://images.squarespace-cdn.com/c...pg?format=500w https://images.squarespace-cdn.com/c...pg?format=500w Phase 4: Functional PrototypeOutsourcing work, I had a set of risers crafted in Aluminum alloy, undergoing test fits, finishing touches, and a sleek Flat Black paint job. The moment of truth arrived as I mounted them onto the car, marveling at the transformation. https://images.squarespace-cdn.com/c...pg?format=500w https://images.squarespace-cdn.com/c...pg?format=500w Phase 5: Real-world Testing Venturing into the real world, I tested the risers through street driving, autocross, and track days at Portland International Raceway. With around 100 laps on the prototypes, each lap hitting approximately 140 MPH twice, the risers proved sturdy, showcasing noticeable changes in aero balance, especially in high speed turns. https://images.squarespace-cdn.com/c...pg?format=750w https://images.squarespace-cdn.com/c...pg?format=750w Phase 6: Refinement and Community Feedback Incorporating valuable feedback from the community, I refined the design, enhancing visual aspects, and offering both standard and 24mm taller versions to cater to diverse preferences within the GT4 community. The initial production parts are expected to be available later this week or next. Stay tuned for updates on the final product, which will be posted here. https://images.squarespace-cdn.com/c...g?format=2500w Final Phase: Business VentureThe positive response to the riser brackets, coupled with the demand for additional products, led to the realization that Blue Spot Autowerks was more than just a passion project. In the latter part of 2023, I formalized plans for the launch of Blue Spot Autowerks, marking the beginning of an exciting venture into the world of high-performance automotive enhancements.

Nice! I was thinking of developing a product like this actually :) seems like you guys beat me to it. Looking forward to the results. Will it be able to work with aftermarket mufflers?

Am I right in saying that the "standard" part in the center is essentially what MR does for the rear wing aero?

These will only fit when cars with aftermarket exhausts with no lower chamber. Stock and Akrapovic are examples with known fitment interference issues. We cannot check all aftermarket exhausts for fitment, but the donor car for development has a Kline system. The diffuser is constructed from 5052 Aluminum, while the vanes boast impact-resistant PVC for durability. The Aluminum will be powder coated matte black.

Both products look useful- looking forward to learning price point and availability!

That makes sense about exhaust with no lower chambers. Have you guys tested heat from the pipes/muffler? Will the actual pieces have any ventilation?

Looks great! Don't know if it's beyond your remit, but I suspect many buyers would be getting these in lieu of aftermarket wing risers, as they're easier to install and the "tall" option bumps the height a decent amount. Given that, it'd probably be useful to have some kind of size comparison between the tall version and, say, the BBi and RSNV risers.

We will be doing some more install images, we can try to highlight best we can. Generally most upright risers are +3-3.5 inches I know of one at +80mm. Our tall version is +24mm or almost 1” rise.
