Seen it too... Komet brace is intentionally not carbon fibre, and the spacer setup makes it a lot better than screwing it directly onto the chassis (tested on track).
Also the komet brace goes over the front assembly posts, making it stronger also in that area (I had a chassis that was bent there, even though you would think it is rigid there). You do need to drill extra holes, but you don't need new front posts
