More weight loss, more carbon! It doesn't fit perfectly though, the passenger side sits a bit high. I think the mold this company used is either slightly off or they released it from the mold too early. Worst case, I get ahold of Seibon or VIS racing and order a new hood from them down the line. The weight difference is significant though, can feel the front end is lightened up as the stock hood is like 60lbs and this one might be 10-12lbs
