The rear underbody is where most of the aerodynamic work happens at speed. Airflow exiting the underbody at the rear creates a low-pressure zone that can either work for the car's stability or against it depending on how it is managed. The TYPE-S rear under spoiler directs that exit flow to reduce rear lift and improve rear-axle downforce.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecs \u0026amp; Highlights\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRear under spoiler \/ diffuser extension\u003c\/li\u003e\n\u003cli\u003eManages underbody exit airflow\u003c\/li\u003e\n\u003cli\u003eReduces rear lift at speed\u003c\/li\u003e\n\u003cli\u003ePart of the TYPE-S aero family for the 2022+ GR86\/BRZ\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction\u003c\/li\u003e\n\u003cli\u003eFitment: 2022+ Subaru BRZ \/ Toyota GR86\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003e40mm Extension, 5-8 kg Downforce, 15 kg Lift Reduction\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe rear under spoiler extends the lower rear bumper lip by approximately 40mm downward and 25mm rearward, directing underbody exit flow at a more favorable angle relative to the road surface. HKS's published contribution for this piece in isolation is approximately 5–8 kg of rear downforce at 200 km\/h. Its more significant contribution is reducing rear lift, the factory rear undertray exits flow in a way that creates negative downforce (lift) at speed, and the under spoiler reduces this lift by approximately 15 kg at 200 km\/h.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/products\/85ccda97e701ad14bce4ca256027e653.jpg?v=1697648535\" alt=\"HKS TYPE-S Rear Under Spoiler - 2022+ Subaru BRZ \/ Toyota GR86\" style=\"float: left; width: 40%; max-width: 300px; height: auto; margin: 0 20px 16px 0;\"\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eRear Underbody Exit Flow Management\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe rear under spoiler is most effective when paired with the front TYPE-S pieces. Front aero and rear aero work together to manage the pressure balance under the car from entry to exit. Running only rear aero can shift the aerodynamic balance toward understeer at speed; running front and rear together is how HKS tuned the TYPE-S system.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/products\/be25cf5241f598c6c42ef7c8e1d3a47e.jpg?v=1697648535\" alt=\"HKS TYPE-S Rear Under Spoiler - 2022+ Subaru BRZ \/ Toyota GR86\" style=\"max-width: 100%; height: auto; display: block; margin: 20px 0;\"\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eBest Effect When Paired with Front TYPE-S Aero\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eShips unpainted for body-color or contrast finish application.

It does most of its work out of direct sight, managing underbody flow exit at the rear. For GR86 and BRZ owners building toward the complete TYPE-S aero setup, this piece closes out the rear of the car. The 15 kg lift reduction is arguably more important than the 5–8 kg downforce addition for street driving. Reducing lift at the rear makes the car feel more planted and stable at speed in a way that the driver notices as improved confidence rather than identifiable downforce. The 40mm extension is a small physical change that produces a disproportionate aerodynamic benefit at the rear.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":52621288341784,"sku":"HKS53004-AT024","price":495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/75mnrjb782f1_00bce0aa-a472-49dc-9a96-2ba87c00b40c.jpg?v=1788748011","url":"https:\/\/driveforges.com\/products\/hks-type-s-rear-under-spoiler-2022-subaru-brz-toyota-gr86-ccqdpa","provider":"Drive Forge","version":"1.0","type":"link"}
