The SPF3907K insert design does not require removal of the rear subframe to service. Each insert slides into the existing OEM rubber bushing housing after the mounting bolt is removed, stiffening the subframe mount without the labor-intensive subframe drop required for complete bushing replacement. The four SuperPro polyurethane inserts reinforce the original rubber bushings from within, reducing the lateral and longitudinal flex in the rear crossmember that allows the BRZ and GT86 platform rear end to shift under cornering loads. The result is sharper turn-in response, more predictable rear end behavior under load, and reduced NVH from a more rigidly located subframe. SuperPro's engineering-grade polyurethane compound is resistant to heat, oils, and road chemicals, and the SPF3907K carries SuperPro's lifetime warranty on the polyurethane bushing range.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Design Requires No Subframe Removal:\u003c\/strong\u003e The SPF3907K inserts slide into the existing OEM bushing housing one bolt at a time, eliminating the extensive labor required for full bushing replacement on the BRZ and GT86 platform.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Bushing Inserts Included:\u003c\/strong\u003e Complete kit covers all four rear crossmember mounting positions for a full subframe stiffening upgrade in one purchase.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Subframe Flex Under Load:\u003c\/strong\u003e Polyurethane inserts eliminate the lateral and longitudinal compliance in the factory rubber mounts that causes rear end movement during cornering and braking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved Turn-In and Rear End Predictability:\u003c\/strong\u003e A more rigidly located rear crossmember translates to sharper steering response and more consistent rear traction behavior on the BRZ and GT86 chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperPro Polyurethane Compound:\u003c\/strong\u003e Resists degradation from heat, road oils, and weathering that reduces the stiffening effect of rubber inserts over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLifetime Warranty:\u003c\/strong\u003e SuperPro backs the SPF3907K polyurethane bushing kit with a lifetime warranty against defects in materials and workmanship.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e4 x SuperPro SPF3907K Rear Crossmember Polyurethane Insert Bushings\u003c\/li\u003e\n\u003cli\u003eSuperPro polyurethane installation grease\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number (MPN)\u003c\/td\u003e\n\u003ctd\u003eSPF3907K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e9317745039075\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSuperPro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit Type\u003c\/td\u003e\n\u003ctd\u003eRear Crossmember Insert Enhancement Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit Contents\u003c\/td\u003e\n\u003ctd\u003e4 Polyurethane Insert Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter\u003c\/td\u003e\n\u003ctd\u003e31.70 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner Diameter\u003c\/td\u003e\n\u003ctd\u003e20.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e32.50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Dimensions\u003c\/td\u003e\n\u003ctd\u003e8 in.

With the bolt removed, the existing OEM rubber bushing housing has enough movement to allow the SPF3907K polyurethane insert to be slid into position inside the factory bushing. Apply the included polyurethane grease to the insert surfaces, seat the insert, and reinstall the mounting bolt. Repeat for each of the four mounting positions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill I need a wheel alignment after installing the SPF3907K?\u003c\/strong\u003e\u003cbr\u003eA wheel alignment is recommended after any rear suspension modification on the BRZ and GT86 platform. A four-wheel alignment after installation ensures optimal tire wear and handling balance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs the SPF3907K appropriate for a BRZ or GT86 that is used for track driving?\u003c\/strong\u003e\u003cbr\u003eYes. The SPF3907K is well-suited for street and track dual-use applications on the BRZ, GT86, GR86, and FR-S. The stiffened rear crossmember mounts reduce the chassis flex that can cause inconsistent rear end behavior during repeated hard cornering on track.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow many bushings come in the SPF3907K kit?\u003c\/strong\u003e\u003cbr\u003eThe SPF3907K kit contains four polyurethane insert bushings, one for each of the four rear crossmember mounting positions on the BRZ, GT86, GR86, and FR-S platform.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes the SPF3907K also cover the front subframe mounts?\u003c\/strong\u003e\u003cbr\u003eNo. The SPF3907K is specifically engineered for the rear crossmember mounting positions. SuperPro offers separate part numbers for front subframe bushing applications on these vehicles.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch4\u003eInstall Instructions\u003c\/h4\u003e\n\u003cp\u003eSafely lift and support the vehicle on jack stands with full access to the rear crossmember. Locate the four rear subframe mounting bolts where the crossmember connects to the chassis. Working one bolt at a time, loosen and remove the first mounting bolt. With the bolt removed, the OEM bushing housing will have slight movement. Apply the included SuperPro polyurethane grease to the outside surfaces of the SPF3907K insert bushing. Slide the insert into the OEM rubber bushing housing, orienting it as directed by the SuperPro instruction sheet included in the kit. Reinstall and torque the mounting bolt to factory specification before moving to the next position. Repeat this process for all four mounting positions, completing one at a time to keep the subframe stable throughout the installation. Lower the vehicle and perform a four-wheel alignment before returning the vehicle to normal use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCalifornia Proposition 65 Warning:\u003c\/strong\u003e This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects, or other reproductive harm.
