This Recaro sub-frame (part number 866916) fits the Audi A4 from December 2000 to 2007. That covers the B6 and B7 generations, a period that included the B6 S4 with its 4.2 V8 and the B7 RS4 with the naturally aspirated 4.2 V8 that many regard as one of the finest road engines Audi made. The sub-frame uses the A4’s factory floor mounts with no drilling or modification required.
The A4 is a larger car than the A3, with a longer footwell and a different seat height relationship to the seatbelt anchor points. Generic side mounts in this car frequently sit too high for comfortable use. The Recaro sub-frame is engineered to the A4’s floor geometry, keeping the seat at the correct height and angle for the OEM belt system. Fore-aft runners are included.
Fits base-mountable Recaro seats. Not for side-mounted competition shells without adaption hardware. One sub-frame, one seat position. Order twice and note your seat model at checkout.
