VF-Engineering (VF Engineering) VAG (Audi / VW) type 4 chassis: MK4 1999-on 4 cylinder Engine Side Engine Mount. For all VAG type 4 chassis: MK4 1999 and up. All engines 1.8T/ Audi TT, A3, S3 (not DSG) VF Part#: VFA02-03. Description: The VW factory Engine side mount connects the engine to the chassis and was designed as a soft flexible mount, to provide a very comfortable drive. A drawback is the high amount of engine movement under torque load and on hard acceleration. This engine "slop" greatly decreases stability and smoothness under high performance driving conditions and rapid gear selection. The factory mount is constructed from a die-cast alumuminium mount which houses a large soft rubber bushes with a vulcanised cast strut. The rubber bush contains a viscous oil cavity to abosrb shock. The 1-piece OEM rubber bush does not completely fill the pocket inside the mount casing - leaving it prone to break under severe driving conditions. The drawback of the OEM design for 'performance minded' drivers is that long term stresses from power enhanced engines tends to cause premature wear of the both the driver and passenger side engine mounts: which either leak their viscous dampner becoming very sloppy or the aluminium casing cracks completely. VF-Engineering designed, tooled up and manufactured a complete new replacement, containing specially desinged molded high durometer polyurethane bushes. The mount is constructed from billet (ingot) aluminum and supplied with high tensile hardware. Billet is physically twice as strong as cast and this mount is designed for strength. Fitting should take no more than 60 minutes and fits all MK4 chassis including Golf, Jetta, Bora, Beetle, Audi TT, A3, S3. This high performance mount has been tested on a 250 whp turbo upgraded 1.8T Golf and VF found it provides a dramatic difference in the stability of the car when accelerating and braking hard. Gear changing under hard acceleration is also greatly enhanced. You will notice the difference.
