SPEC Flywheel - Aluminum: SPEC Flywheels are CNC manufactured at an unheard-of .001 tolerance, in an industry where the standard is .010. This precision manufacturing process ensures perfect balance and a perfectly flat bedding surface for the clutch disc, both of which also contribute to the ultimate in safety for competitive environments. All SPEC flywheels carry SFI certification.The automotive component most responsible for insuring optimum clutch performance and life is the flywheel. The flywheel's contribution to power transfer is three-fold.
Firstly, the flywheel should provide a consistent and friction enhancing surface for the clutch disc. Flywheels also aid in proper inertia, which is determined by the flywheel weight. Inertia controls the ratio of power to acceleration and can make a vehicle faster or slower based on gear ratio, tire type, vehicle weight, power output and even the location in the powerband output is achieved. The weight of a flywheel and amount of inertia it provides can also effect drivability. Lastly, the flywheel must provide a true balance at rpm, which means no dimensional runout that produces engine damaging and power robbing vibrations and allows smooth engine revolutions.
To allow for specific inertia needs, SPEC flywheels are made in high carbon billet steel and aircraft quality billet aluminum. The aluminum and most steel SPEC units are rebuildable and feature a replaceable steel friction plate that is made from a friction- enhancing steel metal specially formulated for optimum clutch bedding and holding power. The aluminum and steel materials provide a light and medium weight option for all types of racing. SPEC spends a lot of time and effort on research and development of optimum flywheel dimensions and weights for all types of driving and racing and can optimize your MOI (moment of inertia) to maximize your car's output and performance.2000 2003 AUDI A6 QUATTRO BASE V6 2.7 GAS FI T APB;BEL 6Spd Trans 2001 2005 AUDI ALLROAD QUATTRO BASE V6 2.7 GAS FI T APB;BEL 1999 2002 AUDI S4 BASE,AVANT V6 2.7 GAS FI T APB 2003 2004 VOLKSWAGEN PASSAT 4-MOTION;BASE W8 4.0 GAS FI N BDP

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart.
I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.
