    Ricer = Object. (Est.-1990's?) A vehicle, usually of Japanese origin, front wheel drive drivetrain, engine displacement under 2 liters, in an inline configuration of 4 cylinders with weak horsepower & torque figures. But in extreme cases can be subjected to turbo charging and nitrous injection in an attempt to make vehicle faster. Other vehicle aspects are but not limited to: a round, chromed, straight-thru muffler with a chromed tip several inches bigger than the intermediate tailpipe. Sound is identical to a coffee can filled with bees or a hair comb covered with wax paper played like a harmonica. A wing mounted on the rear deck or trunk resembling an erector set. Some with multi wings to create more downforce to slow the vehicle down. Stickers on any part of the vehicle I.E. doors, fenders. Most common being "type R", "NOS", "APC" and various old english script.
    Headlights that give off a bluish color to simulate HID systems. Fog lights with identical light patterns. A body kit made of fiberglass or plastic that gives the vehicle more of a streamlined look and to aid in handling such as a high speed flyby after losing a race. An onboard audio/video system that can exceed the value of the car, with multiple amps, tv monitors, and various video gaming systems. A wheel & tire configuration with oversized chrome rims & low profile Z-rated tires to aid in high speed cornering in shopping mall parking lots.

    "1-Link" Referring to a suspension with (1) solid arm that locates the axle either in a 'U' or 'V' shape and comes together at one point on the frame with a ball style joint that allows the arm/axle to pivot from (1) point.

    "3-Link"  Referring to a suspension where the axle is located with (2) arms that run forward to the frame with a third bar that locates the axle from side to side.

    "4-Link" Referring to a suspension where the axle is located with (4) links that run forward to the frame to locate the axle.

    "Lincoln Locker" Referring to welded spider gears Ersatz (German word for "imitation") Locke, though in truth it's actually a crude (but effective) "Mini-spool".  It's called "Lincoln" not after the car, but rather than the Lincoln brand of Welding machines (The commonest welders)

    "T-L" refers to the Factory Limited slip differential - Trac-Lok.  Sometimes specifically referred to (when discussing 7.5" rear axles) as the "S-spring" Limited slip to separate it from the earlier POS (See above) that used conical clutches (Aka: Auburn)

    "Torsen" refers to the Gleeson-Torsen (old name) or Zexel-Torsen (Current name) Worm gear type limited slip diff (essentially copied by the Detroit "True-Trac")
