We started with a new chassis (TKR5407).  The ET48 and NT48 proved that moving weight forward results in better cornering so we eliminated the rear engine configuration from the NT48.3 and concentrated on optimizing the handling and flex characteristics of the front engine layout.  This improved the gear mesh between the clutch bell and new 46t spur gear (TKR5119) and also helped to calm the rear of the car.Another area that received an update was the braking.  Larger, fully CNC machined, hardened, and ground discs (TKR5345B) replace the old parts.  Improved semi-metallic brake pads (TKR5314B) are now separated by springs (TKR5368) to ensure the brakes are only engaged when you want them to be.  The biggest change made to the brakes however, is with the linkage (TKR5336B).  An all new brake system was designed for better consistency and easier brake bias adjustments.New rear hubs (TKR5199) allow the option of using the stock CV axles or upcoming universal driveshafts.  We now also offer the rear hubs in aluminum as an option (TKR5199A).  At the front of the vehicle are new trailing steering spindles (TKR5193) and spindle carriers (TKR5194).  The trailing components vastly improve high speed bump handling in addition to smoothing out the steering response.  The vehicle initiates turns more predictably and finishes corners better than ever before.  Larger bearings are now fitted to the front spindles for improved durability.  The spindles will also accommodate upcoming universal driveshafts.The V2 hinge pin braces (TKR5161, TKR5162, TKR5163, TKR5164, TKR5165) have found their way into the new kit.  They provide more adjustability than ever before.  For example, changing the roll centers at the hinge pin is now an easy task and allows you to set up the vehicle for any track conditions.  Front arm sweep, kick-up, rear anti-squat, and rear toe are all adjustable.Our low profile wing mount (TKR5181) is included to lower the CG of the whole vehicle.  A revised front bumper (TKR5166) increases front ground clearance.  Straight camber link rod ends (TKR5187) were produced to improve consistency in corners. Clamping spring perches (TKR6140) and new shock boots (TKR6144, TKR6145) are included to keep the shocks clean, smooth, and trouble free.Finally, the box setup has been tuned by some of the best drivers in the world to give our customers a vehicle that they can confidently drive in most conditions.  With the extensive list of adjustments and improvements, it is easier than ever to tune the vehicle to your driving style and track conditions. NT48.3 New Features:New revised chassisNew clamping spring perches with captured shock bootsNew rear hubsNew trailing front spindles and spindle carriersNew V2 hinge pin braces and
