Explaining the new features
New XLi superlight 2-speed gearbox
The XLi gearbox comes from the Viper 977-Evo kit and is well proven for performance and durability, as well as ease of setting. The lower inertia will make you accellerate faster.

New aluminium middle bearing blocks ( holding brake and 2-speed)
To hold the new 2-speed gearbox/shaft as well as the existing double brake system newly designed superlight alumnium bearingblocks are designed.

New front front and front rear aluminium suspension holders
These are designed to change the piviot pin angle, so the lower wishbones will be more straight, which geomery suits onroad racing better.

New Alu c-hubs in 6 degree version
The new alu c-hubs are needed to make maximum use of the new pivit pin / wishbone angle.  CNC-machined from 7075 T6 alumnium, laser engraved  and black anodised units.

New aluminium, uprights for new rear geometry
To allow a better onorad geometry we desigend these new CNC machined aluminium uprights, black anodised and laser engraved.

New alu shockabsorber risers front and rear
New alu shocktowers front and rear
The durable machined alu shock-risers front and rear allow for a more onroad aimed angle of the shockabsorber creating more overall grip and more predictable cornering.  The new 4.5mm lower carbon fibre shocktowers also accomodate the new shock angles, with a choice of 5 holes for further fine-tuning.

Chassis stiffners  
Composite  stiffner front and rear, to give extra stiffness, but still allow some flex as needed.  
   
Central diskbrake  system  
Very low and centrally placed brake system for low centre of gravity with ventilated glassfibre brake disks, combined with thick steel plates which wont bend under pressure.    
   
Radio-box    
Composite radiobox which offers space for the lay-down steering servo and  the upright placed brake-throttle servo. Sufficient spacers are supplied for correct fitting of the servo’s.  The receiver and battery can be placed safely under the large cap. The transponder can be mounted in the central part, between servo and receiverbox.  The whole assembly including linkages can be taken off easily and fast in one go, when cleaning the car, or doing maintenance.    
   
Servo arms and linkages  
The servo arms have a splined insert to have the right fit per brand. The linkages runs very clean and tight and are easy to access to modify settings.  
   
Suspension brackets  
Beautifully machined  7075 T6  suspension brackets in anodized, laser angraved. Pecision fit for the nylon roll center inserts  and pivot balls / pins.  The GT 3.0 front suspension brackets make the pivot-pin and lower arm more horizontal, which improves handling and steering.  
   
Steeringblocks assembly    
Composite steeringblocks combined with alu 6 dgr C-hubs  for precise steering. Spring steel wheel-axles with large size bearings 8x18x5 and 15x21x4       with precision threaded aluminum wheel-hubs with +3 offset  . Flanged wheel nuts to guarantee that you will not loose a wheel nut in a race.  
   
Front suspension  
Durable oversized  lower suspension arms in strong composite nylon. On the lower side the special downstops screws are mounted. The lower shock-mounting pins are secured with a small grubscrew from the bottom.    
   
Front anti-roll bar  
The ballraced front anti-roll bar  system, consist of a spring steel bend wire, which is guided through the diff-cases and run in ballraced steel adaptors.  The wire is linked to the lower suspension arm, with a captured adjustable threaded pivotball, for very precise and low friction  operation.  
   
Shocktower and bodymounts front   / alu shock-risers
new 4.5mm thick carbon shocktower with 5 upper positioning holes for the shocks and and 6 holes for roll-center positions.  1 centrally located adjustable bodymount , and 2 forward mounted adjustable bodymounts, all with flip-tops.    The durable machined alu shock-risers in front allow for a more onroad aimed angle of the shockabsorber creating more overall grip and more predictable cornering.    
   
Angled steering system / servo saver  
The bell cranks are angled to reduce the angle of difference between the total caster and steering plane. Therefore you will have less bump steer and a truer steering Ackerman through the entire range of suspension  
   
Ackermann plates  
With the design of the steering bell cranks when changing the Ackermann you will not need to adjust your steering tie rods. You simply will only need to adjust your end points on your radio..
