RX8 Xray – 2018 Specs – 1/8 Luxury Nitro ON-ROAD CAR

All-new 2018:

• All-new chassis features larger front window opening for improved forward traction
• All-new chassis with unique, innovative front flex adjustment using a removable aluminum brace. Using the aluminum brace increases steering response and cornering speed; without the aluminum brace, the car is easier to drive.
• All-new adjustable weight position on both sides of the chassis for quick & easy weight balance adjustment
• All-new rear layshaft bulkheads allow use of bracket bushings to connect the layshaft bulkheads with rear bulkheads to reinforce the entire rear suspension, giving improved handling especially in high-traction conditions.  Without the bracket bushings, the car has more traction; recommended for low-traction conditions. The new bulkhead design also allows installation of a top graphite brace.
• All-new rear aluminum bulkheads
• All-new graphite brace for rear layshaft is part of the rear suspension Multi-Flex™ Technology
• All-new graphite holders for rear upper arm have new positions – lower & more inside – for increased traction and improved durability
• All-new rear aluminum suspension holders have new position for the rear arms – more inside – for increased traction
• All-new steel extensions for suspension arms have a new position to work better with new rear aluminum suspension holders
