Team Associated RC8B4 Factory Team RWB Chassis | CompetitionX

Team Associated has come out with the Factory Team RWB chassis for your RC8B4. This new designation – RWB – stands for Rear Weight Bias, and shifts the major components on your RC8B4 rearward to reduce the amount of weight on the front tires, increasing rear grip.

Quick Stats
Product: Team Associated RC8B4 Factory Team RWB Chassis
Part #: 81589

Price: $106.24
Build Type: n/a
BUY NOW: https://bit.ly/3ARLDFl

Features
• Durable CNC machined 3mm 7075 aluminum with hard anodized finish and laser etching.
• RWB = Rear Weight Bias. Shifts engine, tank, center differential, and radio tray rearward 10mm.
• Increases rear grip in low traction.
• Improves predictability on rough track conditions.
• Increases rear chassis stiffness.
• Installation supplement included.
• Required (not included): #81580 front and #81581 rear center bones, #81592 RWB radio tray brace or #81433 servo spacers.
• Fits: RC8B4 nitro buggy.

What We Like:
This is the same chassis setup used by Spencer Rivkin to take the win at the 2023 TNR Challenge, so we know there’s some validity to this setup. Just the idea that this chassis tones down the car on low grip or rough tracks will make this a very popular choice for 1/8 scale racers.

What We’re Not Sure About:
The chassis is not the only thing you need to buy. It would probably be a better selling upgrade if everything you needed was in one package.
