Chassis Tuning with the 3Racing FGX-101A on FGX EVO

For racers focused on setup consistency, the 3Racing FGX-101A Fiber Upper Arm Stiffener reduces upper arm flex that can mask suspension tuning. Fitting this part tightens arm stiffness so changes to shock damping and anti roll balances become more predictable.

Material Properties and Performance Impact

The 3Racing FGX-101A Fiber Upper Arm Stiffener employs a high strength fiber laminate selected for a high stiffness to weight ratio. The result is reduced elastic deformation under load, improved steering precision and more stable camber behavior during lateral loads.

Fitment, Installation and Setup Advice

Installation aligns with FGX EVO mounting points and is intended for straightforward fitting during a setup session. After installation, recheck alignment and perform incremental adjustments to shock compression and anti roll to capitalise on the reduced arm compliance.

How does the stiffener change roll characteristics?

By reducing upper arm flex the chassis shifts roll distribution slightly; expect crisper roll onset and a marginal reduction in overall body roll. Tune anti roll rates and damping to restore desired balance.

Will camber behaviour be more consistent?

Yes, the stiffer arm support keeps hub geometry more stable under load, which helps maintain target camber angles through cornering for more repeatable tyre contact.

Any special installation torque or hardware notes?

Use the original FGX EVO fasteners unless otherwise specified. Apply moderate torque and a thread locker if the car sees high vibration. Verify no binding occurs through full suspension travel.
