Chassis is still alloy but you do get a hand full of option parts worth over £120

Titanium Turn Buckle Set (B4-TBS)

Graphite Center Mount Plate (B4-304MG)

Titanium coat shock shaft (B2-S2S & B2-S2L)

Aluminum Shock Cap Ball (YS-8BH)

Graphite Center Link Support (B4-200SS) This is the only part that you would want as it stops the steering assembly from flexing

Aluminum Rear Hub Carrier 0° (B4-415R00)

Everything else is just cosmetic go for the cheaper kit and spend the extra £7 on B4-200SS
