Following hot on the heels of their previous aluminum parts release from yesterday JConcepts is now offering three of their RC10B7 parts in a heavier steel. Each of these parts can be used in conjunction with other JConcepts weighted pieces to tailor your car’s handling for any track surface.
First out of the gate is a new steel front bulkhead weighing 25g and is offering both a zero degree and 2.5 degree kickup option (each sold separately). Coated in a durable black oxide finish these steel pieces look the part with the performance to back it up.
Need to balance your rear weight bias to match the front? JConcepts has you covered there too with their new steel C and D blocks, Each of these black oxide coated pieces are precisely machined to accept the stock AE suspension pills. The C block weighs in at 15.3g and are offered as a -1 degree toe-in mount for added adjustment not available with the stock parts. Coming in at 9.2g the D block matches the stock geometry meaning all of the suspension settings outlined in the manual can be attained with ease.
