The JL8 option is the factory installed 4 wheel discs and includes different front calipers, different brackets, no proportioning valve, rear discs, different e-brake cables, etc. A complete JL8 setup with front and rear components is worth $7-10K depending on how complete and the condition of all the parts. The service package rear disc setup is not a JL8 setup, but very similar rear components. Just the rear service package components should bring around $6-8K.
