A humbling experience here but a full bolt on Nissan GTR is no slouch. Neither is a BMW N54 with the Pure Stage 2 turbo upgrade. The E60 chassis is a bit heavier than your typical N54 and namely an E82 1-Series variant.

Run what you brung though. This E60 belongs to BimmerBoost member @viperware and it is a strong car. His vehicle is a 2010 E60 535i with FBO, JB4, Port Injection, Pure Stage 2, RB Inlets, VTT outlets, and an MFactory LSD.

It just wasn't enough.
