Special Product Notes
Product Description
Dinan lowers the stock 3.85 final drive ratio to a 4.10, taking full advantage of torque multiplication for a substantial 6.5% increase in torque delivered to the road. The improved acceleration comes with only a minor increase in engine speeds at cruise and no effective reduction in top speed potential. The Dinan 4.10 Limited Slip Differential delivers what is perhaps the greatest bang for the buck in terms of improved and more immediate acceleration from the M3."
