In addition to increased horsepower and torque, the S2 also features the Stage 3 Suspension System which includes front Springs, Camber Plates, Koni Shocks and larger antiroll bars. More aggressive drivers will enjoy the car’s more neutral balance, with the camber plates further reducing understeer for turn in that is razor sharp.
BMW’s award winning N54 engine is the key engine in Dinan’s efforts to improve the performance for the popular135i and 335i models. The tuned up N54 engine raises the performance to a maximum of 398 hp and 429 lb-ft of torque.
This further increase in power is generated through the addition of a highly efficient intercooler that is nearly twice the size of the stock unit, featuring ducting designed to optimize air flow. The improved thermal efficiency also reduces the effects of increased boost pressure on the stock turbochargers for greater reliability.
