While the standard BMW M235i develops 320 HP and goes from 0 to 100 km/h in only 4.4 seconds, many owners don’t find that to be enough. There are many tuning companies such as Dinan that can help you customize your car to your personal preferences.
Dinan presented the “S3†power kit which can take the M235i to 445 HP and 455 lb-ft of torque, therefore making it more powerful than the BMW M2 for less money.
According to Dinan, their S3 kit combines a “Stage 4†plug-in tuning system, free-flowing stainless steel exhaust system, carbon fiber cold air intake, and a dual core intercooler.
Besides that, uprated sway bars and both front and rear springs are also included. They lower the vehicle and make it more stable, increasing the suspension stiffness for 10-15%.
