First of all, Mr. baviaria performance....
.... you should stick to the truth!!!!
your rims arenīt the M359 OEM -> so itīs nothing special that these rims matt black
(WHAAAAT????)
to run a 135i with 420hp youīll need a little bit more than a chiptuning and racing pre-cats! follow alpinas example-> the B3S with 400hp!! you need different turbochargers, a bigger intercooler and an additional watercooler (like the PP-package)! the thermal load without changing these parts is enormous
