Had my DC5 for 6mths, however the vin plate says Type iS rather than Type R. Is this a base model ? Most parts have been added since entering the UK. I do have recaros,momo wheel, quaiffe lsd, Spoon exhaust and skunk2 suspension. The paintwork is pearl white which is same shade as championship but with pearlescent through it? I have an ecu fault due to oxygen sensors can anyone help??
