There are many different brands when it comes to parts, generally you get OEM parts which are genuine manaufacterer parts, you can get high quality non OEM parts which are generally to the same standard of quality as OEM parts and you also get budget parts which are cheaper but can be good and make no difference on certain items. We usually supply and recomend our customers high quality non OEM parts, we do not recommend budget parts.
However we are happy to use parts which the customer prefers. On certain items we will never use budget parts such as injectors or turbos. On certain items we will use budget parts if the customer asks such as tyres. We are happy to giude on an individual basis depending on car age, customer budget and car make.
