That tag sounds too broad. I look to the tags to indicate "all of these questions are like the others in the same set." If I clicked the custom tag, what set of questions would I see? Everything about custom bodywork combined with custom audio combined with custom upholstery stitching?
Looking at it another way: which of these are custom?
- I replaced my shocks with OEM equivalents but not identical parts.
- I replaced my axle-back exhaust with a stainless steel equivalent part.
- I retuned my ECU but left all original equipment in place.
- I replaced my up-pipe with a free-er flowing unit.
- I replaced my tires with a different brand of all-weathers.
