Advan RG-D does come in black, but this one definitely a replica set.

Look at the ADVAN Racing wording.. the spacing is not even.

This one is original:


Also, the owner is using cheap tires. If the rims are original, at least must match with good tires lah.. these are the sort of tell-tale signs.

A lot of replica nowadays very close to the original. JIL or JAWA stickers can be sticked on no problem.

The only thing they cannot do is to emboss or engrave 'Made in JAPAN'.. because they can get sued if they do so they can only put 'JAPAN', or 'Design in JAPAN'
