lol! If you knew the history of the car it doesn't look as bad. This did have a turbo SR20 in it with 18" BBS LM's but if was sold to it's current owner before the project was completed. The lip is "homemade" fiberglass modeled after an e30 m3 EVO III spoiler, just lower and bigger.
Now the car has a S50/S52 from a e36 m3 and the Advan RGII's are only temporary until the owner gets something else. He has a 13" brake kit for it and a few OEM upgrades planned. The "JDM" sticker was a joke to go with the Advans, carbonfiber hood, big lip, and goofy mirrors...
I've seen them with TE37's before so I wouldn't say Japanese tuner style wheels always looking bad on an older German car! lol!
