Isn't that a forum members car.....albeit he has Morr Alloys on....aka Dubseads? Think he's changed he's wheels a number of times. Agreed that wheels don't suit z4s.....too much vudub dubbing going on....
There is nothing wrong with his suspension, it's sitting on a set of Boadway static coilovers which yes, are incredibly low, but are also designed to have decent travel for the size (not to mention also being valved correctly vs just changing springs on factory dampers).
Wheels are subject to a lot of hate...but it's different.
When he sported a set of ACS Type 2 racing wheels...
Personal taste i guess but BBS RS splits with custom deep dishes are definitely the holly grail for a lot of german car owners. very light, super strong wheels that perform extremely well. Can be a re-mortgage though.... very expensive indeed.
