I haven't driven it that much to really answer your question as accurately as possible, but I can tell you that the difference in weight between the stock BBS and Konig Hypergrams is dramatic! I assume that the weight reduction would result in faster acceleration, or less work to spin the wheels. (Note that I'm a cyclist and have a basic understanding or rotational mass, but I'm not a physicist either.) The ride does feel more comfy with the bigger tires, but my coilovers are on the stiffest dampening setting. There are a couple of threads on here that talk about switching to 17s, or a track setup. Check them out:

These two were very helpful in determining the best 17" setup for my Z4.
Thanks! |
Hello, Adolfo!
Did you use camber plates? Are they necessary for this setup? Any rubbing issues on front?
Currently I have 245/35R18 by 18x8 ET 40 square. I want to go with 255/35R18 on 18x9 ET40 square.
