What are the specs on the R34 GTR wheels?

GTR 34 rims : 18 x 9 J offset 30

I found the offset to be a bit too little for the GTR 33 and even the GTR 34 but fits perfectly for the GTR 32. You would need something like an offset 12 or 15 for a 9J rim in the GTR33 and GTR34. Frankly , I think the the GTR34 stock rims are the best looking stock rims that you could get. and on top of that, inspite of them being 18"s, they are the lightest out of all the other GTR variants !!
