Some/ most of the GE8 parts wont fit our GE6 so its best to get clarification.
I originally wanted the J's Racing front lip spoiler and found it wouldnt fit.
Also, Spoon quotes both a GE6 and a GE8 model for the N1 exhaust and I've been told by my N1 supplier that the GE8 N1 is slightly longer than our GE6 so there will be differences
HTH
