    Riva S3 vs ET 127

    Has anybody ever done a comparison between the Riva S3 wheel and the ET 127 wheel? Just curious about boost difference and performance. Which one give better top end.

    Anyone know what are the specs on the ET?
    I would not think top end or boost would be much different.
    What is the thickness of spacer?
    Your only going to be able to go so far
    With 127mm wheel. Imo.
    If your splitting hairs and talking tenths then there be a difference.
    What difference did you guys see with in S3 and c wheel?

    So it's about 1/2 pound more boost than the S3.
