The new Avid springs are going to put all of the miss matched, incorrectly labeled springs to rest. One of the local AE drivers is already running them, and he says they are way better than the TLR BB springs he was running (which he said were way better than the AE standard bore springs). This guy is a personal friend, not just somebody plugging a new product, so I really believe what he says. He also happened to get 3rd at the Reedy race in 4wd, so he is no slouch behind the wheel. I wouldn't be surprized if AE uses the Avid springs on their new BB shocks as standard. Kurt Wenger is the man behind Avids new 1/10th scale products, and as most of you know he was working for AE before his move to Avid.
