Geeko indeed. Really interested to see if they live up to the hype. Highly likely that Nitro (and you) make better turns @b0ardski , but as long as they make my turns better I'll be happy. If they don"t, I can always use them to get a job as a high- rise window washer ?
For comparison on stack height, my TD3s on the std 3 deg cant bases are 1.75 inches to top of toe block, so the Geckos + BP lowers are only adding 0.25 inch overall. Pretty reasonable.
And my suggestion to ditch the BP elastomer was a bit misinformed - you would need to face off the center ring to take out the end float.
