STM 11" Secondary on M8

[AKpow]

Any one runnin the Surpeme Tool Secondary on their M8. I am looking at getting one and I am wondering if I should go with the 10.6" or the 11". Does the 11" really drop right in? did you have to change the gearing in the DD. I ride 0' to 5,000' and I am looking for a baseline to start with on the Helix and Spring. the sled is all stock. right now i run a 46/36 with an orange AC spring. Thanks in advance.

clutch it as if it is a pre-DD cat roller, after all, thats basically what it is. I would start with a cat green spring, and strait 53*. it will be a good starting point

I would run a 11" set up. Should drop right in. On my M7, STM actually set it up for me. I'm running a 50-40 helix in Michigan and they set me up with a 45-35 helix for when I'm out west. Also if your going between sea-level and out west I would look into doing there supertip cam arms (so adjustable). In my opinion it is the single largest improvment made to a stock or modded m sled with a DD. There set up puts 10hp more to the ground over the stock set up on a track dyno.
