But you cant compare the two when the oils and piston holes are not the same. now if you tell me that you have 8 hole pistons and 30wt on both sets of shocks then i would take the test more serious. And like Shaun just said dropping your truck 3' is a motion that will never be replicated on the track so really means nothing. Changing anti squat will effect that test, front kickup and shock positions make differences also. landing with your finger on the throttle can also make a difference versus not.
Comparing stock B4 shocks to the new 12mm shocks and then thinking that going from 13mm to 16mm is going to make the same difference is skewed too! 10mm shocks were and have always been undersized from the get go so of course when you put a proper sized shock on a B4 its going to make a huge difference but the 13mm SC10 shocks are not undersized. If that were the case then the next step in 1/8 scale would be 18mm! it has been proven that even 17mm is borderline too much on an E buggy so 16mm on a super light weight truck is overkill. They will work and i am sure that in some situations may even thrive. Think about what you are actually doing, no matter what size your shocks the oil has to flow through the piston holes. The SC10 shocks have a pretty good amount of volume to them compared to most and we all know they work very well. Just food for thought before everyone goes out and buys 16mm shocks.

BTW UFO pistons are in the final stage for 12mm, pre-order starts next week. SC10 4x4 sets will be ready in three weeks or so. I havent said too much about them but I have been doing LOTS AND LOTS of testing so that they will be perfect. In a nutshell (more will be explained on the video) the thinner the piston the faster oil flows through the holes and vice versa. UFO pistons are thick and utilize 2 large holes ( but are spot drilled for 3 and 4 hole options). The results are a piston that allows the use of light fluids but give a "super pack" on hard landings and a plush pack for the med/small jumps and obstacles. Rebound is slightly faster by design since the pack is dynamically increased. Basically a piston that is tailored for the indoor hard fast track crowd!! Driving impressions have been great, the plush pack is most notable on jumps where you have to land and immediately turn and rhythm sections. They dont jump as high or far as 2 stage but sometimes I have found that on large jumps i tend to over jump with the 2 stage since the rebound is so much quicker.

Another major plus is that these piston cut down shaft stiction DRAMATICALLY!! since the pistons are thick and have two contact points this keeps the shaft straight and pressure off of the orings resulting in a better seal, less shaft wear (nitride wearing off) and overall smoother action. Normal pistons only have the piston contact point and the oring so as your shocks go up in travel pressure is put on the upside of the shaft...not anymore!!
