#More_Tuning
So I did all of these:
And it was a night/day difference.
First off, Huge shout out to @bboybowzer, who mailed me not 2 but 3 sets of basically brand new shock blocks, and is now ignoring my asks for his paypal address (pretty sure) because he continues to be 
(still happy to at least send you beer/coffee/boba money brother, youâre too kind)
- De-wedge & wedge the Bro
Decided to go full bore and throw wedges on both sides. CADâed up some quick wedges and printed one of each in PETG with a ton of vertical perimeters for good measure.
Files are available here: Printables: Matrix II Truck 5 Degree Wedge
I realized after starting the install, that these outpaced the truck mounting bolts I had. Theyâre relatively thin - only 2mm at the thinnest point, but 5deg is enough to need +7mm on the thick side.I started shopping around for some M5 x 45 flathead, hex drive, zinc-plated alloy steel bolts⌠might as well be trying to buy a moon rock. Doesnât exist unless I want to pay the McMaster gods their voodoo shipping money.
Then I realized thatâs almost 2 inches of truck bolt - a little long for comfort. Much better to reduce the rubber spacer on the Matrix IIs and save the money for future esk8 parts. So I CADâed up a new half-height spacer and printed two in 100% infill TPU.
(Wedging is confusing, like MBS binding orientation. Bro tips are 30degrees. I want a lower pivot angle on the rear for less leverage / more stability / less turn, and a higher angle on the front for more turn / more agility.)
- New Shock Blocks
The old reds I had on there were noticeable shorter & fatter than the new ones. The oranges less so, but still. Replaced all four.
Wild.
I love the bottom graphic of the Haero Bro. We donât get to see it enough 
New blocks! Still red rear, orange front. Gave them all 1-2mm of preload for good measure, with loctite on the bolts, and took it for a spin. Rides noticeable more stable! Much less tightrope-walking at high 20s and low 30s (mph). Big fan of these changes. And with bindings, I bet if I threw myself over hard enough, I could do a full 180 in one lane of the road. 1.5 lanes is relatively easy.
- 150x50 Sunmates
I did not fully comprehend how small the sunmates are next to the 200 Clevers Iâve been rocking for the last year.
Zero clearance lol. I need to remember I canât drive over everything monster-truck style with these.
Looks ridiculous, but I love the way the tires sit on these Fivestars. I need to build a true street-only carver on small pneumatics asap.
Too bad theyâre wobbly as fuck. As in, the whole board starts vibrating once you hit ~25mph. It easy to see just by spinning the front wheels. Iâve gotta add weights or slime or both. Still, the quick test run was super fun. They feel much more planted, more direct - you feel all the cracks in the road, but (maybe my imagination) it feels like thereâs less sidewall flex, less gooey disconnect. Even at low(er) speeds, it was really fun to rip around the neighborhood.
I definitely need to build a carver for the gokart track.
In other news, still troubleshooting my lazy DAVEGA problems - Davega problems or questions - #320 by sleepless. VESC connection drop offs under throttle all the time. Super annoying to not really know how fast Iâm going.
Also had a balance wire snap on one of my NESE packs and I didnât notice until I tried to charge. Almost had a heart attack when I plugged the charger in and the LLT BMS cell values were all over the place. Just about tossed the pack out the back door in a fit of adrenaline. Luckily an easy fix, but damn. Itâs not real until it gets real.
