Just a heads up. I got these in today and they are NOT the right thing.

I do this 3 to 4 times, then I install diff into car. I will do final setting by holding both rear tires by hand and doing a quick 1 second full throttle squeeze. I look for the front to come off the table about 2 inches. I also try to listen if diff or slipper make noise and adjust accordingly until everything is set where I want it. When I get to the track I will do a few blasts down the front stretch to make sure it is all ok. Then I go race
Thanks, I always break in my ball diffs with a drill. I chuck one side right in the drill and hold the gear in my hand. I start where the gear just starts to turn when spinning the outdrives, then progress in about 1/8-1/4 turn increments.

Looks like Carson Wernimont officially joined Yokomo today. We all know he's been driving Shin's cars for a few month but now it looks like there's a contract in place. Source is Lee Martin's Facebook page.

It'll be nice to have a top tier American running the YZ-2 on clay tracks throughout the U.S. Look forward to seeing what he does at the Reedy Race here on clay after running with Shin, Lee Martin, and Tom Cockerill at Worlds.

My T5m doesn't deserve machined pistons!!!!! LOL I just wanted to go a step better than "2" for now, I haven't even had the car on turf yet. Slipper lockouts should be at my LHS Friday, and it's game on for Sunday!!!

Yep but only had clay tires and needed ss. I will return when they have a big race. Extreme hobbies and wildflower are both within 10 minutes from my house.

Hey Aaron. I was born in Chattanooga Tennessee All is good. So that explains your non presents around here. Wish I could pick up like that and leave this over priced area. Any how the yz2 is a great choice. Wish you all the luck and fun.

I took my YZ-2 out to the Outback Raceway at Amain this morning for it's first outing. I started the day with my B5M Lite and ran about 20-25 laps with that car before switching to the YZ-2. On the second lap with the YZ I was within .3 of a second of my fastest lap with the B5M. I built my YZ to STLNLNST's setup with the exception of using Associated oil and the kit pistons. The car felt good but maybe a bit soft for Outback. It definitely was a bit edgier than my Associated. I feel confident that with some more time I can have the car dialed. I'm looking forward to seeing how it works at LSR.

I might be "thick" or something, but I'm not understanding the options on the set-up sheet for the rear hinge-pin holder spacers. I beleive the manual has you inserting both spacers under the hinge pin holders, but the set-up sheet shows an option for above the hinge pin (on the rear-rear). Is that even possible, or am I reading into this wrong?

What does putting the spacer above the rear-rear holder do? Maybe change angle of gearbox? when would you use it?

You found out the little secret hehe those spacers are actually for roll center.

No spacers is a low roll center
Spacers installed is a high roll center
