I actually have a 17.5. Its not a schurrspeed or whatever its called. Just a Gen 2 tekin. But smac is a super long day and when I get home at 5 is when me and my son get to rebuild our toys together! He's 3 and can already keep his losi 22 short course truck between the pipes! Next year I might take him up there and make a day out of it, but right now his attention span is a little short hahaha

You can probably use the front / rear aluminum holder but it is a snug fit. In the rear / rear you will need to use the kit supplied plastic mid rear holder until you get the new aluminum holders f/r & R/r.
The old rear/rear holders will not work with mid-motor configuration and if you go to rear / rear new aluminum holder you will have to get the f/r aluminum holder as well to adjust the toe properly.

I am at work currently, but I run on high bite carpet. Pretty much andy dibrino's setup but with 35wt losi oil/yellow springs 4x1.3 pistons in the front, 30wt losi oil/red springs 4x1.3 pistons in the rear. The rb6 rear arms/long shock eyelets (only because my rb5 arm broke the week prior). Mid motor. 1/2 oz of weight on rear bulkhead. 8.5 tekin. Schumacher mini pins blue compound. Ill just make a setup sheet and post it here.

RE: Kyosho V2 0 Aluminum Rear Hub Carrier Set KYOUMW704-0
I'm having a difficult time understanding which bearing combination to use. Is the "5x13/5x11mm axle bearing configuration" saying that the outside bearing is 5x13x4 and the inside is 5x11x4? Looking at the plastic inserts, there only appears to be one insert small enough to fit on the inside of the hub. The other three look like they only fit on the outside. Please explain so I can purchase the correct size bearings. Thanks.

I went with 5x13 but have 5x11 as backup
