My car is heavier with brass rear ballstud mount, smc brass rear weights, front brass arm mount.

Car bottoms in the rear very bad.

Anyone use vrp pistons? If so which ones?
What brand/style of 1.6's are you running ? Square edge ...taper ? Also your front end set-up seems stiff to me making the rear slap harder.

I got 1.5mm on each arm, so 3mm in total track width increase.

I should have taken a pic when I was doing the conversion, as I didn't quite believe it too.

When you use the 5mm hexes (as that is recommended) its only .5mm per side. If you use the 6mm hexes yes it would be 1.5mm per side.

I'm using the flat machined yokomo pistons. I've tried softer front setups but the rear still bottoms hard. Using the bmax 4iii longer arms and longer driveshafts as well. Maybe I need to increase rear droop.

Try adding 2mm of spacer and an oring on the outside of the shock shaft. There is a little over up travel on the shocks and these spacers seem to help me with issues like this.

Theoretically more consistency/"smoother". However, if you run stock, the last thing you'd want to do is add more rotating mass. If you run mod and you're doing so with this car, that means you're already probably racing on a surface so grippy to the point where your slipper is being used more to save the idler gears on jump landings than to actually slip anyway.

I run on astroturf exclusively...wondering if this is even worth looking into to further stop traction rolling?
What's the rest of your setup? I only race astro with an occasional carpet race thrown in and the YZ-2 will be the absolute last car to start traction rolling anywhere.

Little more droop and maybe some rebound ? I'm running stock arms and about 30% rebound .....also running ae pistons ....

looks nice, thankfully all of my local tracks are medium high to high bite, so I lock the stock slipper and am on my merry way

Agreed, he needs to pack up the whole car running all of that weight in it. How much does the car weigh? My car mostly stock slaps from time to time, but nothing that really gets it out of shape.

How do you get proper rebound with emoltion shocks. I thought they had to be bled completely Bladder shocks can achieve rebound.

I will try to get some pics up tomorrow.

I'm sure it was 1.5mm each side, just comparing the arms alone! I had them one on top of the other and it looked around 1.5mm longer.

hmmm got me stumped now
