Ran my very first high grip Astro race today. I wasn't sure what to expect as I've been racing on ozite carpet so far this winter (and some med-high grip clay). While carpet has a ton of traction, we are required to use smoothie tires so it feels and acts a lot like high grip clay. The Astro, on the other hand was out of control grip. I only got a few laps of practice but quickly made a LOT of changes and ended up with a pretty darn good feeling car. I know I can make the car even better with more changes that I'd like to make/change but for my first time ever, it was really good.

Now I have to switch back to the setup I was working on for the carpet for next week. I'm wondering what kinds of things some of you guys have tried on the '16 model. I was running 10k/10k 0.5mm slipper but I'm thinking of going slightly thinner out back (7K?) and maybe up a little in front along with the thicker oils I ran today.

Anyway, any thoughts for those of you that might have a little more time on the car would be appreciated. I am hoping the medium plastics for the chassis may arrive in this shipment with the XB2 cars, which I'm also anxious to try out!

Try the yatabe setup. Go with 15k front and 10k rear. Four dot front spring and 3 dot rear spring. I run 50w front and 45w rear losi oil. I can push my car very hard on high bite carpet.

I'm sure this has been asked before but has anyone tried the ball diff [XRA365000] on dirt?

I was a lot of the way there. I need longer ball studs to run 6mm spacers under the rear hub ball stud and I ran out of time to put the correct pills in. Yes, I realize the pill thing is HUGE for Astro but when I put the stock hexes on to run my astro tires (I glued them to the stock 14mm wheels), something was binding. I spent way too much time shimming, etc only to realize the OEM set screws on the aluminum rear hubs stick out far enough where they aren't compatible with the stock hexes. Go figure. That fixed, it was midnight and I had to get up at 6am to make it to the track.

I believe the Yatabe oil would be TLR 60wt front, 45wt rear. I had 60/40. Anyway, will get more ballstuds, will put correct pills in, and will get 45wt for the back, and will get 15,000 in the front for my next race there.

I have to say, I am faster with my XB4 than I was with the TLR 22-4 I've been running since it came out. I just love this car - it responds to setup changes and is pretty easy to drive. I can't wait to race carpet next week, I can't wait to race Astro next time... I can't wait to race the XB2 either.

Oh, and anyone have the servo arm hitting the body when you installed the floating servo mount? Didn't hit with the stock mounts, does with the floating mounts. Darn it! Also, both the stock and floating mounts seem really wide for the servo. Never run into that before.

No. The center diff is a gear diff only.

Works great in combination with the center slipper on loose low grip tracks

Take a look at Malin's Yatabe setup for the '16 and basic high grip astro setup for the '15.

Both setups are dialed for smooth and bumpy astro respectively

This sounds like exactly what I need to do. My bro just got a YZ4 and I had the previous fast lap of 15.4 which was .2 seconds faster than anyone else. Well, he spent some time dialing in his car using my old 15 caster blocks of my bmax and going up in shock oils and up in the front diff. He was able to rip a 15.2 which was .5 seconds faster than he had gone before.
My car is great, drives awesome but I can't get a 15.2, I tried running 110% with the the setup, i hit my line perfectly but it isn't gonna happen. If I sauce my tires heavily I can definitely get more corner speed but the car will traction rolling. I just ordered the Yatabe 16 setup parts.

The offset are the same as X-ray XB4 wheels, fortunately. This is great if you are using 60mm or 2.4 wheels. You can see what hex the team uses a few pages back in BentKa's post about offsets - +0.75mm front and +1.5mm in back.

If not mistaken get the 9mm rear exo1408blk to get close offset in front.

You want the 5.75mm and 6.5mm 12mm hex measured with the flange. Thin one up front and thick one out back.
