Well that is certainly what I am hoping. I just got this information from the manual on page 15 where it shows the "A" and "B" configurations

Bummer.. getting it turned around is no big deal but I just hope I can shim it correctly. I've never done that before

Just picked up a used one, looking for wheels but which front wheels fit? The only 'zx-6' specific wheels I can find are from Kyosho...do the RB6, B6, or 22-4 front wheels from jconcepts/pro-line fit?

Thanks!

All I've used were the stock front wheels, AKA (they are re listed as being Kyosho specific in both Evo and hexilite), mostly.
I have some PL ones so they should have some. I think there's others that will work, but I'm not sure of the offset variances between different Mfg.'s, like say, Losi 22-4 and ZX6

Never heard of switching the diffs for Front Motor. Just rotate center diff and shafts and your done.
You do have to swap the diffs crown wheel side over otherwise the car will run backwards.

Yokomo and Schumacher both fit,

Schumacher wheels are softer and gain grip over the Kyosho wheels, my choice on wet astro.

So I was driving the car last night and mind you this is my first 4wd. But it was kind of hard to drive. The car was really loose coming into corners. Like if I let of or coasted into a corner it would sometime completely spin around the rear wheels. do you just have to stay on the gas a little bit to round corners nicely?

chansharp I noticed the same thing w/ my 4wd. I wonder if it is set up related or just how 4wd buggys work? Staying on the guess is the only way for my car to not spin out in certain spots on the track(mainly higher speed turns)

Guys are you running gear difs or ball? If ball the tightness of each dif is very important. Also more aggressive front tires than rear can effect the rear of the car as does the sway bar. What type of surface are you on?

I have ball diffs. And it is true my front tires had more tread than my rear. And always find the "what kind of surface are you on" question hard to answer since it's relative. But I am on clay, usually watered and decent traction. Don't know if I would classify it as high traction.. but

I run gear diffs (8-500-8), front tires wear more then rears, med/high bite clay running treaded tires. I just put a thinner sway bar up front (1.0) 1.3 in rear. I got more steering w/ thinner front sway bar but rear end still wants to come around off power when turning off of fast straight or fast sweeper. Thank you for your time/help likea45

What is the tire of choice at your track? That will give me some indication of what kind of surface it is. While it may seem subjective, it's relative to how you set the car up. I would try running your rear dif a little bit looser and swap your front and rear sway bar.

On treads I found that 500k was just too stiff and anything above 7k in the rear was not letting the car rotate as it should. I had this issue initially at 10-500-10. I tried swapping the front and rear sway bar and then found the magic number (for me any way) which was 7-300-5. Give it a whirl one of the two tracks I run at regularly sounds like the surface you are on.
