And what are the sizes of the 4wd tires? Also, is that measurement when they are mounted? As mounting 4wd tires on 2wd wheels will definitely pull them in a bit, right?

44.45mm is wide. I can measure mine tonight, but I doubt it is wider than that.

I have a set of 4wd front Electrons mounted on 22-4 front rims that measure 33.5mm. In looking at the rules it doesn't even distinguish between front and rear tire so width-wise just about any tire is okay for the front.

The main problem used to be that the cars have to fit in the "box" at roar races. The 4wd fronts made the car a tad to wide for it.

So I'm finally starting to string together a few minutes of laps (in practice with traffic) without being upside down or stuck. What I'm struggling with is corner entry.

Car is box stock (shock oil, springs, camber/caster/toe, 24mm ride height. 8MM [2 skinny shims) battery from back, new Dirt Webs). It feels really good most of the time except mid and low speed corners. I check settings every run.

I understeer quite a bit. My Reedy 800z is currently on the defaults which means 0% drag brake. I noticed adding some braking force into the corner helps tremendously but it's difficult to modulate. I end up pointing the wrong way a bit. I've calibrated my transmitter (Airtronics MX-V) and ESC, brake EPA is 100%.

Will upping the drag brake to 5% (next setting up from 0) help me get some weight on the nose into a corner?

I've personally noticed drag brake helps me. I'm at 15% currently (though I'm using a new motor and it brakes much less than my last). I also have my max brake at 50% so I can really mash the brakes when I need that front bite. When I had it at 75% I noticed I was spinning too much and couldn't control it as much.

Hope a more experienced driver can help you out better but those are my experiences.

Thanks! That'll get me started and suggests I'm on the right track. I noticed Reedy has a couple setup sheets for the 800z. I also ran through the manual again and did some reading. I think I'll add 5% drag, adjust my brake EPA down, and see how it does after a few runs.

Thanks again!

If you are running stock, anything in the reedy 17.5 should be a good overall motor for you.

Those are good suggestions - I'd also look at going to -1.5 degree camber on the front or 1 step softer front spring.

Like someone already said the reedy motors are great, I would probably go with the Short stack 17.5 reedy (1s) or the SchuurSpeed Motors are awesome! I think the SchuurSpeed is a faster motor, and they are within a few dollars of each other.

Well if your car wont fit in the box because of front tires you have issues as 2wd buggy front tires have a way narrower track than the rear, do you have rear tires up front?

People have been using the 4wd front tire trick since I started like 10 years ago, I haven't ever seen a buggy with 4wd fronts fail tech.

Thanks Bruce!

I went up to -2deg on the front. It felt a little bit better, but the car still wasn't turning in all that well. I went back to stock settings until I could figure something else out.

Springs and oil were up next, but I wanted to take the stock setup as far as it would go before I ended up with a mess. The other B5Ms at the track are running mismatched front and rear springs (heavier rear versus front) as well as shock oil weights. So you're on to something for sure.

I'll go back out next week (hopefully) and see how the drag brake and EPA adjustments do. If I like those, I'll probably start looking at buying a couple different shock sets and oils.

EDIT: Ohh, forgot to mention. On March 26th I did a Sporstman class race. There is a AE sponsored (not pro) driver at the track who I chatted with about basic stuff. He really sorted me out on some things. Who knew hitting everything on the way around the track would knock our camber adjustments all out of whack? Anyway, he watched me drive a bit, gave me some pointers, and pulled out the 1MM ball stud washers from the rear leaving me with just the 2MM (instructions say install both). Can't say that did much, but minute changes are probably lost on me at the moment.

I am currently passing on anything 3d printed. I just dont think the tech or the materials are there yet.
