YXZ supermoto

That is the sort of video that makes me think side by sides would be slow as berk on a rallycross course.  There are no tight corners at all, the tightest corners they do have feel like watching a supercar trying to navigate an autocross, and they seem to be only hitting 60-70mph in places where, if someone had cars on that course,  the cars would be hitting 100-110.

Is it a gearing thing on the straights?  It seems like its accelerating pretty hard and then the driver just lifts for no reason.

That video is kinda a mixed bag...seems like driver skill is a big factor. The thing definitely sucks on pavement (but that's not exactly a surprise) but a lot of the dirt sections seem to be about the size of a rallycross course and a lot of it looks like it's a fairly loose surface. When the guy isn't surrounded by a gang of slow people or forgetting where the course goes, IMO it actually looks pretty decent most of the time. That and the circle track videos are the first things I've seen that make me actually kinda interested to try rallycross in one.

Yeah, I think that YXZs are gearing limited to around 80 MPH, so for that sort of quarter mile, they'd have had to change the final ratio.

Brianne/Dozeman Miata has interesting stuff, especially on the front wheels.  They were flirting with ftd on day two across all classes at nationals last year.
Doug Liebman's beetle is on something close to an autograss tire but not exactly an autograss tire
Leon used tractor tires in the mud.  He brought studded tires a few years ago (now banned) and is now experimenting with duallies.
I didn't see Vaughn's mud tires.
The rest of the class fell behind once the rain started

Prepared Rear has moved to the Indysport BR as the spec mud tire.  They were worth 30 seconds per run over the next obvious tire Indysport SG/Maxsport RB1F.  It is only going to take one fast driver to spend $2000 on tires to make everyone do it.  All the exotic stuff is still legal.  Someone local found a company that would retread a 17" tire carcass with a rally compound so he could run stock brakes on his STI.  I assume someone is going to build something silly in the future.

The main problem is you guys keep having muddy national events. lol

Vaughn brought all his fancy tires out to Susquehanna last year (dry conditions), tried several of them, and was considerably slower than me (in a heavy stage rally car) and Shawn Roberts (in a PR car) pretty much the entire event, with both of us running old gravels, as I recall.. A couple weeks later he got on the national podium. YMMV. 

In mud events, it's all about who brought all the crazy tires and/or has the really good rear weight bias. That's why Vaughn beat me and England at the 2017 East Coasts (I mean, aside from being a good driver).....the start line was a mud pit and he got a few seconds on both of us out of the hole before the first turn, lol.  He had the tires, and the rear weigh bias (transaxle Porsche). Me and England were just spinning off the line trying to get traction. Once going, it was pretty even times, but can't throw out the start, sadly :)

In dry events, totally different ballgame. 

Just my opinion, as if it matters. We rarely run wet events here, since our venues are all red clay (and no tire works on it when it's totally wet), so dry to dry-ish events are all I really set up my car for. One reason I don't go to nats (that and distance/cost)...it always seems to be muddy. Going slow in the mud isn't fun to me........

Anyhow, I'll stop dragging this off-topic lol. Proceed with SXS discussion.

I pretty much agree.  I wonder if RWD rallycross is going to consolidate to mid/rear engined cars over time.  Now that I don't have family 20 minutes from the nationals site, I am going to wait for it to be somewhere closer or less muddy.  It looks like a 21-22 hour tow to Road America for me and all the sites within a 10 hour tow are clay based and don't match the surfaces in the midwest.

It's coming, at least in stock. Mid engine cars have won the SR championship two of the last three years, and the only reason it wasn't all three is because none of us bothered to go last year. Weight over the rear wheels is even more of an advantage when you're limited on tires.

MR2s are quick (we currently do and previously have had several running locally) but have major problems with dust intake (even running a roof scoop) and some other issues. But even the fast ones driven my fast drivers (fast in different cars) don't usually finish higher than mid-pack in DC's MR group. Chris Nonack was the exception in his V6-swapped 2nd gen - it was very fast but seemed to frequently break.

If I had a lot of money, my rally/rallycross build would be a Cayman, I think. Though I can't say I really know how the suspension setup would hold up, offhand. Just like the idea. And as we've seen, Boxsters can do well. Not sure what other mid/rear engine cars out there would be competitive offhand, at least in the range of "affordable things" for most rallycrossers. I"m still of the opinion that Miata/e30/e36 are the three top cars that can be found affordably, run reliably, and have good aftermarket support for rallycross. I'm not convinced yet that BR-Z is the fourth answer for rallycross (though for stage rally, it's quite good). 

The real kicker is when someone puts an electric motor into a Boxster or MR2 ;)

Honestly the brz is what makes me unconfident about my mental algorithm of what makes a good rwd rallycross car. On paper they're lacking the two main qualifications (torque and rear weight bias) but they've been proven decent in the real world. I'm not sure we're there yet, but I think once they're consistently sub $10k cars it'll be hard to pick anything else as an easy button.

Nothing I don't specifically like about them. I almost bought one as a DD a couple years ago, actually. But yeah, on paper they are exactly what I wanted. Then I drove it and was like.....meh. IDK, just didn't seem as good as it *should be*

I do think that like any newer car, they weigh more than something older. Not that you can't get rid of a lot of that, but not sure BRZs are quite yet in the price where it's worth making them a dedicated car just for rallycross. The ones running stage are a different story, and are for the most part pretty highly-developed. But still, they're not going to get down to Miata weight, and frankly I'm 500lbs lighter than a BRZ with the same power in a M50-swapped e30 (and mine is fully caged, carrying two spares, and all my stage rally gear, so it could get a LOT lighter. If my car was built as a true MR-class rallycross car, I'd be just over 2000lbs with 200+hp. 

I'm just not "convinced" yet because I haven't seen any being particularly competitive in competitive rallycross groups (yet). As they get cheaper and older, I"m quite sure we'll see more of them and see more of them well-developed. 

I also haven't driven one in anger/on course yet, though, so still a bit hesitant about the torque curve of a NA subie engine. I never felt llike my stage 2 WRX had enough :)

That's crazy cheap, even with added expense for a proper roll cage and tires (if needed).  Pretty good power to weight compared to other popular cars.

The dude had it listed at 10, which is already the best deal I've seen anywhere. I threw him an offer of 8. He said, "I need the cash for my business. Come get it". I'm already eyeing the DIY CageWRX kit. The internet says fitment is spot on. I'll be posting updates here: Lof8 Build Thread

with a few mods, this thing should be a rough approximation of a reasonably priced cross kart, which are about $50k

I'm not familiar enough with MR rules to know how what kind of weight loss can be expected.  In STX trim a BRZ is 25xx, which doesn't seem terribly heavy, especially by today's standards.  I'm sure gutted lightweight track car efforts are in the 22xx range.

I've seen several clean, but salvage title cars sub 10k.  I saw one for 7k recently.  Honestly at this point they seem just as easy to find a good candidate as it is to find a E30, possibly easier.

That is because rallycross does not have straights anywhere near that long, so you spend all your time turning.  This is by design, to keep speeds down.

 

I have some footage of an event where we had to simplify the course for logistical reasons and I was shifting into 3rd before the middle of a straight.  I can't really translate wheel speed to vehicle speed but 2nd gear was good to about 70 and 3rd was good to about 110, with the 65cm tires I used to run.  (Assuming 9k rpm.  I have pinned the 10k tach in gear before...)

 

It should be noted that I do not have a fast car.  It is heavy for a 2wd car, and cars its weight in AWD classes have 400hp or more...

 

When I see wide open courses like that video, I think damn, I'm going to be running out of 3rd, and my car is not stable at all over 60mph.    But everyone else is on the same course, so nut up or shut up.

That looks like a fun fast course!  Who knows, maybe I'll regret the change to SXS, but I don't think so. 2 more added bonuses about the Yamaha: my wife and I have been wanting a sxs for a long time to play with out in the woods trails. And there's a dirt track in Ocala that hosts sxs short course wheel to wheel races!
