Sounds like no more ChaseBays master cylinders, and no more Denofa-esque springy systems. Also, Wheel tethers, probably a good idea after the unfortunate events of last season
Thanks for posting all this.
I'm pretty excited for this years competition. Pro1 and Pro2.
Looking out for Blake Olsen (e92), Danny George (e36), Andy Hateley (e30) in pro 2.
Pro1 I'm mostly excited to see how Ryan Litteral does, and of course Denofa.

Internet rumor has it Denofa will be in a Mustang next season, and his subtle hints on IG seem to agree with that.
Hmmm. I heard rumor a while back (via formula derp) that Gittin was taking him in to form a 2 mustang team. Who knows how accurate this is, but in a recent instgram post he posted a photo of the LS saying "another trusty STEED with about 800whp NA coming soon" So it sounds like he's either going to be driving a mustang or at least have a mustang drivetrain this time around.

I love Bluss and the HGK cars. I think he will be in an E92 this season IIRC. I was about to bring up Wang too, lol. I saw both his cars for sale, so I assume he's done with FD? It also sounded like Alex won't be with Get Nuts anymore based on his interview on Maximum Driftcast a while ago.
I see lots of good stuff here. The wing tethers are absolutely necessary, both Pollock and Kearney had a broken rear wing nearly come through their window last year, and of course it also protects fans and course workers.
I agree with the bumper regulations too, I think it looks much more professional if you have actual bodywork covering the tubes. Not to say some tubular bash bars don't look awesome and Mad-Max, but for a competition trying to attract average viewers and connect with brands, it's a better direction for cars to be recognizable. Chelsea's rear shock-absorber thing (originally a Bergenholtz creation) can still be achieved with curved thin wall tubes acting as springs. You could even do flexure joints.
I like that you can't remove the whole parcel shelf now too.
No change to suspension between tandem runs is definitely a good rule. Everyone runs different setups in lead and follow so it's hard to gauge how your opponent is actually going to perform. I mean, that's fine cause it's legal, and I guess helps when you have to follow a slower car, but at least you can still raise tire pressure if your car is honestly too fast trying to follow a terrible car.
They should probably add a hand-brake light. Basically a blue led strip right along with the red one so the judges can see clearly who is riding handbrake and also catch small corrections even in the smoke.
One thing I really wish they would change though; just mandate a minimum tire pressure like every other race series in the world. So now you have to run a DOT wheel and NOT add knurling, bite grooves, or anything else to help the damn tires stay beaded. Well teams are going to run 6psi if they can legally, and always be on the edge of de-beading a tire.
Yes that's the competitors problem if they get DQ, but honestly, it sucks for the fans. We want to see every battle end with a WIN, not technicalities.
Just mandate a tire pressure already. 15psi at ambient temp, done.

Yeah I believe he's done. His crew chief opened his own shop down here and the other guy who worked on the cars left to WA. So unless Wang is planning a 1 man show he's out. I haven't seen his cars for sale though?
I have always thought the same thing. Also enforcing the brake light rule more. Like when Forsberg went into Wang and his brake lights didn't work and that whole controversy.
I don't know, maybe they should rely on something more reliable than ebay LED strips 3M taped to windshield with shitty solder contacts.

This is what I saw, but I can't tell who posted it.

Also, I was under the impression the handbrake was lit via an inline brake light switch? I never really paid attention though.
I am honestly suprised wheel tethers aren't mandatory after the recent death in Japan to a spotter
Yea, for sure that's probably what prompted that, however wheel tethers aren't really all that successful, especially with heavy street wheels and tires. Even in F1 they often break the tethers and the wheel flies of anyway. They're also not cheap for good kevlar ones.
Also obviously it's impossible to tether just the wheel, so you're looking at the wheel, hub, knuckle, caliper, rotor and strut or trailing arm. So much weight there.
The lost wheel issue is much more often caused by crap wheel studs and aluminum or titanium nuts. I don't think I've ever seen a full wheel/knuckle, brake assembly come off and travel any real distance in FD. Working out the tether attachments to the knuckle and chassis also is a consideration.
Mandate quality BBS or ARP wheel studs, and steel nuts only. I've used that forever and never had a problem.

True. If I read correct info, the death was caused by a complete knuckle/hub assembly detaching with the wheel, rather then just the wheel coming off, but yeah 99% of them are people too lazy to torque lugnuts. I also read (like you said) that f1 wasn't having good luck with them.
Oh man, If Honnadell showed up in an E46 that would be amazing. He's already one of my favorite driver's, to see him slaying in a BMW would be great.
My guess is that they want to keep the cars as relatable and recognizable as possible to increase manufacturer sponsorship potential

Who would fill them. And with what? Why?All bumper tubing must remain hollow.
Status: Someone put glitter in my oil. Wait. Why's all my oil outside the engine? What's that knocking?
They used to flat out require an OEM dash, at least they let you use fiberglass ones now.

And yep I think this. They want the cars to be relatable to keep people interested.

I think some people use thin wall tubing and fill it with a sort of foam as a crash structure? Sean mentioned it in my build thread
Update on Forrest. Won't be competing

That's a huge bummer. Oh well, maybe he'll come to another drift colorado event sometime then! haha
