Interesting versions of cool vintage cars. Can any one tell me what exactly these are?

Can any one please help! I have spent several hours (more than I'd like to admit lol) googling my way through the back parts of the internet trying to work out what exactly these are. I can find plenty about the 'normal' versions of these cars but can't find anything on what these clear chassis colored wheel versions are.

PH BRICKYARD RACERS I have questions newbie here

Saving up so I could use the track in Brickyard. I will not be joining races, just practice runs. But since Brickyard is "all tamiya branded only" I wanted to ask

  1. Is using outside motor oil like loctite, chaos drop, top speed, or even sonic boom allowed?
  2. How about in grease? Is using grease pens like nugrizz allowed?
  3. Are you allowed to bring lighter fluid there incase you need to clean your motor?
  4. Is practice runs has a fee or it is free?
  5. Are there services such as wheel alignment and piercing, motor break in etc.?
  6. Are batteries necessarily tamiya brand like neochamps?

Are laterally damped front bumpers useful on 3-lane tracks?

I often see many Jump Open-class Mini 4WD builds online using front bumpers with lateral damping systems, such as O-rings or spring sliders.

I understand why these can be useful on digital turns, where the car receives a strong side impact. But are they actually useful on a standard 3-lane track?

If so, in which situations do they provide a real advantage?

The reason I’m asking is that most Open-class Mini 4WD builds I see online seem to use some kind of laterally damped front bumper. However, digital turns do not seem to be very common outside of Japan, and when they are used, they are usually found on 5-lane tracks rather than standard 3-lane layouts.

So I’m wondering: are O-ring or spring-slider front bumpers genuinely useful for 3-lane racing, or are they mostly built for digital turns and specific Japanese-style layouts?

I’d like to understand whether this setup has benefits on normal 3-lane tracks, such as improving stability, reducing bounce after wall contact, helping with lane changes, or absorbing impacts from technical sections.

UK Clubs

Hi all, I was wondering if there's any UK clubs or anything that are active, in particular around Derbyshire? I know about https://www.mini-4wd.uk/ but it doesnt seem to really be active anymore?

I have a couple of cars (one doesn't have a shell as it was bought as parts as a Project D car), and i do have a 3 lane track, but i dont know anyone or anywhere around me that has interest in the hobby.

Monthly BMAX race at Modojo (HK) - Longish 3 lane track

Monthly race at Modojo in Hong Kong!! and my second last race in hong kong before heading back to Canada

One of the... more challenging courses for my MA chassis, suprisingly one of the top 3 winners was running an SFM with 5:1 ratio gears to tackle the technical sections (i believe he ended up 2nd, he helped me adjust my car at the end of the race there's a run of it)

this track is desceptively simple, i thought i would go full speed machdash, but i can't go too fast here or the bathtub (table top up and down) or the double slope jump or the table top jump or jump into a lane changer will get u... (my god this was a nightmare for my MA chassis, and it turns out I wasn't choosing the right setup idea for this track, good learning experience).
