Sidecar Rules?

[Pumba]

Look I don't want to be that guy, and it seems that even mentioning the rules around here opens up a can of worms but based on rule 24.2.3.3 below I would say that every sidecar running kart equipment would be non complying due to the brake discs being to close to the ground?

24.2.3.3 Basic Dimensions:
No part of the construction shall protrude more than 100mm outward from the outside face of the sidecar tyre. No part of the construction shall protrude more than 550mm outward from the centre of the rear tyre. Only streamlining and its support brackets shall protrude in front of the front tyre. There must be a minimum of 75mm ground clearance when the sidecar is loaded with driver and passenger in normal racing positions and all sumps and petrol, oil and water tanks, radiators and associated piping must be adequately protected underneath by at least 14g steel or 10g aluminium guards if they come within 90mm of the ground.

I have been trying to get my head round a few things and have just come to this realisation. Given that I think we are all pretty comfortable with the current building format we may need to look at rewriting this rule for next years rule book submissions.

Spot on. In fact how about rims and sprockets? Are they so different from discs? Unlikely that anyone would ever kick up a fuss but better to have a rule set that actually works than say 'she'll be right'.

Maybe just amend it to state something like:

Parts related to the driving, braking or direct constraining of wheels and axles are only required to exhibit 15mm of ground clearance when fully laden (This does not include engines).

The rules need to differentiate between buckets and full size F2/F1

These are within the Miniature Road Racing rules so no need to worry there.

[nodrog:Me]

that's hilarious, more ground clearance than an adult sized chair.

Sprockets are in the same camp. Rims I see as different, but I guess at a stretch I could see where you are coming from.

As Moooooooooools said, this is all contained with in chapter 24 of the rules so effects nothing outside of that section.

Seriously

Discs and sprockets are usually considered part of the road wheels. Ground clearance rules refer to chassis parts.

Good enough for me. We can close the thread now.

Seriously

yep, 65mm is the ground clearance for normal chairs.

I think those go kart chairs still wont comply, aren't they like 20mm off the ground? 75mm would be well past the axle centre on those little wheels I would have thought.

[Pumba]

Front tires on the 5 inch kart rims are meant to be 10 inch diameter (of course dependant on inflation). Means axle centre should be around the 125mm mark.

Using the rules, all LCR world champ (proper ones, not kiddie size) are illegal because the lower suspension arm is too close to the ground.

yeah, the car world went there in the 1960's when the Lotus 18 appeared with the bottom suspension links at around rim height. lot of angst about that but when the first one lost a wheel and didn't roll but instead came to a safe halt on the suspension everyone heaved a sigh of releif and ignored the naysayers...
It's not a safety issue, in fact it's probably pro safety so it's ignored.
Nowadays IMO, the ride height regs are mainly to stop any ground effect ideas.

They used to use a couple of wooden blocked attached under the chassis if the race ended and they wooden blocks were worn to any certain extent they car was illegally low.
That way no one could fudge the suspension ride heights on the fly.

oh well , time to scrap the sidecar, kart tires only 60mm before hitting rim , at least i have a spear motor

Pffft, stop being a sad prick. I wasn't attacking anyone just seeing if I was looking at it the same as the general masses.

You have been talking about scraping that thing since it turned turtle on you anyway.
