Thinking I am getting to old for tents, so thinking of small trailer tent.

Has anyone fitted tow ball to the car? If I was going to fit my own what thickness steel would be appropriate? On the zero I think I could easily pick up on chassis and lower wishbone arms and believe they would take the weight. Only going for a small 2 berth, possible a motorbike tent or small Comanche.

Ideas please or some who can build to my specs.

Interesting challenge. Given the tank position, assuming you didn't want to interfere or change the tank at all, I think you're stuck with a rather low hitch height if you're picking up off the lower section of the chassis... I wonder if it would be too low? Obviously you could rise it up on the outside of the car, up at the back, but I wonder what strength/leverage stress this would put on the rest of the structure. I guess ultimately if you use thick enough steel, anything should be possible, but given the Zero rear end in the early days was known to fracture in places before GBS added webbing/strengthening, I'd be cautious about how much "safety margin" is in it, to be honest...!

will watch with interest but did not think the rear would be strong enough for a tow bar

Something to think about before you go ahead, copied from bosal website


Tow bar design

Tow bars are reviewed on an individual basis, and only those that meet the European Courts safety and quality standards are considered type-approved. As of 1998 in the UK, only Whole European Type-Approved Vehicles can be fitted with European Type Approved towbars. To ensure that the tow bar you are purchasing is safe and compliant, always look for the type approval plate.

Manufacturers design towbars using data such as;

The car manufacturer's specified fixing points

Gross Trailer Weight

Gross Vehicle Weight

As this data varies depending on the make, model and year of the car, it is important that you invest in a (type-approved) vehicle-specific tow bar.


I've done it but won't any longer, if it's not type approved it's not legal in my understanding of it. Have an accident whilst towing I think it would be a world of legal pain.

Just my interpretation of it...

Agreed, after reading that, if that's the legal position, I wouldn't be bothering (well, I wouldn't be bothering with a Lotus 7 and towing anyway, but, you know what I mean ;) )....

Also i am led to believe cant fit a towbar unless qualifed due to insurance will be invalid
Will it ever be a good runner ?

I expected that my MX5 MK3 would be able to tow a small camping trailer, but the logbook states 0KG as the max towing weight.

MX websites have lots of info, although MK1s & 2s have a low towing weight specified.

There are lots of warnings of being uninsured etc if you try......so regrettably I wont.


It always takes longer to put it right than do it right.

Legally its a big no to fitting a tow bar to virtually any kit car.

 

As Dan says all tow bars must be type approved if fitted to vehicles registered after 1.8.1998.

 

A non type approved tow bar will breach the construction and use regulations and therefore be an offence.

 

Since it is unlikely that the vehicle was registered with any towing weights specified it will not have a plated gross train weight and so will be overladen if towing any trailer. Another offence.

 

Unless you declare the tow bar to your insurance company, your insurance will be voidable, which means the insurance company can refuse to cover you in the event of an accident.

 

It is possible that with such a lightly constructed car, overladen (see above) with a non type approved tow bar, that consideration would be given to a prosecution for driving a vehicle in a dangerous condition (S40A RTA 1988) which carries 3 points and a fine.

 

If there was an accident the it could be Dangerous Driving.( a mandatory ban, retest and possibly imprisonment)

 

Its more likely to be VOSA than the police who pull you over for a stop check at one of their roadside check points.

 

Having built a zero and had it rear ended I would not be putting any extra load on the rear end or be drilling any additional holes in the box section.

 

I hate tents too so sorry to put a damper on your plan.

I was looking at a camper van and tow the kit, but wheres the fun in driving the kit. OK for some events where you can park up, pitch up and enjoy. Other options, Hotel starts to be expensive, plus I dont trust most Hotel carparks. I stay away 2-3 days a week with work and carparks are like a dealership for the less scrupulous members of the public. Plus you miss out on the fun and comradeship.
Plan B then...
