Is it possible to build a 4 wheel kit car that is below the required weight and register it as a 3 wheeler?
Hmmm,
Is the answer not in the question?
required weight for what...?
Is there a lower limit...?
Iv never heard about a weight limit.. I dont think anyone would call a 4 wheeler, a 3 wheeler. Hope im wrong though, sounds like a good idea
Not to sure but head if a 4 wheel car is below 400kg then it can be classed as a Quadricycle

How can a 4 wheeler be classified as a three wheeler? Id love some of the drugs you smoke.
Surely, regardless of weight, if it has four wheels, then its a four wheel vehicle?
found this
Quadricycle is a 4 wheeled vehicle of which there are two classes:
(i)
light quadricycles whose unladen mass is not more than 350kg, not including the mass of the batteries in case of electric vehicles, whose maximum
design speed is not more than 45km/h. These vehicles shall be considered to be mopeds and shall fulfil the technical requirements applicable to 3
wheeled mopeds; and,
(ii)
quadricycles other than those in (i), whose unladen mass is not more than 400kg (550kg for vehicles intended for carrying goods), not including the
mass of batteries in the case of electric vehicles, and whose maximum net engine power does not exceed 15kW. These vehicles shall be considered to be
motor tricycles and must fulfil the technical requirements applicable to motor tricycles

20bhp or 45kmph, doesnt sound like a sports car to me

<350kg and 45 km/h is classed as a 4 wheel moped.
<400kg and 20.1 BHP or less is a heavy quadricycle. It can be as fast as you can make it. Is tested under MSVA rules rather than IVA.
You have to have 3 wheels to be a trike. It also has to be less than 1000kg to be road legal.
have judt found this
Restrictor. Although there are no requirements that say that a quad on the road has to be restricted to 15kw, or 20hp, for the test, a restrictor
needs to be fitted. This can be done a number of ways, but check with your local SVA centre which method they accept.
You'll also need a dyno print to prove the power when you take the quad along for the test

ISTR that if two wheels on one axle are close enough they are considered as one? It's a bit of a hazy memory but I recall reading something along
these lines quite a while back.
John.
I've seen a "trike" with four wheels, but I don't know what it was registered as.
Think of something based on a 2CV with the rear arms turned round, so that the rear wheels are almost touching each other.
