FREQUENTLY ASKED QUESTIONS
What is the lead time for your kits?
The SONIC is now back in production for 2026. Estimated lead times are 3-4 months, depending on specification, and there will be a build queue. The estimated delivery date will be agreed with you prior to the placement of your order.
Are you able to provide a fully built ‘Turnkey’ vehicle?
EKC do not offer factory builds directly; we are only able to manufacture the SONIC in kit form, for the foreseeable future. However, if you are looking for a part or fully built vehicle, we have a relationship with BC Cars Motorsport in Suffolk, who will be happy to build the vehicle to your specifications for you. You would buy the kit from EKC, and we will supply it directly to BC Cars on your behalf. They will then take it from there and complete the build as per your specifications. You’ll deal directly with them so that you have full control over specification and cost, but we will support them whenever required, to make sure you get the car of your dreams.
Is this a ‘kit-in-a-box’ or will I have to source components myself?
The SONIC is not a ‘kit-in-a-box’, and you will need to source some parts for yourself (although a lot of these can come from the same donor car). EKC can provide many optional extras to help with this, but there will always be parts you need to source for yourself – choosing your own is part of the fun!
How much will a completed kit cost?
The price of the basic SONIC kit is approximately £9,995 (there's no VAT to pay), but will vary heavily dependant on specification. Please discuss your requirements with us and we will provide you with a personalised price.
Is there a build manual?
There is a detailed build manual which contains all the information necessary to assemble the standard kit. We are currently in the process of updating this and will provide a manual with all kits sold.
Do you ship worldwide?
Sorry, no. All kits are ex-works and need to be collected from our premises in Cambridge. International customers are welcome to arrange collection themselves or via a 3rd party shipping company. Please get in touch with us if you wish to discuss this further. Please note that our insurance does not cover us for sale of products to the US.
I’m an international customer, will I be able to register my SONIC in my country?
Unfortunately, we can’t advise on this, road vehicle legislation varies from nation to nation, and the standard SONIC has only been designed with UK legislation in mind. There is lots of consistency with legislation abroad, but EKC are unable to offer any further guidance on this. Please ensure you understand the legislation in your country before ordering, as we will be unable to refund/support issues with registration abroad. If you know of a specific issue with registration in your, then we are happy to assist with this as best we can. Please contact us to discuss prior to ordering. Please note that our insurance does not cover us for sale of products to the US.
Which bits of the SONIC can be customised?
It’s probably easier to list the bits that can’t be! The scope to customise the SONIC is huge and that’s one of the things that make kit cars so great. The standard kit can just be the starting point of wherever your imagination takes you. All our engineering is done in house by Equilibriums’ owner Mike, who is a Chartered Mechanical Engineer with nearly two decades of experience in design, development, and testing of special purpose vehicles. If you have specific questions about customising the SONIC please just ask!
I saw the SONIC ‘Wraith’ at a show. Can I build exactly this car?
The ‘Wraith’ has been extensively customised, but it started life as a standard kit, so you certainly can build a SONIC kit to this level. Some of the special features of the ‘Wraith’ we plan to offer as optional extras (boot & bonnet hinges, 8” rear cycle wings, folding number plate mount, etc), but there are some one offs we do not currently plan to reproduce. Please discuss your requirements with us before ordering, so that we can tailor your kit to your needs.
Can I use a different donor car, if I’m not keen on the Ford Focus?
Yes, you can, but many of the physical mountings on the chassis are designed to take Ford Focus components (engine mounts, hand brake, steering column, etc), and are unlikely to fit other vehicles’ components. If you’re comfortable grinding and welding, then you can customise whatever you like (although, please note that this will invalidate the stress analysis data, and hence is entirely at your own risk), but be aware you can’t just purchase a different donor and expect it to fit. Please contact us with special requests, and we will see what we can do to assist.
Can I use my SONIC as a track day / racing car?
You can, but it is not designed with that purpose in mind, so please check the regulations of the type of track day / series you plan to run at. There may be special requirements that you need to comply with. As an example, the SONIC does not currently have a MSA specification roll cage. Unfortunately, our insurance does not cover us for this, so use of the vehicle for any motorsport purpose would be entirely at your own risk.
Can I go electric?
We would love to support electric vehicles 100%, but unfortunately the legislation/route to approval is far more challenging, and requires lots of expensive testing. As things stand, if you want to go Electric, EKC will be happy to support you as best we can, but we can’t guarantee that it will be possible / cost effective to make your car road legal.
I am disabled and require special access/controls to drive. Will a SONIC accommodate me?
There should be no reason why you cannot build and drive a SONIC, but this will depend on the nature of your disability and the relevant legislation. There are disabled teams entering and completing the Dakar rally, so building a SONIC should be easy by comparison! We will help with this as far as is possible, so please contact us to discuss your build and we do whatever we can to support you with this.
