Specification and installation

Products sold by the company will include specific disclaimers written by the respective manufacturer. The company shall not be liable for any loss or damage in any form howsoever arising from the use of items provided. Where relevant, items will include safety information & disclaimers in their packaging

All seat brackets, fitting kits, brake kits and vehicle specific components sold are designed for on the base model of any particular vehicle variant. If the listing states a specific version of a vehicle, we can not guarantee fitment to another variation within the same model range. For example, seat frames listed for a Mitsubishi Lancer Evo X are not suitable for the standard variation of Mitsubishi Lancer. Another example is that a big brake kit which is listed for a BMW E46 will be based on the standard BMW E46 variation and will not fit the BMW E46 M3. It is the customer’s responsibility to make us aware of any particular model variations at the time of order to ensure production is correct and accurate, otherwise, the parts will be produced to the base specification

Helmets and HANS posts: A high proportion of helmets are supplied from the factory with HANS posts as standard. In the event, you do not select HANS posts we will have these removed for you and your helmet then be dispatched. You may see residual marks from the adhesive used. 

Please note: Aftermarket fitting frames are not suitable for OEM seats taken from a vehicle that was factory fitted. With thousands of variations, installation points, and seats. It is not possible for us to confim fitment without prior advice.

We supply a wide range of seats built to various levels of quality depending on the manufacturer, source of components and type of use expected. Entry level seats produced by Auto Style, FK Automotive, as well as the Corbeau NFX, DFX and Club Sport seats do not use UV protected fabric and may experience colour degradation faster than their FIA approved counterparts. When seats of this nature are used in convertible vehicles and exposed to an excessive amount of sunlight, the colour degradation of the seat may also be accelerated and is not covered by the manufacturer warranty.

This does usually affect colours like red, blue, green or bright colours in general due to the material. 

When purchasing seats and seat frames as a package, please check to ensure that the products can work together, with or without some form of modifications (where required). If your original seats have SAB (side airbags), please ensure to check this as additional resistor kits may be required when installing the new equipment. We recommend that this electronic equipment is installed by a highly-skilled & professional auto electrician. If your passenger seat has an occupancy sensor we would also recommend installation by an auto electrician, as modifications to the vehicle’s wiring may also be necessary.

Seats are entirely universal and are not sold to be installed or fitted directly in any one given vehicle. The professional installation and wiring of each product will be the responsibility of the professional completing the installation. 

GSM Performance does not guarantee the size fitment for any seats, harnesses and/or universal products due to varied vehicle interior dimensions and configurations. Please use the product dimensions provided to compare with your existing layout to determine fitment. GSM performance will not be held liable for incorrect assessments regarding fitment.

  • A huge range of the seats we sell are handmade including all bespoke and custom seat designs. When producing these products there are a number of different variables within the production process which include: Different trimmers, the shade of fabric colours, material batches, stitching colours, logo designs, and logo placements. Each of these variables means that seats produced one week to another can have minor differences and may not match.
  • When the covers are fitted to the shells of seats, they are hand stretched around the shell they have no guideline to work to so each seat is slightly different. The only way to guarantee a match is to produce the seats at the same time, from the same roll of the material, with the same trimmer producing them, and being completed together to ensure the covers are fitted together and matched together. The number of variable factors of handmade products means that producing 2 identical products at different times is very difficult and can never be guaranteed.

Product disclaimers

Products sold by the company will include specific disclaimers written by the respective manufacturer. The company shall not be liable for any loss or damage in any form howsoever arising from the use of items provided. Where relevant, items will include safety information & disclaimers in their packaging.

  • Custom Steering Wheels: The replacement of the steering wheels on cars equipped with airbag systems will disable both the functioning of the airbag of the driver and that of the passenger or any other airbag fitted to the car. For cars equipped with airbag systems, aftermarket steering wheels are intended for racing and show use only. Do not attempt to install any equipment yourself unless you have been properly trained in the installation and maintenance of car steering wheels. Do not attempt to install any kit without having previously read the instruction manual. Incorrect installation can lead to steering wheel failure, which can cause an accident resulting in serious personal injury or death. Reduced steering wheel diameter will cause increased driver steering effort.


All the advice provided is based on previous customer cars, various projects, and personal experience. But we are all different shapes and sizes, we all have different requirements, and we may want our products to fit differently. It’s such a personal service that we can’t get advice right over the phone/email every time. Our advice is just that, advice, and not a promise of perfect fitment for your needs. So please take care when your product arrives to sit in it or try it on to ensure you like the sizing before installation. Products can not be returned after installation and careful consideration should be made when picking products without prior testing. 

All quotations, indications of costs, and financial commitments given or made by the Seller are based on the assumption of the validity of the information provided is fully accurate and correct in all circumstances. 

Quotations provided by email, message, or phone are not part of contract. When ordering products online please take care and attention to double check and verify product specifications, and vehicle information. Delivered products are delivered to the order specification and not separate quotations. 

GSM Performance maintains the right at any stage to re-negotiate any contract, cost agreement or any other relevant commitment should any information provided by the Purchaser fail to be fully valid accurate and correct. This includes Verbal and written quotations which are valid for 30 days subject to these terms and conditions and supplier pricing adjustments.

Order confirmations

Your order is accepted at the point the items are dispatched and delivered. Until this point, we have the right to withdraw the product from sale, cancel and reject the order. Our email confirmations are an acknowledgement of receipt only. In the unlikely event that an error has occurred with online pricing, we maintain the right to reject the order at any point until the items have been dispatched and delivered.

  • The ‘confirmation’ stage sets out the final details of your order. Following this, we will send to you an order acknowledgement email detailing the products you have ordered. Please note that this email is not an order confirmation or order acceptance from GSM Performance. The email/SMS is an acknowledgement of your order, and does not constitute acceptance.
  • Acceptance of your order and the completion of the contract between you and us will take place on dispatch to you of the products ordered unless we have notified you that we do not accept your order or you have cancelled it (please refer to Returns and refunds).

Handling complaints

In the unlikely event of a complaint, we promise to deal with you in a fair, confidential and effective manner. Your complaint will be acknowledged within five working days and you will be kept informed of our progress. We take customer service very seriously at GSM Performance and will always make every effort to resolve any dispute to its positive conclusion.
