You have picked out the kit \u2014 a front bumper, side skirts, a rear diffuser, a wing. Then you read about A\u0130TM, TSE approval, a modification inspection and a trip to the notary, and it sounds as if a styling upgrade has become an engineering project.<\/p>\n

The piece of information that changes everything is this: not every part requires a project.<\/strong> Turkish rules draw the line at whether the change affects the vehicle’s technical data. Simple accessories that leave the car’s technical features, dimensions, weight and fuel system untouched do not need a project \u2014 and that description fits a normal bolt-on styling kit.<\/p>\n

So the straight answer is: a body kit is legal in Turkey.<\/strong> A cosmetic kit that bolts on and changes nothing on paper is the easy case. A kit that changes your car’s dimensions or adds significant weight moves into the A\u0130TM project route, with TSE approval, a modification inspection at T\u00dcVT\u00dcRK and an updated ruhsat<\/strong>. This guide explains both paths.<\/p>\n

The short answer: body kit legal in Turkey comes down to your car’s data<\/h2>\n

Turkey’s core principle is simple and strict: the technical specifications of a vehicle on the road must match the data in its registration document (ruhsat).<\/strong> If the physical car and the ruhsat disagree, the vehicle can be banned from traffic and heavy fines can follow.<\/p>\n

That is what the modification rules exist to manage. The governing framework is A\u0130TM<\/strong> \u2014 the regulation on the manufacture, modification and assembly of vehicles \u2014 and the process runs through authorised mechanical engineers and TSE. What matters for an owner is the threshold:<\/p>\n

What actually triggers a project in Turkey<\/h2>\n

The clearest way to understand the rules is to look at the work that always needs one. Turkish engineering guidance lists the classic cases: adding or removing seats, cutting windows into a panel van, caravan conversions, wheelchair-access conversions, body or cargo-box changes, engine replacement, and heavy insulation or cladding that changes the vehicle’s unladen weight.<\/p>\n

Against that list, a bolt-on styling kit that leaves the car’s dimensions and weight alone is a different category. Turkish practice states it directly: simple accessories that do not change the vehicle’s technical features, dimensions, weight or fuel system \u2014 such as roof rails or simple audio upgrades \u2014 do not require a project.<\/strong> That is the rule that keeps a carefully chosen body kit simple.<\/p>\n

Where owners get caught is weight and dimensions. If your kit makes the car wider, longer or noticeably heavier, you have created exactly the kind of change the project process exists to record \u2014 and the fix is not to hide it but to document it.<\/p>\n

The project route, step by step<\/h2>\n

If your modification does need a project, the Turkish process is well established and, in 2026, largely digital:<\/p>\n

    \n
  1. Work with a TSE-authorised mechanical engineering firm.<\/strong> The engineer calculates the vehicle’s new state, produces the technical drawings, and prepares the project file.<\/li>\n
  2. Go to a TSE Vehicle Inspection Centre (AKM).<\/strong> The vehicle is physically checked against the project, and the materials used \u2014 E-marked glass, seat belts and similar \u2014 are verified against the standards. This is where cheap, uncertified parts fail.<\/li>\n
  3. Attend the T\u00dcVT\u00dcRK \u201cmodification inspection\u201d (tadilat muayenesi).<\/strong> This is separate from the periodic inspection, although the two can be combined if the periodic one is due.<\/li>\n
  4. Complete the registration at a notary.<\/strong> Once the TSE and T\u00dcVT\u00dcRK approvals are in the system, the new registration document (tescil belgesi) is issued.<\/li>\n<\/ol>\n

    There is a deadline that surprises people: after TSE approval, the vehicle must attend the T\u00dcVT\u00dcRK modification inspection within about 30 days<\/strong>, and the registration should then be updated. Leave it longer and you may face penalties or need to renew the project.<\/p>\n

    One practical lesson runs through every Turkish guide on this subject: use a licensed firm and E-marked or certified parts.<\/strong> Unlicensed workshops using uncertified materials are the most common reason a project fails at the TSE stage \u2014 and the reason owners pay twice.<\/p>\n

    Who does what: you, the seller, the workshop and the engineer<\/h2>\n
    Who<\/th>What they handle<\/th><\/tr><\/thead>
    You<\/strong><\/td>Choose the parts, confirm whether a project is needed, and keep the documents<\/td><\/tr>
    The seller<\/strong><\/td>Accurate product information: the exact part, the model and year it fits, the material, the weight, the mounting points and photos of the fixings<\/td><\/tr>
    The workshop<\/strong><\/td>Fits the kit properly, with compliant materials and correct fixings<\/td><\/tr>
    The authorised engineer \/ TSE<\/strong><\/td>Where a project is required, prepares the file and checks the vehicle against it<\/td><\/tr><\/tbody><\/table><\/figure>\n

    What you want from the seller is accurate information about the part and the car it fits: the correct part number for your model year, the material and weight, how it mounts, and photos of the fixing points. That is what your workshop works from and what an engineer will ask for \u2014 and it is what we send with every kit we ship.<\/p>\n

    Fitment: model year, drilling, and going back to stock<\/h2>\n

    A body kit is not a universal product, and BYD’s line-up proves it. A Seal, an Atto 3, a Dolphin, a Sealion 7 and a Shark 6 share almost nothing at the mounting level, and facelifted versions of the same model can change the bumper shape, the sensor layout and the tow-hook cover.<\/p>\n

    Before you buy, give the seller the model, model year, trim, market version and VIN<\/strong>. A supplier that will not ask for the VIN is guessing. Our BYD model lineup<\/a> is a useful starting point if you are still confirming which generation you own, and our BYD exterior accessories<\/a> hub lists styling parts by model.<\/p>\n

    Three fitment questions matter more than any photo:<\/p>\n
