Well, I see after buying it that it now says on the website description that it should be used TOGETHER with the original chassis which is impossible as all screws would need to be 2mm longer and the chassis at the front of the carbon fiber is not bent upwards so I will never fit! They do now have a 5mm version that apparently does not bend at all but remember that you will need to replace every screw and bolt with 3mm longer versions! My kit is the 2mm kit. The shock towers are 2.6mm. <br />Get them here: Carbon fiber chassis kit (5mm): <a href="https://shop.makerfire.com/products/carbon-fiber-upgrade-wltoys-104001?variant=39745072169157&aff=231" target="_blank" rel="nofollow">https://shop.makerfire.com/products/carbon-fiber-upgrade-wltoys-104001?variant=39745072169157&aff=231</a><br />Carbon fibre chassis kit (2mm): <a href="https://shop.makerfire.com/products/carbon-fiber-upgrade-wltoys-104001?variant=39745072169157&aff=231" target="_blank" rel="nofollow">https://shop.makerfire.com/products/carbon-fiber-upgrade-wltoys-104001?variant=39745072169157&aff=231</a><br />WLToys 104001: <a href="https://www.banggood.com/custlink/DGKyo9HPmP" target="_blank" rel="nofollow">https://www.banggood.com/custlink/DGKyo9HPmP</a> Use code: BGvehicle for money off. <br />Banggood Carbon fiber chassis kit: <a href="https://www.banggood.com/custlink/3mDyONFKgC" target="_blank" rel="nofollow">https://www.banggood.com/custlink/3mDyONFKgC</a><br />Aliexpress Carbon fiber chassis kit: <a href="https://s.click.aliexpress.com/e/_98F3t7" target="_blank" rel="nofollow">https://s.click.aliexpress.com/e/_98F3t7</a><br /><br />MANY LANGUAGE SUBTITLES ( CC )<br /><br />Use code: BGvehicle for money off: WLToys 124018: <a href="https://www.banggood.com/custlink/3K3yl8u7WO" target="_blank" rel="nofollow">https://www.banggood.com/custlink/3K3yl8u7WO</a><br />Use code: BGvehicle for money off: WLToys 124019: <a href="https://www.banggood.com/custlink/KDKhLi71p9" target="_blank" rel="nofollow">https://www.banggood.com/custlink/KDKhLi71p9</a><br /><br />WLToys K989: <a href="https://www.banggood.com/custlink/33vdLifuJ4" target="_blank" rel="nofollow">https://www.banggood.com/custlink/33vdLifuJ4</a><br />Proper Tyre glue: Proper Tyre glue: <a href="https://hobbyking.com/en_us/insta-flex-plus-clear-rubber-ca-glue-1-oz.html?affiliate_code=IVLPWRGTBRTMRON&_asc=3957490586" target="_blank" rel="nofollow">https://hobbyking.com/en_us/insta-flex-plus-clear-rubber-ca-glue-1-oz.html?affiliate_code=IVLPWRGTBRTMRON&_asc=3957490586</a><br />HOBBYKING USA: <a href="https://hobbyking.com/en_us/insta-flex-plus-clear-rubber-ca-glue-1-oz.html?affiliate_code=IVLPWRGTBRTMRON&_asc=1798483673" target="_blank" rel="nofollow">https://hobbyking.com/en_us/insta-flex-plus-clear-rubber-ca-glue-1-oz.html?affiliate_code=IVLPWRGTBRTMRON&_asc=1798483673</a><br />10% OFF CODE- BGAFF10OFF ZD Racing BX-8E: <a href="https://www.banggood.com/custlink/vGGYFZ8YvS" target="_blank" rel="nofollow">https://www.banggood.com/custlink/vGGYFZ8YvS</a><br />ZD Racing BX-8E without electronics: <a href="https://www.banggood.com/custlink/DGKhlCyR2F" target="_blank" rel="nofollow">https://www.banggood.com/custlink/DGKhlCyR2F</a><br />10% OFF CODE- BGAFF10OFF @Banggood <br />JLB Cheetah 120A version with 2 batteries: <a href="https://www.banggood.com/custlink/Gv3dHfdiyz" target="_blank" rel="nofollow">https://www.banggood.com/custlink/Gv3dHfdiyz</a><br />JLB Cheetah 120A version with 1 battery: <a href="https://www.banggood.com/custlink/3KDyF7EZrc" target="_blank" rel="nofollow">https://www.banggood.com/custlink/3KDyF7EZrc</a><br />Xiaomi Fimi X8 SE 2020 version with ONE Battery: <a href="https://www.banggood.com/custlink/KvKh50GPmf" target="_blank" rel="nofollow">https://www.banggood.com/custlink/KvKh50GPmf</a><br />Genuine Original SKYRC IMAX B6 Mini 60W 6A 😍❤️ <a href="https://www.banggood.com/custlink/GmGRVyZ4ju" target="_blank" rel="nofollow">https://www.banggood.com/custlink/GmGRVyZ4ju</a> - <br />WLToys 124019 from Makerfire: <a href="https://shop.makerfire.com/products/wltoys-60km-rc-car?_pos=1&_sid=5d830c13c&_ss=r&aff=231" target="_blank" rel="nofollow">https://shop.makerfire.com/products/wltoys-60km-rc-car?_pos=1&_sid=5d830c13c&_ss=r&aff=231</a> use code JohnRobinsonRC at the checkout<br />Or the new 124018 sand buggy from Makerfire: <a href="https://shop.makerfire.com/products/wltoys-124018-rtr-1-12-2-4g-4wd-60km-h-metal-chassis-rc-car-off-road-climbing-truck-vehicles-models-kids-toys?_pos=2&_sid=5d830c13c&_ss=r&aff=231" target="_blank" rel="nofollow">https://shop.makerfire.com/products/wltoys-124018-rtr-1-12-2-4g-4wd-60km-h-metal-chassis-rc-car-off-road-climbing-truck-vehicles-models-kids-toys?_pos=2&_sid=5d830c13c&_ss=r&aff=231</a> use code JohnRobinsonRC at the checkout<br />WLToys 124019 from banggood : <a href="https://www.banggood.com/custlink/DGvy5dMpF7" target="_blank" rel="nofollow">https://www.banggood.com/custlink/DGvy5dMpF7</a> 👍🤙 <br />Wltoys 124019 3 batteries: <a href="https://www.banggood.com/custlink/DKmEPHzH2Y" target="_blank" rel="nofollow">https://www.banggood.com/custlink/DKmEPHzH2Y</a> 👍🤙<br /><br />4PCS ZD Racing 8481 F<br />...<br /><a href="https://www.youtube.com/watch?v=A1vPNgEXunU" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=A1vPNgEXunU</a>
