Frequently Asked Questions
How much does an M3 or M4 body kit cost in the UK?
Gloss black parts for the F80/F82/F83 start at £79. Carbon fibre parts start at £149 for the F-generation and £199 for the current G80–G83 generation, up to £1,399 for the G80 M3 carbon fibre side skirt set.
Do F80/F82/F83 parts fit the G80/G81/G82/G83?
No — the two generations use different body shapes and are not interchangeable. Check the "Fits" column in the tables above before ordering.
Is carbon fibre worth the extra cost over gloss black?
Carbon fibre is currently only available for the older F-generation as full packages, and is the primary finish for the G-generation. It offers a more premium, motorsport-inspired texture; gloss black is the more budget-friendly route on the F-generation.
Is professional fitting required?
Not required, but strongly recommended on carbon fibre parts given their cost and how visible misaligned panel lines are. KITS UK offers professional fitting with a lifetime warranty at the Featherstone, West Yorkshire workshop.
Are these genuine BMW OEM parts?
No — all parts are premium aftermarket styling components designed for accurate fitment on the specific M3/M4 generation stated on the product page.
Can I pay monthly?
Yes — Klarna, Clearpay and Shop Pay instalments are available at 0% interest at checkout.
