M-Technic 1 vs M-Technic 2 — the BMW E30 aero kits explained
Published July 8, 2026
BMW offered two factory M-Technic body kits for the E30, and they are the most sought-after exterior parts on the car today. They look related but they are different kits, designed for different cars, and the parts are not interchangeable without modification. Here is how to tell them apart and which one your car needs.
M-Technic 1 — the pre-facelift kit
M-Technic 1 was fitted to pre-facelift E30s (built up to the September 1987 facelift). It is the subtler package: a front spoiler lip that mounts below the chrome-era bumper, side sill trims, and the distinctive rubber-look rear spoiler on the boot lid. Inside, cars specified with the package got the three-spoke 370mm M-Technic 1 steering wheel — itself a collector item now.
Because the kit was designed around the earlier metal bumpers, M-Tech 1 parts will not line up correctly on facelift cars with plastic bumpers.
M-Technic 2 — the facelift kit
M-Technic 2 arrived with the facelift and fits E30s built from late 1987 onward. It is the aggressive kit most people picture: a deep one-piece front bumper spoiler, sculpted side skirts, rear bumper extensions (the "pods"), and the two-piece rear spoiler with its rubber upper blade. The matching interior piece is the four-spoke 385mm M-Technic 2 steering wheel.
Genuine M-Tech 2 parts are among the hardest E30 parts to find in good condition — the front spoilers scraped on everything, the skirts caught stone chips, and the rear spoiler rubber shrinks and cracks with age. Original, uncracked examples command strong prices, which is also why reproductions are common: genuine parts carry BMW part numbers moulded into the back.
Which kit fits my E30?
The short version: pre-facelift car (chrome-style bumpers, up to 1987) → M-Technic 1. Facelift car (plastic bumpers, late 1987 to 1994) → M-Technic 2. Mixing the kits requires cutting or adapting because the bumpers, valances and mounting points changed with the facelift.
When buying used parts, check for cracked mounting tabs, previous repairs on the lower lips, and — on the M-Tech 2 rear spoiler — the condition of the rubber insert, which is the part that ages worst. Every M-Technic part we sell is photographed exactly as it is, flaws included, so you can judge condition before buying.
