1987 Peugeot 205 GTi Dimma

This lot will be auctioned via Iconic Auctioneers, The Classic Sale at CarFest 2026 on Saturday the 29th of August and Sunday the 30th of August at The Wing, Silverstone Circuit, NN12 8TN.

Introduced in 1985, the wide-body conversion offered by Dimma was based on Peugeot’s T16 Group B rally car of that period. Unlike typical aftermarket body kits of the era, the Dimma styling package carried an official seal of approval from Peugeot, making it one of the most prestigious and highly sought-after modified vehicles of its generation.

Roughly 250 official Dimma-converted 205s were built and sold through a dealer arrangement in the UK. Instantly recognizable, the wide-body kit consisted of flared arches, restyled bumpers, side skirts, and distinctive multi-piece split-rim alloys. The rear wings featured distinctive, Testarossa-inspired strakes and cooling grilles.

This 1987 example is a one-off project built by our vendor, an ex-Peugeot mechanic and enthusiast, to replicate a car he built a few years ago which he "wishes he'd never sold." The car was purchased locally with the kit already installed, and key components have been sourced over time, most recently a 2-litre 16v GTI6 engine.

The engine is a standard xu10j2rs from a low-mileage 306 GTi6 and runs well. The conversion has been completed to a very high standard with all the correct parts fitted and a custom loom to accommodate the standard ECU. Recent maintenance includes a timing belt kit, coolant flush, full service, and gear oil change on the hybrid gearbox, which uses a 1.8 diesel 5th gear and final drive coupled to a Quaife LSD.

Suspension features Gaz 'Gold' coil-overs and Gti6 brakes all around. The rear axle has been rebuilt, and the essential "grease nipple fix" has been carried out.

The interior has been upgraded with a 205 GTi Phase 2 'black' conversion, featuring red carpets, Monaco cloth seats with black leather bolsters, a newly fitted gear knob, and a red-stitched leather steering wheel.

Sitting on genuine Dimma 3-piece split-rims and listed on the Dimma UK Register, this subtly enhanced example offers a more modern level of performance in one of the most recognizable and striking hot-hatch designs of all time.
