AC Cobra Full Vehicle Restoration with Redline Engineering

Harry Pitcher • April 15, 2026

This AC Cobra Mk IV came to d:class as part of a collaborative restoration with our good friends, Redline Engineering UK. The customer wanted the car completely refreshed with a new body colour, mechanical overhaul, new exhaust, wheels, a full interior retrim, and more. We were tasked with retrimming the vehicle but ensuring to keep it traditional. So no new radios, switches, or any other modern upgrades to distract you from this beautiful car.

Keeping things traditional, we selected a black Wilton carpet for the car. So we removed the old carpet, removed any old glue to ensure a fresh base for the new carpet. The floor, inner sills, centre tunnel, rear bulkhead, over mats and doors all get trimmed in carpet on a Cobra, leaving only the dashboard, seats, and any carpet binding to be trimmed in leather.

The seats came to us just as metal frames, so we were tasked with creating the rubber belts that act as the spring in the seat, followed by adding the foams for added cushioning. Through much testing (bums in seats) we achieved the perfect balance between comfort and support.


Vaumol crushed grained black leather was used for the seats and dashboard, which looks absolutely perfect in this car. Really in keeping with the style and heritage of the vehicle. We then added the new Smiths dials, the 4-point harnesses, boot floor, over mats, and installed the centre console, completing this interior retrim.


There was a gap in between the retrim as the owner decided in for a penny, in for a pound, and changed the cars colour from the dark green to Carbon black.

AC Cobra MK IV Full Restoration

By Dave Price • May 7, 2026
This AC Cobra is another full interior retrim completed as part of a vehicle restoration collaboration with Redline Engineering . This is the second project we have recently carried out in partnership with Neil and his team, and the specification for this one is truly something special. The customer requested a tan Connolly leather, and after working closely with both them and Neil from Redline, we settled on Parkside Caramel nappa leather. It was an incredible choice, the super smooth finish and rich colour work perfectly with the Guardsman Blue metallic paint. We then needed a carpet that complemented the leather equally well, so a biscuit-coloured carpet from Boyriven was selected. New dials and gauges were installed, alongside new seat harnesses.

Porsche 911 Carrera 4S Houndstooth Retrim

By Harry Pitcher • May 5, 2026
This Porsche 991 911 Carrera 4S belongs to another customer who has recently seen the influx of Porsches across our socials and blog. They have also requested the very sought-after houndstooth seat centre retrim. They have selected a black and red houndstooth for their seat centres and door card centres to be retrimmed in. A great choice, that also matches the black of the car and the red of the seat belts and calipers. Whilst we had the car, our customer also opted for a steering wheel retrim. Nothing crazy for this one, just a like-for-like OEM retrim to the same spec. Black nappa leather with black stitching and black racing band.

Ferrari 488 GTB Wheel Retrim

By Harry Pitcher • April 28, 2026
This Ferrari 488 GTB came to d:class for a steering wheel retrim, despite only showing light signs of wear. Having recently changed hands, the new owner wanted the car to feel completely their own. Starting with the one part you touch every time you drive. A fresh wheel makes all the difference, complemented by the installation of new steering wheel buttons to complete that factory-fresh finish.
