Audi S4 B5 1998 Full Restoration Plus Restmod Process
Starting with a very tired and run-down S4, the sole aim was to bring this restro classic back to full health inside and outside with dedicated indepth processes to achieve complete restoration overall with a few upgrades along the way.
The first step was to completely strip the car back to bare bones. All panels, engine, suspension, fuel tank, transmission elements, Interior, glass, and even paint. Due to the storied history present, it was necessary to bare metal this car, so we knew what we could work with moving forward.
A very time-consuming and messy process to remove all underside stone chip and factory applied paint and protection. A few areas needed seen to with the welder and then onto re-applying the layers of protection using epoxy primer, rubberised stone chip and multiple layers of base and clear coat in the cars new colour. All suspension components were either refurbished and powdercoated, upgraded for aftermarket items or replaced with oem branded products. Custom cuprinickel brake lines were made up to replace the rotten old ones, brakes fully rebuilt and upgraded also. All bushes have been upgraded to street spec polybushes with upgrade anti roll bars and extra braces installed for handling improvements also.
Rust, mis-match panels, missing components, various engine leaks, and a plethora of very worn and tired suspension components to contend with.
While the engine was out, it was stripped to bare block and heads, internals examined to be in mint condition and then every seal, gasket, pump, washer, O-ring, sensor and consumable replaced with genuine Audi parts or OEM branded parts when Audi couldn't supply. Some upgrades installed while the engine was out included bigger fully rebuilt turbos, bigger intercoolers, fuel injection and all hard pipes too.
Once the car was in a fit state to be moved again with all the underside processes complete, it then went off for a full repaint at JC Autobody. Months of rubbing down to bare metal and a few repairs saw it come back fully repainted and looking incredible in a genuine modern Audi colour, Tango Red Metallic. Once back in the unit it was time to start on the interior and the rebuild. Interior has been upgraded with genuine Recaro CS seats Custom upholstered in Red Nappa Leather and black Alcantara respectively. Once some progress had been made on getting the car back together, all that was left was for the detailing begin.
This part of the process involved multiple stage wet sanding to level texture in the paint and then a multi stage polishing process to make the paintwork as wet and glossy as possible.
All areas then protected using ceramic coatings and wax and then onto the stands for shows thereafter!
