Driving for Nissan, Richards won his third ATCC in 1990 driving both the Nissan Skyline HR31 GTS-R and the mighty 4WD, twin-turbo R32 GT-R, affectionately known as "Godzilla". He would repeat as champion in 1991, finishing the ATCC ahead of his young teammate Mark Skaife. Skaife then put the GT-R on pole position at the 1991 Bathurst, before he and Richards cruised to victory in race record time, a lap ahead of the Holden Commodore of defending race winners Win Percy and Allan Grice.
