Porsche’s 1998 911 GT1-98 is having quite a memorable 20th anniversary year. The manufacturer pays tribute to that livery that won overall at the 1998 24 Hours of Le Mans with a tribute livery adorning the pair of Porsche 911 RSRs this weekend at Road Atlanta.

This marks Porsche’s second round of “throwback” liveries this year. Porsche also deployed “Pink Pig” 917/30 and Rothmans-inspired liveries on its two FIA World Endurance Championship-entered cars at Le Mans.

Now, the 1998 liveries are on the two IMSA WeatherTech SportsCar Championship cars for Motul Petit Le Mans this weekend. The GT1-98 car won the pole for the first Petit Le Mans in 1998.

Nick Tandy, Patrick Pilet and Fred Makowiecki unite in the No. 911 car. They won at Sebring earlier this year. Pilet also recently had the chance to reunite with his Petit Le Mans overall winning car from 2015.

Mathieu Jaminet makes his GT Le Mans class debut in the No. 912 car alongside Earl Bamber and Laurens Vanthoor. Gianmaria Bruni had been the third driver earlier this year but is on FIA WEC duty in Fuji this weekend. Meanwhile Jaminet, a Porsche Young Professional, has won this year’s ADAC GT Masters championship co-driving with Robert Renauer,
