Spencer has acheived second place LMP2 finish at Petit Le Mans in 2004, and Podium finish in 2003 at Road America in the Zip Racing Porsche GT3-RS with Andy Lally (who is also vegan). He has three career wins and eight top 3 finishes in 23 races.
"I am very passionate about both animals and health, and I want to do more to promote both...I knew vegan was the right thing to do, but I always figured it would be too hard with all the traveling I do. I decided to give it a try last summer when several things, including my favorite local pizza joint starting to carry Daiya non-dairy cheese, seemed to point me in that direction. After a few weeks of adjusting, I now find it quite easy no matter where I go."
