Whakaotihia te rerenga e whai ake nei: I te tau 1985 me te 1986, i timata a Lammers i te 10 CART World Series mo nga roopu rereke e wha. Ko tana mutunga pai ko te tuarima i Laguna Seca Raceway i te 1985 mo Forsythe Racing. I whakauruhia ia, ā, i whakangunguhia hoki mō te
1986 Indianapolis 500 i te urunga a Mike Curb, engari kaore i ngana ki te tohu. I mutu ia i te 26th me te 22nd i roto i nga tohu i roto i ona tau e rua, i runga ake nei. Whai muri i tera ka tahuri tana aro ki te whakataetae motuka hākinakina.
