In 1990, Speed started only six races with Prestone sponsorship, finishing two of them. The best finish of Lake's abbreviated 1990 season came at Talladega's Die Hard 500 with an eleventh-place effort. Speed also fielded cars for short track ace Tommy Ellis and Phil Parsons in two races. Ellis started the Delaware 500 at Dover in 31st and finished 32nd after an engine failure. In the National 500 at Charlotte, Parsons drove Speed's car with Baja Boats sponsorship to an 18th-place run. 1991 was an improvement in terms of races started. Speed replaced Dick Trickle in Cale Yarborough's car but struggled with mechanical failures throughout his stint with the team. In twenty starts, Speed's best finish was an eleventh at Bristol in August. In 1992, Speed got back to his own team starting just nine races with Purex as his sponsor. The team suffered several mechanical failures and Speed only managed to have a best finish of eighteenth in the final two races of the season at Phoenix and Atlanta.
