Leamington spoilt Racers first home pre-season game despite going behind to a great strike from Brown.
Racers manager Heydon was without several first team squad, including Wade Malley and Jordan McKenzie, which limited the fire power against their high flying neighbours.
Leamington's Obeng saw an early shot cleared and a Racing shot should have seen a penalty given for a clear hand ball but the referee played on.
Leamington were then awarded a penalty after a poorly timed Warwick challenge but Rowes poor penalty was well saved by Leamington old boy Caviezel Cox.
Racing Club then stunned their visitors by taking the lead in the fixture for the second year running, a screamer finding the back of the net off of the underside of the crossbar from Brown.
An Edwards’ deflected shot equalised soon after however and the 1-1 half time score was probably a fair reflection of the play.
Magunda scored an early second half goal with a tap-in and Baker-Richardson missed a sitter from close range, heading wide but made amends soon after ,scoring the third with a header.
Moore added a fourth with a strike from the edge of the area but Racing Club rallied late on with excellent combination play seeing a Jamie Vadasz shot well saved before Junior Bennett's half volley was parried out by the keeper.
