Police say the thieves removed a fence panel between 1.20am and 2am to gain access to the compound where they stole the 18in diameter wheels.
Police officers would like to speak to the driver of a white Vauxhall Corsa that was seen outside the premises just prior to the break in, as they may have valuable information.
The the night before someone cut a hole in the fence at Bury St Edmunds Audi to steal a 155mph RS4 Quattro Avant.
