    Our extensive knowledge of Ferrari and Lamborghini both antique and  late model makes these our specialties.

    Here at Circle Performance there is no such thing as an un-repairable or unavailable part.  We will make it, repair it or have it reproduced  if any piece is no longer available to complete your job.

    Our outlook on rebuilding troublesome engines is to find there sore spots and make them less prone to repeated failure.

    Any rebuild we do utilizes the most compatible materials to work with modern fuels and oils to maximize it's service life.
