The ASRF TAC, State Rego authorities and engineers have lately been looking very closely at the quality of the critical suspension parts used in Street Rods.
“Unsafe parts (for example as SG Iron Spindles and Perch Bolts) and issues with SG iron beam axles are forcing the ASRF and other signatories to monitor what we approve much more closely. Most suppliers here and overseas offer excellent products, but some do cut quality to keep prices down,” confirms Peter Koning. National TAC Coordinator.
“TAC’s or Certifiers might not accept some products without test reports from the manufacturers or the car builders. Therefore, we highly recommend you consult with the people who will approve your car. They may have a list of accepted brands or might have concerns about others. Swap meet parts are often of unknown origin and might be rejected or need testing, so be careful if buying used parts.”
A final point of note is that some States have stricter rules than others, and should you one day want to sell your car interstate, it would be best that the whole history be available. Otherwise anything suspect might need special testing or replacement and affect the resale value.
