Did you buy or build your roadster? What make is it / how old is it?

Are they squeaks like control arms / joints? or squeaks like panels rubbing?

If they are joints / bearings, check that they are sufficiently greased (if the car is older, maybe it needs to be serviced) or replace any worn items (ball joints).
If they are panels rubbing, look for shiny spots and apply some silicone or possibly replace a loose rivet.

Can you replicate any of the noises as it is sitting still and chase them down?

More detail, would help. Good luck
