I know that there are Strange adjustable rear shocks for these cars, but I have not seen Strange coil-overs. When I talked to BMR about this, they recommended the Strange shocks + BMR springs for a drag setup.
Most guys using QA1's with Cobra Jet springs. or K springs with Tokico d-spec struts and shocks. I like the low and flat look, so I went with H&R super sports and Tokico D-Specs
