Front drag struts

I am planning to install drag struts on my z28 and was wondering if I should go with 90/10 or 70/30. or maybe just go with coil overs. Does anyone know if the 90/10 is too soft for street use?

I wouldn't want to drive a car on the street with 90/10. Its rather scary honestly. As soon as you accelerate the front end flies up on you. Very bouncy. IMO you don't have a lot of control over your vehicle.

I'd say if you only put 3-5k on it a year go for it. espesially if you streetrace from light to light
