Apparently the car I bought has them according to the original owner and yes, I am embarrassed to admit that I have not looked to confirm it until today. The car is definitely lowered and the rear springs are lime green. The owner said he installed them and the springs a long time ago in the late 90s he thinks. It sits nice but I am wanting to raise it up a little. I'm thinking about some stock height front springs and maybe some Eibach Pro-kit rears? Not real sure what to do at this point.

 

Yes, those look like Belltech spindles, so your front springs are probably still the original springs. The spindles lowered the front, not the springs; that was the point. The factory springs might've sagged a little over the years, so brand-new ones might raise the front a little bit. But I think most new springs you'll find will be considered "universal" and might be too tall.

You might be better off looking for factory front springs that are taller than factory IROC front springs, like from an 82-84 Z28. They'll have probably sagged a little, but your original IROC springs probably have too, so the Z28 springs will probably still give you a little lift. Or try some rubber coil spring boosters. Or leave the front as it is, which might be best.

Edit: Or return all of it to stock and sell the Belltechs to me

 

man that stance is about perfect

and as LAFireboyd stated, they are belltech drop spindles. I have a set sitting on a shelf

You could try swapping out the shocks and struts to see if new dampers would help stop the car from bottoming out.
