Moroso trick rear springs for daily driver?

..from Jegs..They're suppose to replace stock springs without stock height change?The 92 Gt's rear is sagging from age,(kinda like me-ha)..I've got a Moser rearend-spool 3:55.So,I'm used to sorta a rough ride.Jegs says"not for street use",but everything states that.Would these be OK?I like how one spring is stronger to compensate for the "side" launch problem...I haven't bought them yet,just looking..I'm building a "street machine" from the rear forward,ending with a 350 hp crate motor when the cash is saved....Thanks for any advice.
 
I'm pretty sure they are drag springs. Do you have drag springs in the front?

BTW, good adjustable rear shocks can also be used to compensate.

I've tried the drag setup, and prefer handling springs for street use.
 
Shock won't compensate for the sag, but it will compensate to keep the car level under full throttle.
Strange and qa1 adjustables.
I like the eibach pro lowering kit. Decent ride, better handling, nice stance.
 
The moroso springs will bring you back to stock ride height. Many people use them in their daily drivers. If you are looking for a lowered stance Eibachs are great. But the answer to your original question is yes, they will do what you want them to.
