My setup was cheap and not legit since I was in highschool and jobless

. Main reason being is I had stock 300ZX stock springs and struts up front, and believe it or not it road just like stock. Only problem is you're so low you can't adjust em unless you get Eibach sleeve coilovers. The rear I had no name sleeve and 300ZX struts and it road really stiff. Passngers up back would fly to the roof

.
Depending on your year of the Q you got the modifications are different. For the 90-93 300ZX/R32 Coilovers and Stock suspension fits but the front towers need the holes grinded a bit closer together. The rear if I remember correctly you gotta use the rear top mount or something? Thats for stock suspension, dunno about coilovers but I hear the R32 are direct bolt but I dunno if the 300ZX ones are. 94+ have different modifications if I'm correct.
I strongly suggest getting real coilovers from a 300ZX/R32/Q45. It'll save you the trouble and money in the end. I busted my oil pan and then it went all down hill from there after it fell off the flat bed lol. Good luck hope this helped a bit. Make a good choice and not just to save money or slam the car in a hurry.
Heres a picture of when I had the car with that suspension setup. Transmission clearance was like 2.5-1.5inch off the ground and oil pan was like 2-1inch I forget but it wasn't good.
