so i might be getting coupe sport suspension and putting them on my sedan, only thing is the seller isnt including the bolts, can i use the bolts from the sedan suspension to mount the the coupe suspension?

 

You can use your bolts. The suspensions on the Gsedan, G coupe, and 350Z are essentially the same with some exceptions depending on the car: some sway bars are stiffer than others, some springs have higher spring rates and are different lengths, and shock valving and lengths are different.

They all bolt up to the same locations with the same bolts.

 

would i have to revise the springs?

 

Do you mean the shocks?

 

yeah whichever it is. hahaha someone just tell me everything i have to do.

 

If you have the standard suspension the coupe sport springs will make short work of your shocks/struts. If you have the sport suspension, it will last a while, but it depends on how you drive. You also have to determine what shape your shocks are in now. If you have alot of miles they might be ready to be replaced anyway. Once you have determined this you have to ask yourself, if the shocks go out in short order is it worth it to pay to have a new set installed or would it have been better to have replaced them in the first place? Once all of this is installed you should have an alignment done, after a week or two of driving.

 

well the seller is including the coupe shocks with it its basically the full coupe suspension. ill only be riding on these for alittle probaly for 3 months.

 

^Your bolts will work. Change shocks and springs out at the same time.

 

the coupe suspension that im getting comes with shocks and springs, would i have to worry then about my shocks blowing?

 

Not unless they were blown when you bought them. How many miles are on the suspension? If it is relatively low you should not have a problem with them.

 

the seller said 110k but 79 ca hwy. would those last me for another 3 months?

 

I would find out how much it is going to cost to have them installed and weigh the cost of new shocks vs. cost of installing separately.

 

im actually installing myself well with a friend of mine.

 

New shocks = new shocks. Shocks wear progressively from mile 1 by 4 years or 60k rebound control [stiffness] is usually half brand new rate. The problem shows up on rear first since the rears start out stiffer in rebound.
