i dont believe the springs would be to hard to put in. i would have it professionally done though. should take 4 hrs at the most. i wouldnt pay more than 250 for the install though. heres a link to another thread. hope it helps

I got my 350Z springs and struts off a member on my350Z.com The member name is Lotus, very nice. Not just because I got a good price either. I paid $150 shipped. Ironic thing is I still have a extra set of 350Z springs sitting in my garage.

Here is a link to the post I did where I review what the 350Z springs and struts did for my car. Their are lot's of really good benefits, but some bad things that need to be thought about by anyone thinking about the swap.

does the coupe have the same springs as the g and the struts are just different or are the springs different as well. if the springs are the same could you just get the struts and have the stiffer suspension or do you need to get the springs as well
