Are Replacement Hatch Struts / Shocks Necessary for New Spoiler?

jtt

Hello,

I recently purchased a genuine Nissan spoiler for my base model 370z from Courtesy Parts. Beware: spoilers purchased from Courtesy Parts and most dealers DO NOT come with instructions, the installation template nor replacement hatch struts.

My question is this: Are the replacement hatch struts really necessary for the added weight? Have any of you added the factory spoiler without replacing the struts? I noticed that many people selling the genuine spoilers on eBay are including replacement struts... it also appears that the base model Z and sport model have a different part number for the struts. If upgraded struts are required, can I avoid the dealer and purchase something cheaper that will get the job done?

I'm hoping I don't need the upgraded struts, because the dealers sell them for over $140 each, and I'm already $550+ into this spoiler... I can't return it to Courtesy Parts because I would have to pay a 20% re-stocking fee + $25 shipping. I should have just purchased the damn thing on eBay for $500 and it would have included everything I needed! Sigh...
