sorry to bring this thread back to life yet agian but, im getting my Z -H techs installed next week and want to know if i should use my stock sport suspension shocks or my friends konis? hes giving them to me for like $300 but thats $300 more that i need to spend.. anyone???
will they need to be replaced anyways?

 

Given what is in your future, pass on the $300 Koni's even though that price is a steal. Invest $500 in D-specs when the time comes where you get around to buying 350Z S-tech's down the road. As of now, in spite of Koni's having better valving, 350Z H-tech's will not overwhelm your oem sport shocks so I can't sit here and tell you that you have reason to spend $300 on the Koni's.
