**Thanks for all the response! Helped alot. Another question I have is:

How do I really know / confirm my 2005 G35 Coupe have a sport suspension or not. Will the VIN be able to tell me?

Also, the car has 155k on it -- driven mostly in NY/NJ --- should the springs be changed? Only reason is because I heard the sports suspension -- is mostly related to the spring.

Thanks,

 

Is it AT or MT?

 

it's AT

 

Then no sport suspension.

Doesn't matter at this point anyway tho. Those parts are well worn. Changing the springs could be a benefit considering mileage, but I wouldn't go with stock. Go with something a half inch or an inch lower.

 

any recommendation? But if I change to KYBs -- they will ask if I have sport suspension or not. I always thought the 05 AT sports package came with the sports suspension. *THANKS

 

So all 05 AT Coupe = no sports suspension?
