I think it just depends if your going to track your car. So I dont think its a MUST. IMO

 

anything that protects an engine from heat is a good thing.. being that now we have a intercooler blocking the radiator. an upgrade is a must in my eyes if your F/I is a daily driver.. on highways esp

 

Thats cool. Ill just stick with my stock one and water wetter for now. I was told by the shop I deal with in town that a aftermarket one was needed unless I track the car. He also said that there isnt one for the G and the modding it takes to get the Z one to fit isnt worth it. Its always nice to deal with a shop that trys to save you cash and not suggest you buy parts just to have them.

 

if you read the thread you would of seen that the PE radiator will fit and all you need is mounting brackets.. if you dont drive the car much and its mostly in a garage than yeah i wouldnt get one.. but i drive my car alot and the engine does get pretty hot.. funny my shop didnt want to do a radiator either because of the fabing needed to be done.. dosnt mean im gonna skimp on this..

 

Hahahahaha Does it matter how much I drive my car? When I drive it I DRIVE IT HARD! Like I stole it. You do what you want, its your cash. We all know I spend cash on crazy **** so I guess Im not one to talk. I just dont see the point.
