I don't know which coilovers to go with since the v8 is heavier please help me out thanks

 

What V8 are you going with? What are you using the car for? The car will work ok with the standard spring 8k/6k rates, but I'd go stiffer in front if you are going for more performance.

As far as brands to go with, Fortune will give you custom spring rates and will valve accordingly. Their product is very nice for the price. I would stick with Stance, Fortune, or BC.

 

Or even parts shop max aka pbm. All great companies!
