I am having a hard time deciding here. 3.73 or 3.90 with the car in my sig. I only drive it about 1500-2000 miles a year (5-6 months here in MI). And I have heard the 3.90's are noisy but I had a 3.73 Richmond and that was noisy and never bothered me. What should I choose?

 

Oh yeah this is for a 12 bolt too.

 

With the car being driven that few miles per year, why not go for the 3.90's?

 

12-bolt?! 4.10!!

But for sure, go for the 3.90's .
