This coming spring I'm doing a few mods and need some advice on some of them. I'm definitely getting 18x9.5 Z06 grey wheels with Nitto or Toyo tires. I'm also definitely doing some suspension mods (Bilsteins, Pro Kit, subframes, LCA's, relocation brackets, adj. panhard, and sway bars). My biggest problem is money, like most of us . Now these are my two options:

1) FLP headers and 3.73 gears with a new differential cover

or

2) 12 Bolt Rear (Moser or Strange) with a very very small chance of having enough money to get the headers too.

Also, should I port and polish my stock throttle body of get a new, bigger one??

All help is greatly appreciated!! Thanx

 

Id go with the rear if you are M6. Too many people break the 10 bolt before they consider buying the 12bolt.

There is no point on getting the larger throttle body. Just port and polish the stock.
