Swapping gears
Hey Gents. I own an 05 A4 GTO with a blower, cam and headers. { 485 rwhp and 458 rwtq } Stock 346 gears.. My friend owns a 04 M6 GTO with 373's for his gears. He wants to swap his 373's for my 346's. He wants to go back to stock. Is this swap possible ? How much if any will I benefit. Pro's and con's.....Thanks.
