I have a full weight 2010 GT with a 2.66 first gear T56 mag. 3.73 differential gears and something over 500HP. Using 28X10.5 MT ET Drags the diff. gears need to be changed. I see 4.10s are very popular and Ford brand gears are an easy choice. On the other hand, 4.30s are doable within my RPM range and could help the car out of the hole. I have set up Ford Performance and Yukon brand gears before but nether list 4.30. Any recommendation on ratio or brand for the 8.8 will be appreciated. Please don’t tell me to change the tranny.
