[QUOTE="xblitzkriegx, post: 16332932, member: 105608"] Stock tires and 4.10s = 2500rpm at 70mph. 4.30s will be 2700rpm at 70mph. On a lightly modded car, you'll cross the line around 5500-5800rpm in 4th on 4.10s and around 5800-6100rpm with 4.30s. 1st gear mph differences between stock, 4.10, and 4.30 is 47, 37, and 35mph. Second gear differences are 79, 63, and 60mph. Seat of the pants difference between stock and 4.10s is massive but 4.10 to 4.30 isn't as big a jump. 4.10s will make the car feel like it gained 50hp+. Go with a speedcal. The gears get chewed up really easy as they don't last. The 23 tooth is used for the 4.10s but it barely lasts a year if you drive it a lot. [/QUOTE]
