4.30 vs 4.56 gear

While Fishmen is correct, it depends what you want the car to do.

If you lean towards running 660 then slap the tallest tire you can, paired with the deepest gear set you can run with out blowing the hides off- Then become ok with never driving on the HWY and just have a super fun car that kills at stop lights.

Or rethink what you want the car to do and build accordingly.
Lol. Very try. I do have a nx single plate with 175 pills ‍♂️ I know I’ll kill it with the steep gears. 175 shot. All roller big block. Flashes at 3800. Nx ez maximized lol it’s already a blast fun car. Genuinely having a hard time deciding if I want to take the 660 a bit more seriously. I live 45 mins from a real nice spot in central cali. But now everyone is running660 and I kinda wanna try that out lol. ‍♂️
