4.30 gears with T-5

[6T9PONY]

Yeah, I'd say 4.30s are probably too low for your mods. If you didn't have as much power as you do, then they might be all right.

With a C4 you would probably be ok. The only thing you'd have to worry about is taching out before the finish line. Remember C4s don't have an OD like AODs do. Just 3 drive gears.

I do think that 4.30s are too steep for your set up right now. And someone else will have to tell you what to do about the C4.
