Gears worth it?
Ive got a 2000 FRC mods are.
-American racing Long tubes
-3" X-pipe
-Borla Stinger axle back
-short throw shifter
-some sort of air intake (was on the car when i bought it)
-small cam
-2 stage nitrous kit, total of around a 200 shot
Also this is my daily driver, ive been told with gears my MPG wont go down to bad if i can drive it right. I dont really know what gears would be the best ive been told 3.90's, what are ya'lls opinions?

For your FRC, 410's would be perfrect for a NA car!! It might get a bit "squirrely" (sp?
) on the squeeze!! Several of my friends have 410 H/C cars with the MN6, and they absolutely fly!!

oh and the reason for 4.10s over 3.90s in your car is because the tranny is geared different in the frc than in the z06. you would have the same effect as putting 390s in a z06 when you do 410s

When I had 392/376 at the wheels, the 4.10's were great but when I went to 443/392 at the wheels, the gears were too much. IMO the NOS would be too much with the 4.10's. If you were NA, the 4.10's would be perfect!

I've got 400whp and 4.10s in my M6 C5 and after installing the Nitto 555RII DOT radials I barely spin the tires in first, and only chirp a little banging 2nd. I feel like I could add another 50hp to this and still have adequate traction with those tires...
BTW - I didn't notice any MPG difference going with the 4.10s... Mainly because I would skip 2nd and 4th all the time...
I say get em. 3.90s or 4.10s, you'll be happy... they're a serious SOTP improvement!

Well, I dunno about "Too Much" just means your tires weren't good enough... lol

if your not hooking with 4.10s with less than 400tq, your not using the gears right. You cant smack down the throttle, just lean into it and let the gears work for you. im 439hp, 402tq, and i hook well with plain jane Kuhmos

chad is right on this one. with your frc this would be the route to go. and your mpg may drop 2-3mpg at most. most go 3.90s to tell you the truth though, but what fun would that be.

MN6 gear ratios matches perfectly with the 4.10 ratio..thats why the car performs outstanding with 4.10s and still gets 28mpg on highway it will put the motor in its powerband real quick!
