M6 or M12 for Road Racing and FRC?
Well.. I've been bitten by the Road Racing bug!
(I can still see the mark!)
I haven't decided whether or not it will be heads, cam or maybe even a stroker motor.
I want to upgrade my transmission as well and I plan on keeping the stock 342's.
I'm going to have an RPM transmission installed. Would I be better off with the M6 or a close ratio M12? I'm not opposed to putting in GForce 5th and 6th as well.
Thoughts?
Thanks in advance!

I am no expert but I would keep the M6 and spend all your other money on seat time , brake pads, fluid and the rotors you will go through. Head, cam stuff is great but, get really good at driving and have good brakes. The car is pretty fast as it is. Did I mention the seat time

Yeap. I'm definately going to be getting seat time.
I have to replace my trans anyway and it won't cost me anymore to go with the M12 so I was wondering which one I would be better off with?
Thanks!

Dont do any if any at all HP up grades for a long time. Seat time and more seat time is the best OPTION.
When you do any upgrades start with the contact patches. Brake Pads, Rotors, brake fluid, tires, seat & harness system.
OK maybe an oil cooler and transmission cooler too.
Good Luck

Hi Tom,
I have to replace my transmission anyway.
And assuming that I later have some nice HP #'s, which would I be better off with? M6 or M12?
Thanks!

The "standard" 6-speed has closer gear ratios in all but 5th and 6th, and unless you anticipate changing to a lower rear gear, you will seldom use 5th anyway (unless you're cruising)
Randy, tell us more about changing the 5th & 6th in MN6's. I sort of though you had to swap out everything, but I'm not a gear man.

A number of TCC racers run the M6 trans and 3.73 gears, maybe the tracks in the midwest are set up that way. At the various tracks I have been at where they were running, it sounded like they were in the middle of the power band coming out of the corners.

I am with all above.....seat time, seat time. I switch transmissions depending on the track, but have never switched final drive ratios and i have been happy.

4th is one-to-one in all the OEM trans....do they change it????
I loved the GM racing trans. I could use 2nd-5th at a track like Rd Atlanta, where you may only use 3-4 in a street trans. Too bad they were so expensive, and too bad they are all gone...
Since I'm running a stock LS1, I run out of steam low in the rev range, but I still like the ability to use 2nd at low speed corners (with the MN6) vs having a tight 5th gear.

Dave,
I put a M12 in my coupe (because it was what I had in stock) with 3.42's and I regret it. Not so much at Watkins Glen, but at Pocono there are times where I would have to drop to second in traffic at devils elbow or when running the double infield, the turn going into the straight away, and I would run out of gear in a split second. It almost felt like I was neutral reving it.
As far as extra power, the other are right as far as seat time goes, but if your going to run Pocono a lot then the extra power is needed. The reason is because Pocono's straight aways are so long that if you get caught up in traffic, that cant drive... they will slow you down in the twisties, then give you the pass on the straights, but not let up. So if you cant out power them, your stuck slowing down on the in field. That gets old fast.

That's what happened at Pocono and it was pissing me off! I was faster than a few cars in the twisties but I couldn't pass them in the straightaways.. I'd like to remedy that situation!
I think I'm going to sign up for Lime Rock on June 21st, will you be there?
(you didn't look to happy in the morning at Pocono...)

I just put a Stage V RPM MN6 in my son's FRC....on the shorter tighter tracks I do like the MN6 better.
Hopefully by this weekend it will be ready to test drive.

I love the Wilwoods setup from LG for the fronts. I run the factory on the back.
Wilwood pads all the way around. The fronts are so thick I think you can run them for years. Maybe I don't brake deeeeeeeeep enough
I did do the DRM master cylinder and what a difference it makes.
BRAKES are ROCK solid
