You won't be breaking 5 speeds at anywhere near the power levels you do in a 3100 lb, RWD Subaru.

If you're making "tons of power" in this car, then I think you can afford the solution- PPG!

Yeah PPG 5 speed and front LSD makes a lot more sense than an STI 6 speed to me. You would be shifting way too much in a 6 speed I think. But hey it's your car, build it however you want.

Well I have been tossing around the idea of buying a kit and building one up similar to my wrx. But I know a 5spd, wide sticky tires, 500whp 35r is going to break a 5spd. If the skid pad numbers are correct that might also oil starve the 5spd and the motor. But least the older six has the oil pump and you can dry sump the engine.
And for the record.... my 5spd lasted 100k miles at gt30r levels. I know a lot is the driver. But this car has some potential. |

With no resistance, the gears don't take the same levels of abuse as they did in an AWD and ham-fisting. --kC |

I broke my 5spd at 220 lb-ft (very low reading Mustang) in my 2600 lb Imprea L when I was RWD. I actually broke my 4.11 and 4.44 rear ends first. When I went to the 3.9 r180, second gear gave up.
I was on 215 width Azenis...not the most tractive force. |

You launch a car at a autocross lets justsay.. The load shock is going to eat that 5spd. The resistance goes up with wider/sticky tires. And the load goes up on the gearbox. So where is the fuse in the system? Axle or Clutch? We still have not addressed the oiling issues of a car that can pull 1.8? g's The 5spd is going to have oiling problems, The 6spd 04-07 has the internal pump. And the engine can be dry sump. Anyone that buys a stock bugeye donor car to build this, is going to get screwed on the glass gearbox 5spd. |

Didn't blow up anything. Never hamfisted/jammed gears either. Never had an issue and the owner after I that still has the car, hasn't either. Said it still shifts like new a few years ago. (And he bought it to autox, knowing its history, but then got into karting). --kC |

So how does the center/front dif work on this car? The center diff locked to run 100% power to the front?

However I was also pointing out that shorter final drives reduce the torque loading on the trans. |

Not sure why you would spend all the time building a car from a kit form to put a weak gearbox in. I'm surprised F5 has taken this route. As if 5spds begin to fail, It will only hurt their product line. And if 70 lbs is all the weight gain for having a reliable gearbox. I'll take the 70lbs. I can easily get the back in other areas anyways. Wheels, Flywheel, Seats and a Diet.. I'm just saying its not the best route. And like myself and a few others that have made a 5spd last... The guy off the street that doesn't know the history like we do is going to have issues. Even more so when the open diff is swapped out. I better start buying up 5spds for resale.. |

Your LSD argument doesn't differ from my scenario. I had a mechanical LSD in my car. Besides which, I'm in your corner. A stock 5-spd is fragile and oiling issues will need to be addressed. As stated, I'd still rather drop the getrag in there.

Well since the car doesn't with any transmission you can put in what you want.

Ffr wanted a single donor vehicle and a $15k pricepoint. Sti's are harder to come by and cost more. My 02 wrx has 188k miles with a vf39 and original motor and trans. My 06 had 351wtq and the gearbox lasted 50k miles with 4 years of hard launches with wide r comps. The 818 will be fine.

I would be concerned with the ease at which the tranny can be removed and repaired.
