Every difference between the MT and AT

Right, it's due to the AT inability to launch at higher RPM. Like the others said, don't let anybody get you disappointed over an AT. Especially yourself, enjoy the car and figure out your own likes/dislikes. While the MT can launch better, neither car is really fast in a straight line so I don't really even pay attention to that. First thing I modified on my car was wheels/tires and suspension, nothing to do with power.

If you experiment with the car in the various sport and manual shift modes you might come to enjoy it a great deal... At the end of the day, the availability of final drive aftermarket options really should make you feel good as you can change that out and make the AT lower gears as aggressive or more aggressive than a MT if that is what you want from your car.

Cliff notes - the AT on this car is pretty darn good. Don't feel bad for driving an AT, experiment with the different AT driving options to figure out which you like best. :-)

If someone comes up with an aftermarket torque converter that has a higher stall speed, and retains the lock-up feature, the 0-60 will drop noticeably. There are respected shops that could mod a stock one. If my car was auto, and not a daily driver, I would have already looked into it.

MMM... lower final drive, higher stall converter, and a centri blower would be a nice combo on an auto.

A lightweight high stall lockup converter and final drive would really liven up the AT. I think the gearing in the AT may have been deliberate, can't have the slushbox outperforming the "proper" gearbox. I test drove an AT and thought it was nice and sharp, but couldn't justify the added cost. There are times I wish I got the AT and times I'm glad I got an MT.

Honestly 0-60 is a useless figure IMO. I may drive aggressive but I never clutch drop, I just don't see the point. Seems like you are just burning $ for no reason.

There's another thread on this forum that has lots of detail, but I can't find it. Here's a handy video though.

Seriously do not feel bad whatsoever for getting an AT, there are countless articles praising it. Neither is "better" than the other, it's just down to preference now and "right tool for the right job".

I drive an AT. All cars I owned before my 86 were highly modded Hondas. Nothing compares to rowing through the gears powershifting! When I got the 86, I got the AT because when I test drove the paddle shifters, I was amazed with the responsiveness of it. Plus Philippine traffic is a bitch if you don't already know. This car is my daily driver, and I don't miss stepping on the clutch while stuck in traffic.
On the track however, I wish I had that third pedal. I have already done the final drive mod (4.556) which helps a lot, but powering out of turns with a torque converter just sucks compared to a high performance clutch. You do however have the consistency of shifting. I've seen a lot of MT drivers miss shifts on the track.
During our Dyno day, the MT cars had a 10-15whp difference on the AT cars. Until we get that high performance torque converter, that will be the glaring difference between transmissions.

My reason for buying MT was the ability to simply swap in a stage 2 clutch when making more power. I had a AT truck and I know the cost wont be the same but I was kicking my self after burning the 1st and 2nd clutch packs out.

I owned an AT BRZ Limited for over a year and loved it at first, but then I got more serious about autocrossing and realized it was holding me back. The longer gearing, the less responsive torque converter, and the inability to perform decent launches were beginning to cost me in a sport where fractions of a second can win or lose it for you.

I experimented with brake torquing for better launches but that only helps so much. In addition, I researched a couple of the options for a final drive change, but such a modification would be fairly expensive and would also put me in a ridiculous autocross class.

I had a friend that let me autocross his MT FR-S a few times and it was clearly more peppy and could really dig out of low speed corners/transitions much better than the AT. Yes, you can easily downshift the AT to 1st in those situations, but the times that was advantageous were rare and having to shift back to 2nd will cost you a little time.

Now, for HPDEs and other non-competitive track days, I think the AT is great. You obviously don't need to launch and the paddle shifters will probably move through the gears more consistently and faster than most folks can do in a MT. The daily driving aspect of an AT is nice too. Stop and go traffic can get annoying in a MT and it's convenient to be able to hold a coffee or beverage in one hand while you're moving from stoplight to stoplight!

In the end I decided to sell my AT BRZ Limited with 11,000 miles and get a used MT FR-S with 260 miles and was able break even. The extra features of the BRZ Limited were nice but weren't critical and only served to make the car heavier for autocrossing. I'm very happy with my decision and I've definitely closed the gap on folks that used to beat me in my AT BRZ.

Had I not got addicted to autocross, I'd still have my AT and love it. Once my autocross skills progressed to the point where the AT/MT differences started to matter and I realized I could break even financially, I decided to make the swap.

Even if the MT is slower than the AT, I'd still get the MT. This is purely a toy car for me.

The 4.556 FD made a good diffrence is the shift points of my AT. Almost the same as MT in 1-2-3 gears. highly recommended.

Heres a review of the BRZ AT with some numbers to compare to the MT

Me and a friend ran his stock MT FRS against my Auto with injen intake and greddy evo3 exhuast..

I'm recording, the red FRS is MT

Well that's disappointing footage lol. It's whatever. Not like I race anyway. I think I just need some more down low torque. I think ill be happy with the FA20 stage 2 I've been looking into and just go with cosmetic mods for the life of this car. Track days hopefully that's for sure ide love to learn. Only time will tell. Thanks for the info!

What all do I need exactly for the FD? There's more to it then just buying the "final drive" correct?
