Would a JB4 be an option?

Yes.

Another thing to consider is what kind of horsepower/torque that this new MT/clutch can handle. I'm assuming we don't have good information on this yet.

That seems right; we don't really know yet.

Just a JB4 added +40hp and +100tq on a custom 91 tune from @Jesse DaBears for me.

Weird thought.. Could I mount the stock rear tires (only 1k miles) to the front and buy some 295s for the rear or would there be rubbing? I'd imagine the traction and handling would be great?

You may rub a little. I've got the 265-295 setup and there's basically no gap on full lock when stopped (I'm also lowered on coilovers with an alignment, so there's that). I've felt rubbing on rare occasion. I think a 275 will rub depending on your suspension geometry.

I wonder if they'll put a clutch delay valve like how they do on BMWs, something to consider changing out if they do

No need for a larger brake kit. The OEM calipers work just fine with upgraded pads and fluid.

I agree. A BBK would probably come after the tires, suspension, aero, and pads + fluid, considering cost as well.

PSS and PS4S will get you about 2-3 sessions before they get greasy from my time on the track. Wider tires did offer a bit less tail happiness along with my alignment and corner balancing. I would go for track tires if the Supra was mainly a weekend and track toy -- they would get me a few more sessions.

I have a 2021 Tunable with a brand new Akroprovik downpipe I'll trade you for the A-91 Mt. Plus cash obviously. Assuming you're interested In the auto...

I'm running 275 in front stock suspension, no rub.

Thanks for everyone's replies. I'm pretty familiar with dialing a car in. I'm looking forward to the Supra MT and learning all I can here to make the car even better.
I'll order a JB4 and give that a shot after break in. I'll get some wheels, tires and pads going as well and get some track miles on it this Fall.

Thanks for everyone's replies. I currently track a 550whp 911 and have raced several cars in wheel to wheel classes in NASA for 10+ years. I'm pretty familiar with dialing a car in. I'm looking forward to the Supra MT and learning all I can here to make the car even better.

If you wanna be around 500 wheel, about where the stock turbo max's out, doing the unlock (not the full clone) running a software like BM3/MHD with e50 and a downpipe will get you there.

Thanks. 500whp is a good place, so long as it's not too peaky. I'm not opposed to a new turbo setup but only if i can run the stock ecu with a tune, don't want a standalone setup. I'll probably just JB4 it and wait for the ecu to be cracked. I'm assuming the new M2 will have the same issues and there has to be a lot of pressure on companies to crack these things.

don't want a standalone setup. I

There are no standalone setups for A9X's right now.

 

[XLR8]

Sure there are. You could run a Motec ecu and pull the bosch unit out completely. I mean if you wanted to lose all the creature comforts.
