It's really easy to pull the ECU on this car, the 6 cables are right under the cover and the ECU slides streight out. I had my ECU unlocked and was able to flash the latest ROM version with Mhd.
I have this extra low profile jack, It clears my car that is lowered on the HKS Springs to the preset; about 1" front and rear.
Enough space for a adapter puck and 1/4" of clearance.

Check your ride height sensor arm, it probably got pulled out during the install. They're mounted on the chassis side connected to the lower control arm. On the driver side, front and back.
Mind had a minor creak when turning the steering wheels at low speed too. Try moving the included rubber spring silencer on the front spring towards the end of the spring, there should be two on each spring. You should be able to get to them by just jacking up the car.
Most of the ones that have failed are on previous iteration of the b58 which had a different charge pipe design. The newer revision on the Supra and z4 is a bit more substantial so you'll probably be fine for a while unless you're pushing alot of boost.
The center section there the lug goes is also different on the ultras.
Ultras have a deeper squared profile where the other models have a shallower rounded profile.
I think the spokes on the ultras also have additional side machining for weight reduction.
You can re use the factory stem but they're this weird grey color that really stands out on Matt black wheels. The stemsaftermarket stem are just black and metal.
Nice, i have the same wheels, waiting on all black center caps.

These all black valve stem works with factory TPMS
I already have the Akropivic Evolution Link pipe on my car and its causing a bit of drone with my Catted downpipe, I am looking for something that is resonated.
The only option is to either weld in some resonator in my link pipe or go back to factory, which is why i am looking for some factory...
That's unfortunate, I'll have to send this out to get it bench unlocked. Any recommendation on that?
Or should i just wait on mhd to figure out how to break these? I don't mind waiting a few weeks, can't really go anywhere anyways
