The OP hasn’t been back since posting this thread. I wonder what path he’s chosen to go down.

I am currently breaking in my Calimer Stage 3, and have nothing bad to say yet but haven't beaten on it yet.

They already had my case so it made sense having them upgrade (after I dropped 4th gear) vs getting a T56.

Welded shift forks in the MT82 transmission are significantly stronger than factory non-welded forks, transforming the weak point of the transmission into a robust component capable of handling high-horsepower, high-RPM shifts. While specific percentage increases in strength are not typically quantified in public, welded steel forks are widely considered the necessary standard for high-performance builds (600+ HP), often replacing flimsy cast aluminum forks that are prone to bending or breaking.

Key Strength Improvements
  • Preventing Failure: Welded forks (commonly the 5/6, 1/2, or 3/4 gears) are designed to stop the bending that occurs with factory cast forks during aggressive shifting.
  • Upgrading Weak Links: The 2018+ MT82-D4 models are noted for having weak cast aluminum forks. Upgrading to welded steel forks, or aftermarket billet forks, is a primary recommendation for durability.
  • Added Reinforcement: Welding usually involves adding reinforcement to the fork structure, which, when combined with bronze pads, removes the risk of the fork breaking under heavy stress.
  • Better Material Base: Upgrading or welding 2011-2017 steel forks is often preferred for superior strength over the 2018+ cast aluminum alternatives.

Related Upgrades for Maximum Strength
  • Bronze Pads: Replacing the plastic shift fork pads with bronze pads reduces wear and increases durability, often done in conjunction with welding the forks.
  • Billet Forks: Many tuners (like Calimer) use billet forks instead of just welding stock forks to achieve a near-indestructible setup.
  • The "Whole Picture": Welded forks are often not enough on their own. For high power (600+), it is recommended to upgrade the clutch, use bronze pads, and in some cases, use a "shot peening" process (WPC) to harden the gears.

When properly built, the MT82 can handle upwards of 700-800HP, with extreme cases rated over 1,000HP when using billet components

I have a 2015 GT and I just installed a stage two Camimer in mine I ordered it, and it took three weeks, I am now sending my old one back on Calimers dime. If you go with the other T56 you have to change your drive shaft it not a direct fit like Calimer. I paid $3857.00 shipped to the door with the Mcleod braided hyd. line. And I will get back $500.00 for the core (old transmission) they will send you the label. I looked at all the other transmissions, and the cost was a lot more. $8000. Plus, the new drive shaft an extra $1000.00 If you plan on putting a super charger or twin turbos you might want the T56 but if all your power is going to be bolt on the Calimer is a great transmission for the money. They also build stage 3 and 4s to handle blower power cars. Stage two is still a 23 spline input shaft the 3 and 4 use a 26 spline input shaft. For your clutch information. I put in a Mcleod twin disc ceramic clutch with aluminum flywheel and replaced the piolet bearing while I was in there, as well as new flywheel bolts. I also have the Barton industries short throw shifter.
