it's TCM

Javelin tyre widths correct at 225F and 275R? Looks understeery just from that unless it's a typo and should be 255F?

Mikey,
Dewy and I are running the 1970 Chevrolet Camaro Z/28. I just built it and there is a slight problem. I keep coming up with a PI of 561 not 551. I have rebuilt it twice with the same results. As far as HP/Torq/Lbs, it is exactly what you have for the build.

Might be a slight typo with build as I also got 561 with the Challenger and the Cuda.

I can confirm it should be 561PI. Mikey posted it as 651PI at Ax4x Website as well. Maybe he forgot how to use a keyboard

Sorry for the typo. It happens when the desk is too dark to see the keyboard.

That being said, I may need the "elderly" keyboard, the one with huge keys.

When build with the same tires as the others, it was down on power but unreal in the turns. I took some grip away, and added a few HP with the extra PI. This slowed corner speed slightly and raised actual speed a bit (although the Forza Speed numbers remain down, due to stupid default final drive) to bring it to midpack laptimes at most tracks.

Ponty Trans Am weight for me with all required parts added totalled to 2,849 lbs. yet it states other wise above?

My Pontiac weights just over 3000 lbs. Are you sure its the 1973 and not 1969?

ok something is wrong

with the Cuda, i have 441 HP, 508 ft-lbs torque, 7.0L engine BUT
2926 lbs (instead of 3096lbs) and I'm at 456 PI
HELP
