what Size tires and rims ? Do I need 18s? Or can I accomplish the same with 19s? Gotta little confused cause some dude at the top of the forrum said u need 18 in forged wheels or something to achieve those numbers. Do u have an IG by any chance ??

Tires will make as much, or more of a difference, based on grip and launch ability. A set of wider or stickier tires will be a more efficient way to add a tiny bit of performance, both in a straight line and laterally, than any wheel change.
But to answer your question: No you don't need 18s to make similar performance numbers.

so what else can I add other than the jb4 and e30 to see low 3.1 or 3.2 0-60 times ? Would Water meth injection help ? Would downpipes ? Can I even pair downpipes with the jb4 ? And can I still run map 2 if I’m mixing 91 octane and e85 to make e30. There’s no 93 in cali

Terry gave out a firmware upgrade few days ago. Pretty consistent results now in map 7. I am sure I can hit much lower when I fiddle my own map. But overall the car has gotten much more stronger since the update. Pretty sure I can improve my previous time with this. Will be pretty sweet to finally get into 11.4s by spending just 800 canadian dollars (500USD haha). Trap might suffer a bit, car has much better low end now.
PS: The time at the bottom are my stock times without JB4. I should also add that my car is pretty lowered (H&R sport springs is giving different heights to different people). So I have some excessive camber issues, (around -3.5), which really does not help with grip. Also my car is running on 19"s, which some of tuner's best times are not set on (usually super light 18s).

MBWorld Fanatic!
What mods will u be doing to the m340 to get it to the low 3s 0-60?
I don’t think it’s that much quicker than c43
im not c43 fan boy, it’s a great car and I love it but has its issues.
it seems to run faster times than listed in some articles
the fl top speed limiter sucks!!!
