Newbie is a newbie

Just F Me

Word of advice since you're new to the forum...
Perhaps you should have said ..."I read in car and driver that 2011+ models got suspension upgrades as well as torsen LSD...is this true?" Instead you come out and straight up say "_________________" .

Not sure how old you are...most of the IS F members here are older, somewhat more mature (excluding me, I'm 14). A lot of them have had their cars for a few years and have been on this forum a lot so generally they know what they're talking about.


A lot of car magazines are idiots. You can only take so much from it. Perhaps since you're new to the forum, might be good just to lay low and read for awhile before you come out and say with 100% certainty before you state something.

BUT HEY! Now you know 2010 on up got suspension upgrades as well as an LSD.

You're not mistaken. The Torsen LSD was first installed with the 2010.

This thread is ridiculous and has given me my biggest laugh yet today...thanks guys. It is always fun listening to uninformed people have it out with informed people with a chip on their shoulder...lol.

Agree. And my thought is that the OP's issue is more related to tires than anything else. When I take off from a stop I always roll into it a bit rather than just stomp the accelerator.

OP must be like WTF.....I asked a simple question and now people are arguing about when the LSD first came out?!?!?!

I checked the tires and they are still good. Haven't checked tire pressure yet, but I did an alignment a few weeks ago and tire pressure were all up to 35 psi.

I also meant 20C as i'm in canada :P haha

Check for a blown shock. These cars are pretty stable off the line even when you punch it, so I'd be looking at the suspension components to be sure nothing is bad or weak.

The Torsen LSD was a change for 2010. The eLSD works pretty well but does not work under 15 mph, so it won't help with a launch. Do the pedal dance if you want to see what open diff really means. Also, we have "pretorque" washers in the spider gears of the open diff on the '08 and '09 which makes it behave more like a Phantom Grip than a true open diff.

Check your tire pressures, be sure your rear toe is correct and thrust angle is as close to zero as possible. Check your shocks to be sure they're not leaking (excessively), and if all else fails, corner weigh the car. It's possible the springs are a bit off from the factory.

Man, it would be cool if you could walk us through those steps and hold my hand. lol

thanks for the leads, lobuxracer. It's still a mystery to me, it might just be the tire pressure, or the crappy uneven road surfaces we have in Vancouver. I don't suspect the shocks, as I just put in new BC coils, and rear toe and thrust are pretty much 0 according to the alignment readout.

You might want to have the springs tested. Very few aftermarket springs are well matched. This is why Hypercoil is the racer's choice. They deliver as advertised. Most of the others are +/- 10% (or more) so you could have wildly different spring rates.
