Default 2010/earlier vs. 2011/later question

Hi guys,

I've read that there were some significant suspension changes in the 2011 and later IS-F model. For those of you who have driven both, particularly on the track, would you say that the difference really is significant?

And- if so, is it anything that couldn't be accomplished with some suspension mods on a 2010 or earlier model, perhaps for less money than a newer model?

Thanks for the info, great to be here!

I personally haven't driven a pre-updated IS-F but from what the press/auto journalist say, the difference is pretty huge. I mean an updated 2011+ IS-F is faster by 8 seconds around Virginia International Raceway, 8 seconds per lap is pretty significant.

That's stock for stock though, I'm confident with the right aftermarket parts you can make an 08-10 IS-F own a stock 11+ IS-F. I'd say start with a real LSD, that seems to make the biggest difference. You won't go fast unless you put the power down right?

The torsen LSD was added in 2010. The suspension changes in 2011. Get at least at 2010 if you can to have the updated LSD.

What kind of LSD did they have before 2010?

No mechanical LSD before 2010. It was an "ELSD", basically just used the ABS and VDIM systems to try and replicate a real LSD.

2011 is better than 2010, many other small interior upgrades too that add to the value as well as a new steering ecu, not to mention thicker steering wheel, etc.

the diff is significant, especially on track

When I was shopping there was a substantial increase in price once you go 2011+ but I think it's well worth the premium.

Just like Carlos Lago from Motortrend said about the updated IS-F, it went from being underdog to front runner with the updates in 2011+.

Before the updates, it would always be playing catch up to the M3 and C63 on a track, now it runs head to head with the M3 and circles around the C63.
