My stock is350 is getting kinda boring.
What mod made your car more fun to drive or at least changed the driving dynamic?

 

Trading it for an ISF... sorry had to do it

 

F sport sway bars made a night and day difference for me

 

I have 3 mods that's handling/performance:
1. F Sport sway bars. This is the best mod; everyone with an IS350 needs to install this.
2. F Sport intake. A little nicer sound; very little noticeable difference.
3. Steering wheel weight/balance. Don't notice much difference on this one.

 

Sway bars, coilovers, and grippy tires. biggest changes felt. Then exhaust.

 

my is 350 came with an f sport exhaust when I bought it. I personally love the sound it makes. I can hear it distinctly even in the lower rpms. Im also considering on adding the f sport intake (supposedly makes the car sound even better).

 

also considering how everyone is saying that f sport sway bars is a must. I guess im going to have to install that now.

 

The only thing that would make my stock 2010 IS350 more fun is to buy an ISF and park it next to it

 

"buy an ISF Hurrrr durrrrrr" jokes aren't funny anymore

 

Thanks man, I'll was thinking about an intake...but if it doesn't make much difference if rather save money for sway bars

 

Rr racing tune is also a pretty nice upgrade

 

It wasn't a joke. That's my next car, if I can find a 2010 through 2012 with decent miles (80k through 120k). No laughing here. I like the IS350 exactly the way it is, stock. Let me take that back. I may look into F Sport suspension upgrades at a later time (I only have a bit over 60k on the odometer)

But if you are looking for a power upgrade, RR Racing has a Supercharger kit that will get you to 455 WHP with headers and an exhaust. Then you won't be bored for awhile

 

FBO+Tune makes the IS350 feel livelier, especially with the available higher RPMs from the tune. You'll also be able to break into the high 12s in the 1/4 mile which is pretty good for a NA V6 luxury sedan. Here's my run as an example:

Like others mentioned, suspension upgrades such as sway bars, coilovers, lighter wheels and a ISF steering ECU will add a significant boost to the fun factor to the IS350, especially with the platform having a decent curb weight and weight distribution.

 

That's awesome. Best I've been able to get stock is 0-60 in 5 seconds, which is not bad

Besides ultra high performance summer tires, installing an aftermarket Sparco racing seat was the biggest change I saw personally. The way the seat holds you in, makes you feel more confident in the corners and gives you the sense of being in an even smaller, go-cart-like ride.
