Well, I've been deciding over a month on whether to get a 335i or an is350. I think I'm going with the is350. I need to know what you guys think are the best f-sport performance parts are.

Well personally I would recommend the F sport intake and exhaust but it all depends on your preferences (sound, power gains, etc).

Im sure other members would suggest the sway bars tho. They seem to be the "must have" mod

Good luck with your choices, cant go wrong with Lexus

Yeah, I think my first two upgrades will be the exhaust and the 18 in spider rims.

you should do sway bars and springs/shocks first or coilovers if u prefer them over springs/shock combo

Sway bars would be good... but I feel like I really want those rims first. Then, I'll get sway bars.

how about coil overs + rims? do cosmetic mods first then performance, better than doing half and half

NitrousNik

I'm thinking more along the lines of the Vline led strip, how does that sound?

sway bars are by far the best f sport mod. The second would be the exhaust, quite a nice exhaust note

I'm in the same boat. Do you guys get f-sport sways or are there any other aftermarket sways that work well also?

There are the Hotchkins sways but they're expensive.

Someone posted a write up on import tuner magazine for F-Sport Parts on IS250. They should be similar to IS350 in some respect.

The F-Sport Intake has the best bang for the buck... gain of almost 5 HP for $500.

F-Sport Exhaust will improve by 1 HP but costs over $1000. < You're getting this mainly for the looks and sound.

You can also choose other intake such as Joe Z Intake Pipe and drill holes into the lower airbox, the gains should be similar but cheaper than F-Sport.

The intake gain won't make night and day difference in performance, so it's arguably a sound mod.

But the Rear Sway Bars on IS350 will make night and day difference in terms of cornering. A lot of members on here will consider that as top mod for IS350.
