Which F-Sport should I get installed first?
Spring is just around the corner. I have an IS 250 AWD. I would like to make some modifications to my suspension but I'm not sure which one to go with first. Should I get the F-Sport springs/shocks or F-Sport sways? Anyone have pictures of the F-Sport springs on an AWD with 17" and 18" tires?

Thanks for all the replies. I was leaning towards the sways first because I've read that the F-Sport springs doesn't give an even drop on an AWD. Since I live in Canada where we have bad winter's I can't afford slam it. Just looking for a mild drop that will eliminate some wheel gap on 18" wheels. Will there be a big difference in handling with just the front/rear sway bars at stock height?

I just put on the rear F Sport sway bar last week. It is a definite improvement from stock. I'll be getting the front bar in the next week or two, as I feel the car needs it.
You will notice an improvement in handling with both bars, stock springs or lowered.

no springs will give a AWD an even drop b/c the c-bracket in the front axle of the AWD models, if you want an even drop you will have to go coil overs.
also i recommend doing springs and shocks before sways for looks and handling, the is250 AWD fsport sway bars are not as stiff as the is350 sway bars so you will prolly notice better handling on the springs and shocks

I wouldn't install F-Sport springs on an AWD without the F-Sport Bilstein shocks. My roommate has just the F-Sport springs on his IS250 AWD (installed at 35k miles) and it has never ridden comfortably in my opinion. The OEM shocks aren't able to dampen the F-Sport springs under medium to full compression as the springs progressively get to their highest rates. It feels okay on smooth roads with small bumps, but as soon as the pavement gets rough, it starts getting very harsh and feels like the front suspension is at the bump stops. I'm not sure if it is actually the bump stops or the fact that the shocks aren't able to dampen the firmer spring rates at full compression - probably both I presume as my *** gets thrown off the seat as if we just drove over a 6" curb. He also has the F-Sport rear sway which does well at combating the understeer. I'd say his car handled better with just the F-Sport rear sway bar installed and stock shock/springs than with the F-Sport springs/stock shocks unless the streets are buttery smooth.
Anyhow, if you're on a budget, start with the sway bars (especially the rear one). Since you live in Canada with bad winters, I'm sure the roads get pretty rough and you'll not be happy with just F-Sport springs with no new shocks. To truly lower your car and maintain comfort/balance, you want to install coilovers or get both lowering springs AND Bilstein shocks.
Here are some pictures though of the AWD with F-Sport Springs (gap in front is larger):

I've heard bad stories about F-Sport springs on stock shocks. If I were to install the F-Sport springs I'd definitely pair them up with the F-Sport shocks. The pictures doesn't look too bad. The AWD already has a huge wheel gap to begin with. Is the uneven drop really noticeable in person?
