RSR down only in front on AWD
Sorry if this a repost but I was wondering if using JUST front springs on an AWD car would have negative impact on the drivetrain? I’m looking to get rid of the reverse rake (and add a TINY bit of rake - I prefer that look) and I remember seeing one person doing it but can’t find that post again so I’m unsure if he was RWD or AWD.
thanks!
thanks!

Welcome to the forum.
I can't remember which member did this, but I recall the thread you're thinking of.
In his case he put Downs in the front and Half Downs in the rear...if we're talking about the same member/thread.
His goal was to level out the vehicle, which it seems he achieved.
I suppose if you just put the Downs in the front you would get a very slight rake...but I don't think anyone has done that on the IS, so unsure how the vehicle will react.
Personally I don't think it should cause an issue...but that's just my opinion.

I suppose if nobody has hands on experience with it I’ll be the first to test it. Worst case scenario is I can find a way to make my aggressive rear wheel / tire combo (19x9.5 35 offset) work without rubbing - I’d guess for the MOST part I would be good but when loaded with people in the back I feel like I’d definitely rub a good bit... seeing as I get a TINY bit of rubbing right now while weighed down.

Regardless of height difference, isn't there going to be some negative (or weird at least) affect on handling with stiffer springs on front and stock in the back?
Trying to imagine this. I suppose maybe not but makes sense that it would cause some weirdness with the different spring tensions front to back.
Weirdness = technical term

If, for instance, the stock spring and lowering spring both have the same weight rating, then it should be fine as a daily driver...even if the ratings were close, it should still be fine.
The other consideration is what you're doing with the vehicle, and in this case most are using it as a daily driver...so really you'll probably not notice the difference.
If someone was tracking the vehicle or driving more spirited on aggressive roads consistently, then yes, they will likely notice a difference...I guess that weirdness would depend on the gap in performance between the stock springs and aftermarket springs.

In a technical aspect you would be correct if we knew what the rating was for the stock springs.
If, for instance, the stock spring and lowering spring both have the same weight rating, then it should be fine as a daily driver...even if the ratings were close, it should still be fine.

Thanks for all the responses everybody - Gonna try this out in a couple weeks (waiting on my axle-back to get both done with one visit to the shop). I'll be sure to post pictures and share about how it feels!

In case anyone is as curious about this as I am - These pictures were taken yesterday (day OF install) - zero issue handling driving home (drove a LITTLE hard just to make sure). Everything felt great. I expect the front to drop another .25-.5 inches over the next few weeks as they settle. This is EXACTLY what I was going for and right now I'm very happy. Will update with settled pictures in a few weeks!

As others have said, going half and half on springs will have an effect on handling. Even if you are not track driving, what if you need to do an emergency maneuver in traffic? First, the spring and damping rate need to be consistent with stock. Just changing to shorter springs will NOT improve your handling. Shorter springs can bottom out on the outside wheel during harder cornering, causing a side of the car to go 'light' and resulting in a spin. This isn't my information, its directly from the head of product development of a major suspension company.
