Lowering Springs IS350 2014 Fsport AWD recomendation
#16
Reverse rake means the rear of the car sits lower than the front, just the opposite of forward take when the rear is higher than the front. Personally I don’t mind the reverse rake. Lexus built these cars with some reverse rake to them

RWD models will sit relatively level, it's the AWDs (F-Sport 3.5L in particular) that get the reverse-rake or rear-squat look, with RS-Rs in particular. For whatever reason, larger rims seem to mitigate that somewhat. Forward rake will only come from either putting springs only in the front or using a bigger-drop spring in the front.

Thanks!! I've never modified any of my past cars, do you know roughly how much it will cost for installation? Also, just by changing the springs, that doesn't affect anything on the drive modes right? specifically the "Sport S+" mode where the suspension is supposed to stiffen up a bit? or the dampers? something like that...

As for installation, best would be to know somebody because a lot of shops will charge "by the book", which is something like 7+ hours. I had one guy quote me over $1100Can plus taxes, which even he admitted was ridiculous. From what others have said, the whole job should be 3-4 hours, even less if someone's done it before.

If you have AVS it only affects the shocks; the springs are non-controllable and just affect the ride height and stiffness/travel of the suspension.

My car does have the AVS, in regards to that, does it impact it negatively? or can you provide a little more information on how big/significant of a change? (sorry for all the questions).Just trying to understand before I make any changes since i've never done it before.
#25
I'm far from an expert, but because the springs not only stiffen the ride but also shorten the travel of the shocks, I would imagine it reduces the noticeableness of AVS to some degree over the stock springs. The car should have a firmer more AVS-like feel at all times.

Im assuming the springs fit the same. The main difference from my understanding is the ride height. Instead of 1” in the front it’s now 1.4”?
