New owner here. Just bought a 2006 is250 that was lowered by previous owner. Looks ok, but I'm wondering how much drop is in the vehicle. I've searched the boards and most of the posts indicate the drop but I can't find the stock height to determine my drop.

Car is sitting on 225 17's and measures ground to fenderwell 24 3/8" on the back and 25" on the front. Any help on what the stock ride height is for these tires or what drop I currently running from stock?

Thanks,

I'm assuming you have AWD because of the 17's? If so, the following are the measurement for stock height from the ground to fender.

Passenger front - 27"
Passenger rear - 27.25"
Driver front - 26.75"
Driver rear - 27"

I just measured quickly so maybe someone else can chime in. Also, be careful when lowering AWD because you can damage your CV boot. I think the safest height is 25".

Anyone know the stock height for a stock RWD on 18s?

From floor to highest point of fender : ~27" all around...and this was with the Sports Pkg spring/shock combo.

Here is my thread on my install of the F Sport springs in my '06 IS350. I included before and after measurements. I'm on 18s, btw. Hope this helps.....

It should be essentially identical to the 17's because you need to maintain the same overall circumference (wheel + tire).
