Suspension thread for 2IS
I know I am new here, but I spent a whole lot of time looking for suspension threads. Could a mod sticky a thread that encompasses all of the suspension manufacturers that support the IS250/250? Specs on dropF/R, and softness/harshness would also be nice to the guys looking in to upgrading from factory springs/suspension.
With a sticky, there wouldn't be a whole lot of searching and countless threads of repeated inquiries for the IS suspension.
For those with coilovers:
cornerweighting tips 1
Cornerweighting vs. Cross weighting
Cornerweighting tips 2
Edit: If you have these lowering springs, please comment on how much they drop, and the difference in stiffness over stock. if you can provide a sideshot, that would be even better as it would illustrate the differences between factory and modified stances.

If someone creates a good post like you've defined we'll add it to the 2IS FAQ. Unless I missed it one doesn't exist... why don't you create it with the results of your searching?
With that post in the FAQ, there wouldn't be a whole lot of searching and countless threads of repeated inquiries for the IS suspension .

While it's fantastic to have pics showing ride height of each set of lowering springs, IMO it's pointless to post a picture of each coilover setup's ride height since it's completely up to the owner to decide at which height he/she prefers to run the car. More important to me (for comparison purposes) would just be features/specs and owner feedback.
I'll throw in a picture of my car on the H&R Sport springs:

I had the tanabe springs on my 2004 accord, the height was fine in the rear, but the fronts were not low enough in my opinion. I like to see the entire wheel (not tucked what so ever in wheel well) and they ddi this for me, but there was still a finger and a half of gap in the front. It bothered me, but the ride quality/comfort was perfect (not much different than stock).
I will probably get the tanabe setup again for my IS350 but wanted to give you all my 2 cents on their springs if it helps anyone. I go for a drop mainly for cosmetic purposes, if it helps with anti-roll, cool too.
