I don't think I've been very successful in talking him into coming down for it.

I expect to be there Sat-Sun 10/27-10/28 with 3Balls Racing. I'll be coming from Detroit.

It's a 2-day weekend event at the end of the Oct (27, 28).

I'm going to decide after this weekend. The only thing stopping me is that it is 720 miles and 12-13 hours from Boston which is a long way to tow a trailer. At a certain point I start to question my sanity when I spend more time in the truck than I do in the car

Once we installed our new bushings ... And reinstalled the ASTs with springs... The ride height had dropped 2.5"......they (oem bushings) create that much bind.
The OEM rubber bushings are evil in all sorts of ways on this car.
Our suspension now is like butter without load on it.
I cannot wait for next week .... It's going to be a whole new car in Sooooooo many ways.

I hope I am not misunderstanding this...Are you saying a bushing change dropped ride height 2.5 inches? If this is the case what happens to those running on Swift springs and Koni Yellows? Just curious cause I may want to do this.

from my understanding, this phenomena is normal when upgrading from rubber bushings and coilovers are usually the solution to this. if that's not an option, im not sure what else can be done.

For all intense purposes yes.
There was that much bind in the OEM bushings that it was helping support the car.

Not sure how that's possible, as all bushings are supposed to be installed/tightened at ride height, and come like that from the factory.
If they're installed with the suspension at full droop then they'll be raising the car a little, but that would put the bushings under twisiting stress at all times and wear them out prematurely.

Just telling it how it is or was on our car.
On paper no bind with rubber bushings installed at factory ride height sounds great.
But in the reality.... It's not how it is or was when we removed all the oem bushings...especially on the rear on the car.

If this is the case what happens to those running on Swift springs and Koni Yellows? Would the car then be "Slammed"? I would hate for this to happen. I assume I would need to contact Swift to have a special spring made to accomodate this?

If you are at near factory ride height I don't think there is significant bind, the issue is when you attempt to lower the car significantly then the bushings start to bind up since the angle of the arms is longer as originally designed. I don't think the swifts drop the car enough to create significant bind.

you will probably need coilovers.

But he stated that changing the bushings alone at stock ride height caused a 2.5 inch drop. Now introduce Swift springs with Koni's into that equation I'm going to have to agree with Zman8...Coilovers

Yes but the car was already lowered significantly before they started, on a street car I don't think this would happen. Plus not sure that I would put solid and delrin bushings on a street car, that would be pretty weird. For a track focused car, hell yeah - and yes add good coilovers.

If your asking me : if you replaced all the oem rubber bushings with a proper delrin and or spherical kit.... And then installed a standard "lowering" spring ...In my opinion ...would it lower the car more than the typical drop ... when only the "lowering springs were installed"....
Then my answer is YES.
How much lower..... No idea.

No idea what stock ride height is but they are allowed to be 3" or maybe 3.5" at the lowest point on the car in GS if my memory is correct. I am sure they run at the absolute limit of being "legal". I have no idea what stock ride height is but I don't think this is that significant of a lowering but maybe I am wrong.
