I recently upgraded all my bushings to poly and installed uprated 200lb springs. My ride height is now 13 3/4 inches (wheel arch to center of hub) in back and 15 1/8 in the front. Now obviously I got a bad set of springs and the supplier I got them from is working to remedy the situation. I was wondering what measurements everyone else who has done this upgrade has ended up with. I know what the original specs are, just wondering what real world results everyone has gotten.

have you driven it yet?as you have fitted new bushes too they along with the springs may well settle a bit.

Yes I drove it and it handled great. The nose just sticks up in the air. The one thing I pointed out to the supplier was that the poly spring dampers are a bit thicker than the oem ones so he's taking that into consideration. Not only is the front up in the air but technically the back should be lower than it is, since these springs are supposed to drop the car 1" from stock height. As far as the springs settling, they are "guaranteed not to settle or sag", so go figure. I'm sure the spring dampers will settle a bit but since I installed them front and back that shouldn't be an issue.
Original specs for my car are 13.59" front and 13.92" rear, top of wheel arch to hub centre.

Haven't measured mine but looks like this with "200 lbs/ft, 1" lowered" springs



At least it did look like this before I took the car apart  

This one (on much stronger front springs) has a ride height of 340/325mm (front/rear) ...

I have the same problem, though with an ebay bargin set of 200lbs, 1" lowered springs. Mine are 14" at the front and 13" at the rear. My S&S sports exhaust tail pipe and box have been reprofiled several times!

Finally got a new set of springs from S&S and they are about 2 inches shorter than the ones that I had previously installed (had an extra set to compare to since my supplier sent me a second bad set to intall). Can't wait to change the rears and take out the fronts tomorrow. If all goes as planned I should have the fronts back in on Tuesday. Looking foward to finally having the car sitting closer to the ground.
