Interesting. The front doesnt tuck as well as I thought it would. I think the binding of the front spring in conjunction with the poly spacer does that.
Mutt, did you get under the front of the car to inspect the IFS whilst flexing ? I think you should look for 2 things.
1) front coil bind
2) how far away is the top bumpstop from touching ?
The front end of mine tucks well (for an IFS!), however its STILL no touching the bump stop - makes you wonder how the hell they engineered it for stock right ?
Here's a pic from yesterday - front tuck
