I received and installed my Progress Sport Springs. I have some feedback for both installation and results.
As far as installation goes, you
do not need to cut the bump-stops with these springs. Additionally, the springs come up-side down in the box with the stickers indicating which spring goes where on the bottom. The most important thing when installing these is make sure the "coil pattern" or spirals match your OEM springs when you take them off. This will reduce the chances of "popping sounds". Also, the Progress springs are wound very tight at the bottom, and it's difficult to get the little rubber cushions from the stock springs on them. This can be solved by heating the rubber up in hot water and squeezing it through the gap in the springs with some mild soap.
The rear springs were pretty easy, however you have to really push down on the caliper hard to get the new springs to slid into place without rubbing the rubber cushion off the bottom.
Install took me about 6 - 7 hours because I completely took off my windshield crowl, strut tower trim, and windshield wipers. This allows you complete access to the top of the strut tower. The reason for this; loosen the nut that holds the bump stop into the shock BEFORE you take the strut tower off. If you don't do this, your going to need a vice mounted on a work bench to hold it. I did not use impact tools.
DRIVING IMPRESSION:
My first impression was the ride is fantastic. The suspension actually feels softer than stock in regards to bumps/rough surfaces, and tighter in corners. I've felt FA5's with Tein S-tech and IMO the ride quality is no comparison to the Progress springs. I think this has something to do with how many spirals these Progress springs have.
DROP:
My springs aren't settled yet and there is already 1.4" of drop up front, and 1.5" of drop in the rear. The right rear was 3/32" higher, but I think once they settle they'll be about even. I'm estimating another .3 - .4" of drop once the springs settle, and I'll post pictures tonight!
CONCLUSION:
Since these springs are dark gray in color, they look almost OEM once they're on the car. Since you have to take the strut towers completely out of the vehicle, you have to get an alinement done. You can say "I don't need one" all you want. You do. My car is at the dealership getting it done today, and it runs $65.00. Most places will also torque the struts and other assembly bolts to spec while they do it (just to make sure you did a good/safe job!).
I highly recommend these springs. Excellent product. No popping sounds, exquisite drop, but the best part is; the ride quality is super smooth.
Thanks CorSport!!!!!
