I came from FRPP "K" springs which offer a similar drop but are very harsh. The Sportlines give me a nice stance without the harsh bounciness.

I was nervous about putting these on my '11 V6 Convertible because the factory ride was so nice and I didn't want to screw it up. Much to my relief, these springs are a wonderful compromise. Perceptually, the ride feels a little stiffer (maybe 15% - not very much) but the cornering and "nosedive" are MUCH better. On smooth surfaces it rides just as nice as factory, and gets just a little bit bumpy on rough roads - but not enough to make me mind at all. I had a shop install them, which cost 1.5X as much as the springs, but it was still worth it.

I had 2 1/4" wheel gap in the front and close to 3" in the back. With the sportline springs and pro-damper struts/shocks, I am now riding about 1/2" in the front and back. I do have a hard time with speed bumps mostly when the family is with me so I try to avoid them at all costs. I love the stance now glad my floor jack is a low profile! Note the pro-damper/spring set (4.10135.780) includes new bump stops so no need to purchase them separately.
