Hey Jen!

My kid didn't mind my Eibach sportlines...it was the Greddy Sp I had to get rid of. Baby's ears are really sensitive and are still developing so I would be more worried about your Thermal exhaust than the springs. Swap the exhaust from the Talon to your Spyder and vice versa. GST muffler is way more quiet...a lil less flow but it'll feel alright. Do the same for the springs if you want a more cushy ride. I don't think any lowering springs will give you a bouncy stock ride.

My Talon has been good baby transportation even though we use the SUV more. Remember that we have tethers anchors in the trunk. Good luck. :)


EDIT: If you go with Eibachs- the sportlines are way more bouncy than pro kits. The pro kits I had on my 1G were stiffer.
