I wanted to give a small update. I have been running my ETs for 3 months and 5,000 miles now. At first i was very sceptical of the spring rate but now I know better. The ability for these coils to take dips and pot holes mid corner without becoming unsettled is truely amazing. I can hold almost any line.
One small note, I am running 16x7 +42 offset wheels and I had to do some serious trimming and light rolling front and rear. I'm missing half of my front fender liners and the bolts that connect my rear bumper to the quarter panels (its now zip-tied). I am running as low as possible in the rear and am level in the front. I'm assuming because of the lower spring rate these things have a lot of travel. I would encourage ET to release some slightly stiffer springs but am satisfied either way.
