I have the rota C8s on my civic. They are really nice wheels for the money, and they are pretty light too. The only thing I dont like about them is the fact that they only came in +38 offset, and rub a little sometimes. Slipstreams come in +40 which may help a little. I would definately buy another set..
Check
www.groupbuycenter.com they have good deals on them out there often.
Ive had a couple sets of 17s in the past. 15s are much better if you dont mind giving up some looks for performance.
