Right now or sometime in the near future? We are about 45 minutes from I40, and we will not drive the cars on the road right now because they just salted them. And well, we are not prepared for company, my garage is an embarrassment right now LOL.
I don't know if 85mm will work, I have never tried them. I did use the 90mm halos with the 99's, and they didn't affect the headlight output. I would be tempted to try the 85mm if I had some headlights to do it on... but I am all out of headlights now. The only thing I would worry about is if the 85mm will block some of the headlight output. Here is my photobucket album of a set of 99 I just did with the 90mm halos.
