Thinking about getting slicks for my altima. The stock 18's are great but for the track I want to have a front pair for slicks. I have 16x7 and 16x6.5 rims sitting in my basement that I could use, I would only be using the front set. Now my question is what size slicks should I look for, and what else do I need to worry about when putting slicks on?

I've never been to the track before but I plan to go on the stock rubber before I go with slicks at some point. I know the gearing is going to change and the already short 1st will become even shorter etc. I already would have to shift into 4th so thats not going to change much.

My goal now is to get into the 13.9x's with just an intake and the slicks.

Thanks in advance for any and all help and suggestions.
