While running the MT 305-45-18 DR ? Im asking because one of my local sites is having a track rental coming up and I want to run at it. I was just about to order some MTs in the 295-50-16 for my 16" to replace my worn out slicks, but they are on back order till december. I dont have the money to get some 15s like I want, and I hate the sway from using slicks in the back with normal radials in the front. I'll only be running and trying out my new street tune for a 2.3 whipple, on pump gas...I know I wont see the full result till I get some real big tires under it but It'll be the first time running since before the motor blew up. As long as I go faster than a 12.0 I'll be happy...Just looking for what kind of 60's snd ETs people may have ran on them in the 18" size. Thanks guys.
