Welcome to the site!

Your run seems on par with most F owners. I personally haven't been out yet but I will be soon Most owners are right where you are, and a few are a little lower (some magazines are higher, edmunds ran 13.2). You said you had it in manual with trac off, was it in sport as well? The best I've heard anyone running in their stock IS-F was 12.3. He removed his spare a few other things as well to make it a little lighter. Do you have your slips? How quick was your 1/8th?

Wow, you had a great 1/8th time from other's I've seen! Awesome run!

Was on rear only drags but said that didn't help except for consistent launches. He was running the same times he ran with this stock wheels and tires with the exception of the consistent launches (so he said). That's the reason I didn't mention it to begin with

I would disagree on the comment about the soft compound tires not helping. My best 60 foot time was about 1.9 without loosing traction. If i had soft compound tires i could easily launch at a higher RPM without losing traction. I figure i could get a 60 foot somewhere in the 1.7 or so range which would translate to a good 3-4 tenths at the quarter mile. Two of my friends have bone stock C63's and we all went to the track the same day. The only difference was one of them had soft compound tires. His results were exactly as i outlined. He was getting consistantly better 60 foot times than my other friend which made the difference at the quarter.

Here is the link, specifically post #103 where it says he is unable to get below 1.9 with or without drags. Enjoy

Hey thanks for the link Mike. Based on what i could see this appears to be the same guy that goes by the name Cole on dragtimes.com. If you look at some of his earlier runs on that site (pre drag radials) he was doing 12.5-12-6 so i would say the tires helped him out a bit. http://www.dragtimes.com/Lexus-IS-F-Timeslip-16388.html

Ah, didn't see his earlier time slips, just looked at that page that I had bookmarked. Also, I just took his word that they didn't really help on the F. Good to know, when I get out there I'll let you know how I do

Just to clear some things up and congrats to Scotty on your excellent times (currently 3rd quickest to date at the strip that I know of). The drag tires that I use do NOT do anything for quarter mile runs except keep things consistent off the line. When the temps drop below 50, stock performance tires are just too inconsistent due to the cold and additional power coming from the cooler more dense air. The biggest factor in my times come from weather conditions more specifically Density Altitude. Check out my 2IS drag strip journal link in my sig for details and if you want I can add your times to the spreadsheet for comparison sake.

Thanks for the clarification Caymandiver
