So we finally were able to do a track rental with all our buddies before the end of the season…
We hit up Atco today to finally attempt to hot lap the S4 for the first time…
The car: 2013 B8.5 S4 DSG
Mods: GIAC Stage 2, GIAC DSG Flash, AWE Pulley, APR CPS w/o Pump, AWE Catback, Roc Euro Intake, JHM LW Rotors, 46LB 18" winter wheels with 245/40/18 Continental DWS
Driver: The STIG aka Tsivas the Jockey lol (182lbs as of this morning)
Since we pretty much had the track to ourselves and could do whatever we wanted we experimented a ton with a few different things. We did about 15 passes in total, not sure the exact setup on all the passes but i do know the two fastest most important setups. IIRC slowest pass of day was an 11.70 lol. Not too shabby.
Started with an 11.546@119.08 with a 1.676 60’ then got the record 11.462@120.03 with a 1.669 60’ followed by an 11.469@120.17 with a 1.681 60’.
This setup was as stated above, without a spare tire and jack and without the front passenger seat installed. The runs on MS109 (105 Octane) on GIAC 104 File.
We did a few more runs with this setup, also tinkered with tire pressure through the day. All these runs were done in left lane also. Seemed like both lanes were running similar, but right lane had better prep, didn’t seem like we had a problem with traction so as long as we were able to chose a lane we stuck with the left.
Later on in the day after eating about 9 slices of pizza lol, we decided to throw the front seat back in, left the spare and jack out still and do a few more passes.
First run out after the car sat for over an hour was a 11.494@120.24 with a 1.718 60’. I was shocked that the seat only made that much of a difference, especially since it has to weigh like 65-70lbs. The two following passes after that were 11.556@118.85 with a 1.675 60’ (dropped the tire pressure with hopes of better results, however all we saw was a better 60’ ET and trap both dropped), third run was identical specs to second run with an 11.563@119.52 with a 1.713. The last two passes were in right lane… I’m thinking that had a little to do with the slight drop in trap but could just be the car also.
So anyways i think that just about sums it up. So the seat being removed didn’t make a difference at all really. I got my goal and slipped into the 11.4x in both trims and the car overall just ran like a champ. Not one hiccup all day. Really makes me miss my B8, but hey wasn’t a bad day for the S3 either, snatched the record for that car too 
11.923@115.06. That car only has a tune, downpipe, FMIC, and VWR intake. Nothing else. Not bad for about 2k in mods.
Pics of slips coming in few minutes along with a few videos. DA ranged from -500 to -200 throughout the DA. Temp stayed in the mid to upper 50s.
