    Hi All,

    I've followed these forums for quite a while and learned so much I wanted to give back some of my own experiences to help out others. My car is a 2017 GT Premium with a A6 and 3.55's.

    My first trip to PBIR I had made these mods:
    Lund FF tune, Ported 18 Manifold, Texas Speed no cat LT's, PMAS tune required cold air, Race Star 17X10.5 with MT SS 305-45-17, BCRacing coil overs, 3 inch electric cutouts, Steeda IRS bushing support, Steeda IRS alignment kit, Steeda subframe braces. Here is the best run:
    DA: 2100 feet
    [email protected] 1.986 60 foot
    A little disappointed but the car was getting grip initially and then spinning. More work to do.
    For my second trip to PBIR I added these changes: Viking Crusaders set at C2/R6, RaceStar skinnies, Removed back seat, sub and tire kit and raised the front end 1 inch. Here are the results:
    DA: 800 feet
    [email protected] 1.894 60 foot
    The spinning was gone but 60 foot was still not what I expected. So I added a CircleD 4C, Baer Eradispeed rotors front and back and removed the passenger seat. Here are the results:
    DA: 1100 feet
    [email protected] 1.629 60 foot
    All of the runs were on E85 , cutouts open, and foot braking to 1500 RPM.
    I have a Meziere EWP and shaftmaster DS coming this week hoping to get back out to the track next week I will update my progress with those changes. Also installing a 2 step and transbrake. I'm hoping with figuring out the optimal launch RPM tuning the rear shocks and some good DA I inch a little closer to 10's.

    You have a lot of mods. You can probably get down to 11.2-11.3 by improving your sixty. But at that DA. It’s going to be tuff. Keep removing weight. Might have to get creative. Get a new k member. That kinda thing.

    Nice car! I thought of trying to go 10's NA but I think FI would be the cheaper way. Of course once you hit mid 10's FI you would want to turn up the boost for a single digit slip. Good luck!

    Swapping out those brakes are going to be some killer weight savings. I'm trying to go really fast all motor as well, so I am always looking for ways to cut a tenth so off of my ET. Let us know about that EWP. I have been debating about picking one of those up for a while now.

    You should be able to launch alot higher than 1500 with a 4c converter!

    Load the converter and let it eat.

    Looks like you have a solid wheel tire suspension setup.
