    Multiple engine tunes for your street / track car?

    Other things I've used multiple tunes for is throttle response changes (less aggressive for wet/slick) and rev limiter changes (higher for autox where it is low gears and short duration). But with NA generally try to always run the max power tune for your fuel, unless you want to trim for NASA...

    school me on Forscan

    I've used it on my cars and trucks, but mainly for modifying small parameters in the BCM and other modules - like turning off the double honk, changing tire sizes for speedo adjustment. It can read all the modules in the car, and show the hex values for all the parameters. You can edit them...

    S550 3rd times a charm 2021 GT500

    Sorry to hear about the tough first event, but the potential looks great with the new package. Now it just needs more track miles on it.

    Why new front splitters seem to have an upturned lip? (AJ Hartman please help)

    Another benefit is under heavy braking there is less chance the splitter will choke off the air to the under body. So as not to cause a sudden reduction of DF and porpoise effect.

    2021 GT500 CFTP Sway bar Upgrades

    Those are the correct steeda springs. Its about 1/4" drop on a cftp car.

    2021 GT500 CFTP Sway bar Upgrades

    You would need to slot the strut-knuckle mount or open up the strut tower and use an aftermarket camber plate like steeda or vorshlag to get more camber. While doing the spring install is a good time to slot the stut-knuckle - just needs 1mm to add 0.5-0.75 degrees.I was never able to beat...

    2021 GT500 CFTP Sway bar Upgrades

    Hi, I've played with both bmr and steeda springs and bars. The oem bars are actually decent, just lack adjustability. Steeda's massive (38mm) front bar is the only one that is meaningfully stiffer than oem. I like it paired with their standard 25mm rear bar. The 19mm competition rear bar I...

    Trailer winch recommendations?

    I've been using horse stall mats (4'x6') cut into 10-12" strips to replace all lumber. They lay over and conform to ramps etc. to provide that extra 1/2" or 1" when needed.You can just see them in my picture, I had a couple of 4ft sections laying over my race ramps. Very handy.

    Trailer winch recommendations?

    No snatch block, straight tug in. The ramp makes it easier to pull into the trailer. No issues with using a heavier winch, it will just pull a bit faster. I drive partway up the ramps, then hook up and winch the rest of the way. Walking alongside to steer the car.

    Trailer winch recommendations?

    I actually prefer loading with the winch, as I can watch the spitter clearance on the ramps, and later fender clearance (only about 1-1.5" on each side) closely. No way to see that from in car.I've used 2000-2500lb atv winches for years. You are not deadlifting the car, its rolling in...

    Gt3 rumor is true

    Thanks for posting, these are great to watch. The challenges they have even with all the resources available.... and did you see the thickness of those brake pads!

    Rear Toe In = Grip

    I had played with more toe in (1/4 to 1/2" total) to help stability on corner entry, but it did not make much of a difference in the entry phase. I solved that with aero, so may need to revisit more toe in than the current 1/8-1/4" to get better drive on exit.
