    Decibel Rule

    On the other board I saw the turn down/turn away suggestions. You could also use a plug/baffle on the inner pipes (where the valves are) - they are the straight through - lightly muffled pipe that makes the most noise. Some of the newer tuning software like pcmtec can edit the active exhaust...

    ‘Bouncy’ rear end after rear lower control arm monoball bearing install on a GT350R

    I did not get any extra bounce when I made the same changes to my gt500 mag ride. (cortex arm bearings and fp toe link bearing). But I do have a DSC sport controller that has some added rebound dialed into the rear. Before the shocks and springs went in the rear suspension was very free moving.

    Tornado hits Willy Da P's house , but there is even worse news............

    Glad you are ok, and only the trailer got sacrificed. Terrible to hear of the other losses all through the midwest. OK got hit hard too.

    I want to get started in Time Trials in my GT350. Thoughts on my particular setup and SCCA vs NASA?

    The nankangs are underrated for a 200tw. They are very good and come in big car sizes. Only thing that outruns them are yokohama AO52. Good wear, fast to the cord, and can hook up a gt500 in 2nd gear.For SCCA which is 200tw focused it is a solid choice. For NASA hoosier buys you more...

    S550 Is this correct? (Front Sway bar)

    The links can work in either position on the strut, but they really should match to have even loading left to right when the body leans. Especially with adjustbsle fron bars I move the upper position to the one closest to straight up/down.

    Better buy, Mach 1 or GT500?

    Now that would be a hoot to drive!!

    Better buy, Mach 1 or GT500?

    Yes, and the wing makes a real difference at the speeds the car can hit. Many of my early frustrations with the handling were solved with my anderson replica wing.

    Better buy, Mach 1 or GT500?

    It took me a couple of iterations to get my GT500 to get past my previous GT350 lap times. From the factory the non cftp GT500s are very soft, and quite loose which really saps confidence. Once I got good tires on, I worked through alignment, springs, and swaybars to get the balance where I...

    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.
