    300A Connection point turned up so some quick fab the other night and bracket made, nutserts in and a quick paint. Mounting point done. Spare hours while dinner was in the oven, grabbed an extra pair of hands and crimped all the cables and bolted...

    The old standard that a 100 lbs of weight reduction is worth a second of time on the track is seldom remembered. I applaud your mods, weight off is such a simple way to gain time and speed.

    The hardest of the two, prolly the 3, it's been awhile.

    Got bored waiting for people to get around to doing my machining for the front struts. Seriously hard to find someone to do some manual machining that isn't either inundated with work or who actually gets back to you about doing it even though...

    I had this issue with my 2017 GT350 and the hose that comes of the reservoir going to the clutch had been known to not seal properly. I saw a fix for it online and it was put a small hose clamp on the hose on the barb or a zip tie. I put a zip...
  • I knew that the sensors existed, but I didn't know if anyone outside of top tear race series used them. Apparently I missed the joke/sarcasm. Lol (see full post)

  • Hey Adam, I’ve been following the Silver Mustang build on the channel, and I’ve got to say, the sound of that car during the first track tests was absolutely spot on. It’s got that perfect, gritty '68 Bullitt vibe that every Mustang fan dreams... (see full post)

    Why wouldn't Ford do it, especially on "track pack" cars? Is it a curb rash fear on a "stock car", probably driven on the street at least some?I don't think they did this type setup on even the GTD. (see full post)

    Looks like he spun the tire under load, across the elephant turds that line the track edge.

    No idea what happened (but that one tire looks to be dated 2023?) but you shouldn't have to worry about an R7 batch problem since the R8 is a thing now...er....trackattackpro or whatever they call it.

    Skip ditching tires only to buy take-offs, just keep your eyes open for discounts and get a new set. Discounts are available often through TireRack and also places like Costco. You can even get RE71RZs through Costco , though you have to order... (see full post)

    Inspect heavily, does the rubber appear like they sat outside in the sun for 7 years. Any cracks, even minor starting?If you had bought them new and they were in a climate controlled (more or less) basement for most of that time, then I'd say...

    We have a perfect example of this concept with our own Dave Whitworth. He mounted some dinky 295/18s on his 12 inch wheels and was blowing folks away in CAMC. This was on a set of RE71RSs so this may be a better example for some over the PS4Ss in... (see full post)

    Bill Pemberton reacted to Dave_W's post in the thread Wheel Width v. Tire Width with Like Like.
    I remember reading a funny story (not sure how accurate it was) that between the mid-1960s and 1970s, F1 teams found that using a slightly wider wheel than the tire manufacturer recommended was faster, as it supported the sidewall better. The...

    BP2Vet reacted to Dave_W's post in the thread Another tire question (bear with me) with Like Like.
    Like others have said, check for signs of age cracks. Run them a few miles on local streets (not highway speeds) and check again for cracks, blisters, or signs of tread/belt delamination. Drive about 15 minutes on the highway and do another round...

    I would have pointed out the obvious boost check valve between brakes booster and Intake Manifold (the little plastic thing) this have a tendency to fall but you said your brakes were fine. Usually when the pedal start dropping to the floor or is... (see full post)

    If you think it is a hydraulic issue pull a vacuum at the reservoir to make sure you don’t have a leak somewhere in the system.
