    What lightweight suspension components? Bigger wheels = more weight. Bigger tires = more weight. Bigger brakes = a lot more weight. Making almost 300hp more means it's going to make a lot more heat, so it will likely need a bigger radiator, engine (oil cooler), trans and diff coolers than the GT350 if it's not going to overheat in a lap. A larger radiator, engine oil cooler, and especially brakes are more factors that can easily push it over 4,000lbs. I don't think your diff and trans coolers are correct estimates with fluids, pumps, and sized large enough to prevent the car from overheating.

    There's too many differences between a base GT and a GT500. Having the weight of a whipple'd GT350 would be far more telling since the weight increase would be less and the body closer to the same due to the GT350 already having cooler and big brakes.

    Could be the carbon fiber reinforced plastic K-member Ford was working on, more use of aluminum in the suspension (like the GT350's knuckles). They already have the CFRP radiator support from the GT350 also.

    We will definitely see on all the cooling, but 20x11 or 20x11.5 forged wheels will absolutely be lighter than the cast 19x9.5 PP wheels, and 315/30R19 Cup 2s are lighter (28 lbs) than the 275/40R19 street tires on those wheels. Even the PP2 wheels at 19x10.5/19x11 are lighter than the narrower GT PP wheels. The rotors will not be that much heavier at 16" vs 15.5", particularly being the same 2 pc style as the GT350. I ran that mass calculation a couple months ago and it was something around 2-3 lbs per rotor (GT350's are 30 lb, with a portion of it being the aluminum hat). Even with a larger caliper and pad you're talking 10 lbs there.

    Very nice. I prefer the style of the fastbacks tho. Just saw one today during a bike ride, looked and sounded great.

    Auto or Manual?

    I still don't believe the whole 4200+lbs unless they pulled some crazy active aero or suspension like the Ford GT. I'll be EXTREMELY disappointed if they somehow managed to add 500lbs or so onto the weight of the GT350 and didn't do anything to mitigate the weight gains, especially with how long the car is taking

    Forgive me if we've already been over this, but has it been confirmed if they are going to keep magneride on the new GT500?

    I don't know what the current WOTS is, but I can't imagine the high[est] end Mustang not having it, it's standard on GT350 and the revised MY19 GT350s were said to have suspension/aero engineered for the GT500 - plus the ZL1/Z06/ZR1/Hellcats all have some variant (the one exception I guess is the ZLE).

    I suspect they're going to kitchen sink it and make almost all options standard - I'm curious if they'll use the digital dash, since it's a pretty direct fit - this car is really interesting with some exterior design elements coming from the Gen 1 SS50 like the GT350, but having access to the newer tech of the MY18+ Gen 2 cars (like the dash).

    I'm sure Magride will be standard, but for the rumored "R" model, I'd be very excited if they switched to DSSV. But if they don't offer the digital dash, that's a MASSIVE L. That's a pretty big selling point for the 2018s, and it's super easy to add as a feature. If they don't have it in their top tier mustang, that's just ridiculous... I have NO idea why they didn't put that and the 2018+ taillights on the 2019 GT350

    Bad Feng Shui ... :D

    Seriously though, I guess they didn't like the design language conflict, since the Gen 2 front light tribars match the rear lights, and pick up on several other details that use the same angle. Like I sort of implied, it is a bit of an interesting design choice to have prior to facelift design elements continue post-facelift in the "prestige" models (but I get the manufacturing/re-engineering costs, etc.).

    When the 6G Camaro got its gen 2 facelift, the ZL1 front end did _not_ change, even though it adapted the new rear lights - kind of the some of the same engineering rationale I suspect (i.e., the ZL1 has a unique front end, specifically designed around the coolers/intakes).

    See, I would understand that if it didn't appear that they're putting 2018 taillights on the GT500. That's what has me confused

    Agreed. I think it's more for aerodynamic benefits than tooling and such... they already put so much time. effort, and cost into optimizing the GT350 front end, they don't want to do the same thing with the 2018 front end, even if it COULD end up being better. Just typical American performance shortcutting
