2019 GT350 Upgrades: Tech, Aerodynamics and Other GT500 Track Improvements

So do you have to swap out springs and shocks and sway bars a few times a year because they are worn out?

I've already replaced my tires a couple times on my GT350 because they were worn out. I put on factory spec tires, but I thought about it and made that decision. It would have been super easy to buy something else - I had to replace the tires anyway.

I agree with you that the comparison between the GT350 and GT PP2 should be completely stock vs. stock. I don't think we know which is faster on a given track. It will probably depend on the track as others have posted. I personally don't care which is faster when the difference is going to be very small - and in the real world people change out tires like they do shoes and socks.

Bottom line is: I really like my car, and I bet I would really like the new GT PP2 as well. The Coyote and Voodoo are very similar engines. To me, the Voodoo feels like a hot rodded Coyote. Both are very fun. I think the GT350 is more special, but the half life of performance automobiles is very short. That's how they get people to buy new cars.

Sorry, you caught me on a bad day. ;)

I do think that the special GT350 transmission and engine are being under-rated by some Camaro and Mustang GT guys. The gear ratios in the GT350's Tremec box are very different from an MT82. Unless the GT PP2 has a unique MT82 transmission, on track the GT350 will not need to be shifted as often. It sounds like a minor thing, but the wide power band and gearing of the GT350 do a lot for that car on many tracks.

I just looked up the '15 - 17 ratios and they're surprisingly not that much different. The 350 has just slightly taller ratios in every gear except for 5th. Which I think makes sense because of the RPM capability.


Here's the '15 - 17 ratios:

3.66
2.43
1.67
1.32
1.00
0.65


I believe these are the 2018 MT82 ratios:

3.24
2.10
1.42
1.0
0.81
0.62


The GT350's are:

3.25
2.23
1.61
1.24
1.00
0.63


Everyone talks, or SHOULD be talking about usable power and application. If you're going under the GT350's power band on track, you're doing it very wrong. Or on a cool down lap. I don't know where this idea that the Voodoo has no torque comes from. It's about WHERE that torque is. The meat at 4500 RPM is BRUTAL and it's still twisting out about 325 RWTQ where the Coyote redlines. And where as an '18 Coyote pulls to that 7500 RPM, the RWTQ falls under 300 lb ft. That is so lazy in comparison to the Voodoo.

Now go to the other end of the spectrum. The fact that The Voodoo LOSES torque from 2700 - 3200 RPM is just facepalm worthy. But again, I've never fallen under about 4000 RPM on track. If the Voodoo's torque kept on climbing from 2700 - 3200 RPM rather than falling off, we would probably see a sub 12 second GT350R. But the fact is, it doesn't. Wanna hit the 1320? Get an '18 Coyote 10R80 car all day. Plus you can't fit slicks and skinnies on a GT350...

^ Concur. It actually is not as much fun tooling around town as I thought it would be. The car belongs on the track in the high revs and at speed.

Agreed. I'm a bit disappointed the 18MY gear ratios are where they are as well, doesn't feel as peppy as the 15-17MY actually.

I bet it feels really good from 4000 - 6500 though

I meant the GT, not the GT350.


It probably does feel similar to the GT350, but with a smoother low end.

To be clear on my post, I am not knocking the performance window. It is just something that potential buyers (and in the context of this PP2 VS GT350 debate) need to be aware of. If you NEVER plan on tracking it, maybe a PP2 makes more sense. In which case, I'm not sure why you would want a street car with sport cup 2s but thats a diffrent discussion I suppose. As the saying goes, " a steed for every need". It's pretty awesome in 2019 how many options there are for the mustang customer.

EDIT: Plus, no said the Coyote is a shit motor. It's not. I just scratch my head when people say the Voodoo is "meh." I'm SOOOO sorry it's not a $250K GT3 RS...

PP1 is probably where it's at for a street brawler. Still get mag ride and those S4 tires are pretty nice.

I still don't see there being a massive gap between the 2 cars. There's really no place other than brakes that the GT350 has a significant advantage, and even at that, its no difference that a set of AP brakes for the PP with the $15,000 you save against a GT350 wont fix.

At this point, you're buying a GT350 for the name. To say that the GT350 has an extra $15,000 worth of performance is ridiculous
