Racers typically try to stay between 230-260°F. And that's with a lot of aftermarket cooling mods. It is difficult to do in a street car.
Oil additives begin to degrade at 270°F so really as long as you stay under 270, you are fine. That's not to say if you hit 290°F one weekend that your engine...
For track use, ditch the factory wheels and buy some 11" aftermarket wheels so you can run 305's.
If that's not an option for you, then I wouldn't go any larger than 255 on a 9" wheel.
These cars desperately need more tire in the front than what they come with so I would highly recommend...
When you say PP rims, are you referring to the 19x9 and 19x9.5 wheels? You will not be able to fit 305s on those, just FYI.
I know you didn't ask me but I also run 305s on every corner. In the front, I have a net offset of +25 (+50 wheel with 25mm spacer) at -3° camber and I do get slight...
Fair enough. I guess I was mentally comparing it to my standard GT at 3800 lbs.
Though I think I've read S650 premium GT's are also 3900 lbs which would be an increase.
Either way, still annoyingly heavy.
I know Ford does their homework and has probably determined that the typical flagship Mustang buyer still wants the "supercharged muscle car" but man this platform needs to enter the 21st century and make the switch to turbos. Smaller, lighter, more efficient, more tunability, etc.
I'm sure...
I suppose that would be fine, but to me, the transaxle and the SLA front geometry are what would make this a "GTD-lite" vs just the next GT350/GT500. Well the pushrod rear geometry definitely as well but no way I see Ford carrying that over to a standard production model car.
Keep the 5.2L but ditch the supercharger.
Ditch the expensive Multimatic shocks and replace with regular Magneride.
Keep the body parts but replace carbon with aluminum/fiberglass.
Keep the transaxle.
Now this would be a car I would be very excited about. Probably right around the $100k mark.
Hey mods....why am I still getting email notifications on this when I already unchecked that box?
(why anyone would need an email every time someone comments is beyond me)
I would love it if Ford made a new Mustang about the size and weight of the older Fox Bodies. Could have a smaller, higher revving V8. Would be an incredible driver's car.
I mean it won't explode but this guy is going to be pointing by Miatas in the turns and wrestling limp mode on the straights. It's about as ready for the track as a Camry is.
I'll get off my high horse now. Have a nice day.
"Customer wanted a track build..."
Nitto G2 tires 🤦♂️
275mm tires in the front 🤦♂️
Whipple 🤦♂️
Whipple is going to make it overheat in one lap but I suppose that's fine cause with that much power and those sh*tty tires, this thing would fly off track at the first turn.
Track build it is...
Not sure if this has already been posted here but @Epiphany found the GTD curb weight over on M6G.
At 4,300 pounds, I'm no longer interested....not that I could afford one anyway. My vote just just shifted to the ZR1.
Apologies in advance for being *that guy* but I couldn't help myself...
You certainly don't need a wing to go 140 mph. I've done 145 mph in a plain-Jane GT with no aero whatsoever.
Stunning car, though. I bet it's a riot on track.
Another vote for Roush axle-backs. You get 80% of the sound for 40% of the cost (compared to a full catback). Reasonably quiet when cruising but gets loud when you get on the gas.
If you want super cheap and super loud, yeah just cut everything off and weld in some straight pipes.
If you want...
I'm surprised the 86/BRZ & Miata don't sell better. I figured high school/college kids would be all over those. Perhaps that demographic just can't afford any brand new car these days, let alone a sports car with limited practicality.
Also surprised by the Supra numbers especially with the...
