I, like many people was pretty excited to see this car added to the game. As a Corvette owner IRL (c7) and Corvette enthusiast I was super excited to see this show up. I was also VERY excited as someone who spends practically more time tuning then playing to see the EXTENSIVE amount of options for upgrade parts that were available for the car. Too often lately we have been getting new cars to end up finding only lackluster upgrading potential.
So it was to my extreme dismay to find that the car is very very broken in its current state. This is NOT something that is a tuning issue or a parts issue. Not something a player can fix. I unfortunately only realised it after spending over an hour+ playing around with upgrades and tweaking a tune setup before hitting the road for final tuning/adjusting.
The car PLOWS.
Ever had the misfortune of driving the Volvo Iron Knight? Well it isn’t quite THAT bad, but it is the same sort of issue, that no tuning can fix. For some reason it just does not turn properly. You don’t even need to tune or do anything with it really to find out. Chuck AWD on it, and try and drive it around, you’ll see what I mean quickly. The turning radius is terrible. It is hard to describe but the car will like angle but the car doesn’t turn at all. It’s like the wheels don’t go. There is clearly something VERY wrong with this car in its current form.
I explained this to several friends and told them to try the car, and they knew what I meant the second they got in it.
This is a highly anticipated car, and deserves better treatment.
PLEASE DO NOT IGNORE THIS. PLEASE FIX THIS CAR. SOMETHING IS WRONG.
Haven`t tuned this one yet but found the stock untouched C8 to be wery drivable even if I missed the ZL1 power. First thing I did though was to reset the gear-ratios.
Did a wery quick test right now, just turboed and maxed out the stock engine and gave the race-suspension a wery basic setup. Soft and a lifted it up little bit to be able to feel the bodymovement.
Since RWD is messed up in this game the way around it is to convert to AWD and then set it to 100% RWD. Here is my test-setup, worked fine on my test-ride.
Wow, sounds about right. I was always thinking why RWD has so bad start because your weight is in the rear and you have full weight on rear tires. And also why AWD is so stable OK, that could be something. It’s a next research topic.
The harder the tyres are pressed into the tarmac, the more grip you get. That’s why they make cars RWD, to get more grip from the driven tyres because the weight transfers to the rear when you accelerate. And it’s also why they put engines near the back, to get more weight onto the rear tyres and increase grip. GTS models this to some extent (not sure how accurate it is, but the effect is there) in that cars with the weight more to the rear, like the 911, have much better traction in the wet.
Same way as the Rwd. Initial launch speeds are awful. Front tires loses traction unrealisticly easy and leads to understeer(With Rwd it leads oversteer).
Thats why in Fh4 only very few Rwd and Fwd cars are usuable in a ranked environment which they ususally abuse unusually underrated gearboxes to stay in the given PI range. %99 of the cars in game is just better if you Awd swap them.
I can suggest everyone to do some testing on Forza Motorsport 7. Just choose a car that both game has it and drive it sometime. The difference is pretty obvious and I was Shocked when I saw how big the difference is.
Also PI system isnt helping neither. As soon as you get a decent launch speed with Rwd or Fwd, Awd swaps starts to decrease PI. Porsche 911 Gt3 RS, Bugatti EB 110, Ferrari 599 XX E, Hotwheels Bone Shaker, Chevrolet Nova FE, Ariel Atom V8, Bac Mono, Alpine A110 Ferrari F50 GT and Koenigsegg CCGT are some examples that lose PI rating when you Awd swap them.
Is this “does not turn at all” only a visual issue? Because after tuning it my C8 does turn quite well for a S900 car.
The stock suspension setup is atrocious like on most other mid or rear engine RWD cars (McLaren, Ferrari, Porsche). Way too oversteery, so the back snaps out very easily when under full steering input.
This is just a fault by PG which they often do on above mentionend cars.
Did you research it somehow? It’s just how steering works in Forza but I am still not sure how it exactly works. From my last testing it looks like Forza guards your outer tires for maximum grip but with rear heavy cars you start to lose your front outer grip first and the the car starts to slide.
I’m also not sure and never looked into the telemetry. After upgrading to Race suspension (which is normally just a stiffer version with the same front/rear distribution) the values are set way too oversteery.
I don’t think PG determines the suspension values by hand. Since it’s nearly always an issue on rear-heavy RWD cars I assume it’s a fault within their automated process. If it would be a problem with the car itself tuning wouldn’t be able to fix it. But it is. A balanced RWD build without the help of rear-aero can be created easily. I did ~25 laps in the Monthly Rivals with the C8 and it just feels like that “standard” issue, nothing car-specific.
It surely is no 911 GT3 RS4.0 that is having problems with its suspension since it was introduced years ago.
Great, it needs some research but I can’t find people for it. It’s always better with more ppl. What about creating new thread for it? It’s Forza steering so if we somehow solve it’s usable for all Forzas. Sometimes it feels like front tires has too much grip. But I can feel the same problem for many cars but it’s less visible. You steer and car starts to slide which a bit annoying.
I think it’s programming specific to adding a fake skid to the game instead of the real physics for a skid. The fake skid on a hill is maintained by gravity for far too long.
What we know, all Forzas use great and same physics and all layers are above it. So you can’t do anything to the physics but you can change something above. The problem with sliding is completely the same for Motorsport. But Horizon has many other helpers for easy driving. It’s not easy to find it and that’s the reason why I need more people. And Rayne SE is among the best here so we should find everything with him.
Pretty much on the pace of the other good Modern Supercars like the 458, Huracán, 570S or ATS when swapped to AWD.
Got the best results with a “standard” Race tires V10 build. It lacks top speed though.
Maxed out the 7.2R and did a speed-run on “the strip” since thats all this game is about after all. And I think I see what you mean. The C8s front end kind of “flies” in high speed, as if there was something totally wrong with it`s aerodynamic. Ok, so I maxed out front downforce, minimized the rear, even tryed without a rear wing but the C8 still understeers at high speed.
Tryed to lower the front end a bit, stiffened up the ARB`s a notch and reduced rear tires to stock 305 widht. Rear allignement set to 1.5 to reduce grip. All this reduced the plowing a bit but the problem is stll there.
" It surely is no 911 GT3 RS4.0 that is having problems with its suspension since it was introduced years ago…"
Really? Took it for a spin after adjusting the setup to about the same specks as the C8 above, exept for 3.55 gears & 12.5/14.5 rideheight. Absolutely nothing wrong here, rides like a dream. And unlike the C8 this one takes high-speed turns like a dream, even without a front-wing.
If you do not know how to setup a racesuspension you`ll be wasting your money. Go for a sports-suspension instead, they are pre-set. Some race-suspensions might be closer than others, but most are just calculated by some blind “program” and are crap out of the box.
I would have uploaded some tunes if it weren`t for this stupid file-limitation. Tuned about 100 cars, have to stop now
The car steers fine for me, almost like the Ferrari 599XX Evolution, it steers at high speed on AWD. On RWD it spins like most cars in FH4. It’s that fake skid where you lose traction for no reason.
Yeah, you can say it that way too. Something strange is there. It’s OK in Motorsport because when you slide no stabilization kicks in like in Horizon. So you rather don’t slide in Motorsport.
OK, that could be something. It’s a next research topic.
