Great review Piers! I've reviewed the 963 and found it to be pretty much exactly how you described it. It just feels stable and trustworthy, which is definitely what I wanted given that this is going to be my first season racing in GTP / IMSA. Your comparison definitely makes me feel like I picked the right car for my needs this season. Thanks a lot again for the great work :)
It's funny because on some car I agree with you. But on other I don't. The Acura and the BMW I agree, but on the Caddy and the Porsche I don't. I feel a lot of understeer in the Porsches, way more than the caddy. I feel that the caddy has the best rotation mid corner over the 3 other. Acura best at entry, caddy middle corner, and Porsche really great on exit. BMW like you said, a bit of everything.
I agree with a lot of the things you said, but not others - maybe because the iRacing setups are misleading? The Acura seems to the best car through medium-high speed corners like Road Atlanta turn 1 or Indy Road Turn 1. I feel like it's just generating more downforce than the other cars when the setup is properly optimized for the circuit. These corners are where it has the biggest advantage compared to the Cadillac. Conversely, the Cadillac and maybe Porsche have the advantage in the low speed corners where their midcorner rotation shines. (Although you are right about the Acura doing good with direction changes.)
I don't even drive Prototypes and I took the Caddy. yeah, partly for the V8. yeah, I am American lol I took the default setup Caddy to Spa and at one point ran 3 laps in a row within 1 tenth of a second. HIGHLY consistent. I'm in VR too, which helps that consistency. Still slow. but Consistent can be fast.
Thanks for the video, super informative! I did notice the Porsche having understeer on the medium and high speed corners, I was super used to the Caddy and had some moments in Sebring heh. I have all GTPs except the Acura, but my car of choice personally is the Porsche, I just love that car 😆
Cady for me for all the reasons you said. However, my buddy already has the BMW and doesn't like Cady brand, so I guess we are gonna do endurance races in the Porshe!!!
Regarding Honda it has more in common with the postponed 2024 Indy V6 than the F1 engine. I do think it sounds miles better than F1 ^^ The ARX-06 feels like it has massive turbo lag but once it goes... it just goes.. Very tailhappy out of corners compared to the Porsche. I do think the ARX-06 is fastes but the hardest to master. And Porsche to me feels the safest.
At 3:57, you say based on datas that Acura is 0.5s slower in Monza in T1 What website or where do you find these informations, seems very interesting and I've been looking for that kind of informations for a long time to compare GT3 Thank you ! ✌️
Has the fuel been patched in the Porsche. In Basic Ollies stream last week he found it used a LOT more fuel than the others which would render it at a disadvantage.
Unless I'm mistaken, the higher the brake migration number, the more the brake bias goes forward with brake pedal pressure. So an analogy would be if you set bias at 50% with a brake migration of +5, at 100% braking the brake bias would be 55% and at 1% it would be 50%. For negative, it goes the other way. The exact amount % it moves I'm not certain of. In principle, more brake migration, more rotation on trail braking, less brake migration, more understeer while trail braking. If someone else knows better, please correct me below
@@leinadnagrom I just checked and this is the exact quite from the iRacing Cadillac V-Series.R user manual "BRAKE BIAS MIGRATION This sets how far forward or rearward the brake bias will shift with brake pedal travel. Positive values will migrate the bias forward and increase the maximum brake bias by 1% per click, negative values will migrate it rearward and reduce the minimum brake bias by 1%." So I believe my original statement was correct. The manual can be found here www.iracing.com/resources/user-manuals/
