Wow. That's impressive!
Making a strong commitment to the gas pedal on corner exit is not easy. But it's fundamental to fast lap times. Your line coming out of the corner is the key. I would expect you'd want to take a slightly different line on some corners with the GT3 than the GT4 to do what's needed. Joe, I suggest you get the first of Adam Brouillard's "The Perfect Corner" books. He's not the best writer but he's really smart and he has some great tactics to improve one's driving. They are unlike any other books I've read on driving/racing technique.

Thanks for the tip! Will look it up.
How do driving lines differ between the GT3 and GT4? I would expect that generally the GT3 might benefit from slightly later apexing because "in theory" a rear engined car might have ever so slightly worse apex speeds but better exit traction. But in practice, not sure...

[/QUOTE]In practice, I drive the cars and the line about the same. I think a really good driver knows how to extract more by changing the line slightly.[/QUOTE]
Assuming the 2 cars can go through the corner at the same speed, and they should, you want to choose a line out of the corner that allows you to put the power down ASAP. The GT3, with more power, might require a later apex in order to get back to full power right away. The bottom line here is that, no matter what platform you are driving, you want to figure out a line that will allow you to get on full gas from the apex out.

Got it. LOL

+1 on reading these books. They've brought clarity to my driving and instructing, and have made me faster. Grasping the physics in these books isn't easy (feels like working through a college course rather than just "reading"), but I've found the content of the books to be consistent with what winning pro drivers are doing.

Same tires, prep, aero effect, and about the same weight to tire ratio (GT3 heavier, but slightly wider tires), physics says mid corner speeds should be almost the same. If they aren't, the driver just being more comfortable in one car over the other would be more likely than any other explanation. Static mid corner dynamics shouldn't be affected too much by the differing rear suspension designs.

Don't get too hung up on mid-corner speeds but look for the line that allows the earliest WOT. Depending on car dynamics you can take an earlier apex, add power, and keep the nose sliding around the apex curbs.

Agree with bill
When I am behind a well driven gt3 they hold me up in the corner and I can stay with them after exit or on short straights because I (can) commit to WOT earlier. Take a look at my latest fast laps behind the gt3 at wgi that I uploaded. Wgi is a real power track but I am able to really push the gt3 till he has to give me the pass. ( and me pushing him allowed me to set me fastest laps of the weekend; I love chasing GT3s)

There's a quick follow up in my mind related to the above answer. I understand that the stiffer springs and DSC are equivalent for prevention of excessive dive under braking. Does your either/or suggestion mean you also believe that the two are equivalent as far as getting even tire wear are concerned as well??
I thought from reading through the thread to this point that the spring upgrade was starting to look like the best-known-method for getting more even tire wear but if DSC can deliver the same on that front it'd be a less intrusive mod which might be a pretty attractive option since it's near enough DIY and easily reversible.

I don't know how much either helps with wear individually. I will say the neither was enough until I bumped my front camber up to -3.2.
