You have some good advice from Cy here. I was going to ask what your front aero is for the faster cars, but you've already said that you run lower rear aero so it looks like your front must be set to give good grip.
Couple of thoughts:
1) What is your front camber? If it's not zero then give zero or very low a go and see if it helps. IMHO it's easy to go too high as the outside front gains a lot when steering. Feel free to couple this with excessive toe - don't be afraid to try extreme settings just to see what happens, even if it won't be part of your final setting!
2) This is going to be difficult to explain, but when does the tyre turn red/ front grip fail? It's a bit of an academic question since it obviously depends on your driving style! I definitely agree with Cy's thoughts on stiffening the rear, but another thing I would add is to try a harder/softer setup overall. Depending on the timing of your braking/steering inputs, sometimes a softer suspension can feel like it delays the response. This can be bad sometimes, as in "the car doesn't respond quick enough". BUT, it depends what the "response" is!
If the tyres are all white and you've turned in, but the car still thinks it's on the straightaway for a second, then I dare say you want more response, as in the timescale you're talking about the tyre may only be doing 50% of what it is capable of - you want more so you can turn in!
If the tyre goes to insta-red then you're getting the response too quickly, better to tone it down a bit and have the nose bite in nicely at 70-80% rather than overloading at 120%. This may set it up to go red a little later but depending on your style you may not be making the same braking/steering inputs at that time - when the tyre becomes "incapable" you're not actually asking it to do as much.
The above bits on transient response undoubtedly will be affected by dampers - I've not delved into them that much yet beyond general stiffening/softening but there are definitely good guides out there. In my experience springs affect things too with regard to general sharpening/softening response (comes down to spring frequency).
3) Brake balance. More rear brake bias - keep adding it until you spin out! This and/or LSD have sometimes cured a car that won't turn in well.
4) Ride height: I'm not sure if the latest patch changed this, but a higher front ride height would give me a better turn in reposnse (more initial front grip), then less front grip on exit. This was ideal to get the car turned in, then get back on the power - the exit understeer meant you could really hammer the gas pedal without worrying too much about the rear spinning out. Chuck it in, aim the nose just inside the apex and then engage warp drive!
At high speed with aero I'm not sure if this still applies - using the N24 on SSRX I found that a high front gave general understeer at high speed - but then again the corners are so gentle that it probably wasn't the best place to test sharp response!
5) Driving style: You've mentioned that you turn in quite aggressively. If you're not comfortable with taking things more gently in general, try changing your braking/steering timings i.e. feel free to chuck the car in but try changing the timing of your brake release, or even start the release at the usual time but try jumping off them suddenly vs blending them into the corner (like you would with textbook trail braking). Some cars don't turn much and then with a sudden brake release the front tyres dig in like a spade.
6) Bodges (not great but if all else fails):
Increase rear camber until the rears become ineffective - you'll suffer in other areas though - not ideal.
Hammer the throttle after brake release to slip the rear tyres as the front are going red, turn in extra early as you'll basically be 4 wheel drifting through the corner. You might need to shorten gear ratios to get the rears to break free. Basically crippling the rear tyres, but at least you choose when to do it unlike with excessive rear camber!
Would you mind posting settings/tyres/desired track for the Mazda? I'm not on GT6 much but if I get some time I'd be happy to have a play myself to see if I can get anything to work. EDIT : Tree'd by
@DolHaus - good ideas.
