Well spotted :drive:

easier said than done. Lot to do with feel and experience or seat time. Like someone said, a good sign is screeching tires. This tells you the limits of grip your tire has, given you've chosen a good line. Reiterating what everyone else said, start pushing yourself at HPD events. I.e...learn the lines, drive fast as you can, note your entry speed. If you can turn at 50 mph no problem, try it at 52 mph...etc.

just curious as to how people learn the limits of their vehicles, in this case the CTR.

wish i had an empty track just to play with the handling. but at the moment im just left wondering what i should and shouldn't do.

Seat time.
Experience

These are ideally gathered in the safer confines of
1) Autocross events (low speed for the most part)
2) High Performance Drivers Education events (high speed).

SCCA (Sports Car Club of America) puts on both such events. There are others (some national, some not). AX's cost maybe $30-50. DE events are usually a couple hundred $$. SCCA also has "track night in america" series which is popular due to lower costs and time commitment.

Its a skill to be learned over time. Your car has some very high limits. In most cases, without experience, you will end up doing something wrong / running out of talent and damaging something.

As others have mentioned, "tire squeal" is the primary indicator of going too fast.. But if they are already squealing, then you have to know how to make it stop (if desired) or realize that just cause they squeal doesn't mean the car still isn't under control.

As racer indicated, tire squeal isn't a great indicator of being at the limit. Often the edge of the inside tire will squeal in a turn despite the car being nowhere near the limit of traction of the outside wheels. Likewise, some tires are silent right up until they break away and some are even silent when sliding.

Keep going faster until you hit the guard rail, then go a little slower than that!

Seriously, the one tip that really helped me was to always do all the braking you want BEFORE the turn, then power out after the apex. With a FWD car, you often gain stability (and reduce understeer) as you add more power in a turn.

Also, I’ve sometimes found that I’m happier with VSA turned off on a dry road. Sometimes it can kick in and do something that feels de-stabilizating. In the wet I always leave it on.

I agree with Z06_racer and Racer. Sign up for a local HPDE weekend and most are not that exspensive. You'll start in green group with an instructor and he, or she will teach you about braking zones, turn in, apex and track out
Plus a whole lot of other things about driving correctly on the track and street for that matter.
One thing I really remember from my track days is, smooth is fast

The fastest way through most turns or curves is to slow down...In autocross, we have a saying..."slow down to go fast." Your tires are the limiting factor, but it takes some degree of experience to realize when you have reached that limit. There is a big difference in tire screech and tire squall...once you exceed squeal, the next thing is squall and it pretty much comes immediately...When you reach squall, you are over the top of the adhesion limits of the tires on that surface under those surface conditions. Sometimes you can use air pressure to adjust squeal vs squall, increasing or decreasing adhesion limits. Steering input is another determining factor...slow hands can get you through a corner better than fast hands, as in yanking the steering wheel vs feeding steering in gently as you need it. Smooth is fast.

But, as others have suggested, find an autocross club, get an instructor to ride with you, and learn how to do it before developing too many bad habits. Listen to the instructor and do what they tell you. Most SCCA instructors are well versed, patient, and provide good instruction...

I thought the saying was slow in fast out?

Yep, that's another one, but you have to learn brake/acceleration modulation to properly execute. The first thing is getting students to get on the brakes and slow down before entering a turn. With experience, they may not even have to brake, just a lift to slow entry, transfer weight to the front wheels, then power out...but not by using the acceleration pedal as an off/on switch...learn to squeeze it on...
