Trade for an AP1! j/k

See Red_MX5's post above about maintaining overall balance. Most cars tend to move form understeer towards oversteer as speed increases. So quick turn in may be great for autocross, but twitchy on a track or sweeping road.

Try increasing front tire pressure in 2psi increments. I run +5 front for autocross or for lower speed (60 mph) mountain roads. Works wonders for turn in and for overall front grip.

 

X-Brace. Makes the car shudder less on bumpy roads, and, makes turn-in a bit quicker. I have Rick's - very happy with it.

Other things to try:

Tire pressure. A bit more usually adds stiffness to the footprint and makes it plant better, good for turn-in. Try 34 measured cold (all the way around, but especially in front).

Alignment, have it checked, if you haven't already - most cars have different settings (all within spec) for each tire out of the box. You can also choose custom alignment specs for additional handling. I don't know too much about turn in but I think going to just a tad more castor might help. In any case, get left and rights set precisely the same, instead of the kinda random variation you'll find in stock form. Also, use a bit less toe-in for increased turn-in in front especially, but rear too. (Too little though and you'll start to sacrific straight line stability especially on roads with bumps or features.)
