What's your recommendations, I plan to buy h&r springs for the car
Most spring replacements will make the car handle
worse at the limit. They emphasize drop over increased roll stiffness, because much stiffer springs are uncomfortable. And to properly handle stiffer springs, you need matched dampers.
If you really want to track your car, save up for coilovers (and I mean good ones, not the cheapest thing you can find - think Ohlins, not raceland).
Realize also that any more than an inch or so drop and you start putting the LCAs in an arrangement that will actually lose negative camber as you roll, which is not a good place to be in for handling performance. They also do bad things for your roll center position, which can make body roll worse (until you hit your bump stops, which is a bad place to be even if it feels really stiff while cornering).
If it's looks you're after, not strictly performance, then go wild.
Personally, I'd start like so-
1. Wheels and tires (especially tires!). Get a good set of summer tires (NOT all seasons) like Indy 500s or PS4s. Realize they're not track tires but will be fine for an HPDE or two.
2. Quality of life improvements. OBD11, homelink autodim rearview mirror, dsg paddles (get replacements, not stick ons), a good radar detector, etc.
3. Seat time. Go autox, go to an HPDE, etc. Best mod is driver mod. (note: be warned you might need new brake pads for the track!)
4. Stage 1 tune. Nothing crazy, but wake the car up and get the biggest tuning mod for your buck outside of tires.
After that, figure out what you want from the car and figure out how to get it.
