I've spent years tracking KDM platforms and the G70 is a beast, but it carries a lot of weight. Everyone talks about engine heat, but in my experience, the transmission is the hidden bottleneck. I remember my first real summer session... by lap five, the car was shifting like it was underwater because the fluid was cooking. Tbh, it was scary. If you have $2k left, I'd focus on these reliability pieces:

• Transmission temps are critical. I'd install a Burger Motorsports Genesis G70 3.3T Transmission Cooler Kit before you even think about hitting the track. It saves the 8-speed from going into limp mode.
• The stock brakes wont survive Florida track heat. I've tried many setups and EBC Brakes Racing RP-1 Track Brake Pads are a solid choice for staying power.
• Dont forget the fluid. Grab three bottles of Motul RBF 600 Racing Brake Fluid 500ml and do a fresh bleed. High boiling point is literally a safety requirement.
• To handle that weight, a Whiteline 24mm Heavy Duty Front Sway Bar makes the car way more predictable. Honestly, staying reliable is about managing the fluids more than the air. I've seen guys with massive intercoolers still get sidelined because their brakes caught fire or their trans overheated. Better to be over-prepared when you're pushing this much power.

Building on the earlier suggestion, honestly I'm super satisfied with my Mishimoto Genesis G70 Performance Intercooler. It works well and leaves plenty of cash for other essentials. Since you're tracking it, you gotta grab these too:

• NGK 97506 Iridium Spark Plugs (gap them tight)
• Burger Motorsports Dual Billet Oil Catch Can Keeps the valves clean and prevents knock. No complaints after a year of hard driving tho.

Florida heat is brutal for these 3.3T engines. Over the years, I've seen plenty of guys struggle with soak after just a few hard pulls. I think an upgraded intercooler is your absolute first move. Not sure if you need the massive race cores yet, but IIRC, the stock unit heat soaks almost instantly... I'd probably look into some better plugs too.

Regarding what #2 said about "Building on the earlier suggestion, honestly I'm super...", which track are you hitting? Sebring vs Homestead makes a huge difference for thermal load. My buddy once took his 3.3T out to a summer event near Orlando without much prep... it was painful. His IATs spiked so hard the ECU started pulling timing like crazy. He ended up stuck in the pits with the hood up tho. Just be careful.
