I drive a 1LS V6 base trim with 6-speed manual. To this day, I have done 9 track days and 4 autocrosses.
Key points of the V6 base chassis:
- If you have 18 inch wheels, the 245/50R18 size doesn't offer many performance tire options (P-Zero - okay but overprices, Continental Sport Contact and Bridgestone PotenzaSport will literally melt). What I did is buy take-off 20 inch wheels of a Camaro SS, which unlocked me many more performance options (but still no 200TW tire).
- Single-piston brake system. Since the brake pad footprint is small, you will generate a lot of stress on the tiny brakes. In addition, the aftermarket pad options do not have many track-ready solutions. Remedy: 1) go with OEM pads BUT watch for brake fade (not recommended); 2) buy the 4-piston brake option from GM ($$$); 3) put these pads from Dynamic Friction as I can attest they will withstand moderate tracking (front and rear)
- Engine. While I did not have massive failures, I have had one crankshaft position sensor and one thermostat go out on me. I am not sure if it was due to racing, driving like a moron, or due to maltreatment from previous owner, but those were simple fixes covered under warranty. Plus, you'll eventually feel like you should upgrade to an SS for more power

- Suspension: 1LE chassis has the SS suspension bits, but the non-1LE is still a very capable machine from base. If you look at the lap times tread in this forum, there is a V6 1LE fellow in California, and our lap times are within 1--2 seconds of each other, and on one track I am even ahead, haha. Also, do yourself a favor and go to a good alignment shop and ask them to put anywhere between -1.5 -- -2.0 degrees of camber up front and -1.2 -- -1.5 in the rear. The car will handle significantly better.
