Make sure you push it hard enough to spin (but spin in a safe part of the course). *** engine slot car has handling characteristics at and past the limits that are counter intuitive to a BMW. Turn off PSM for autocross. Much easier to learn the limits that way.

You've picked a fine car...I see years of Porsche adventures ahead. Cheers

The 135i has much more torque and low-end power, while the 997 has the top-end advantage. Around town, the 1 feels faster and would easily embarrass cars with more power. The mag tests show that the C2S has the acceleration edge, but not by much.

Both have great brakes, but the C2S has a firm pedal feel with no play in the movement, something the 135i can't match. The C2S's steering is much lighter, and getting used to the light front-end is a bit of an adjustment. The 135i's short wheelbase made it a handful in tight, 2nd gear autocross turns. If the steering wheel wasn't straight, the rear-end would want to come out quickly under aggressive throttle usage, while from what I can tell so far (and have read), the C2S has the traction advantage from the massive rear footprint and weight over the rear wheels. I'll explore that aspect soon on track.

The seating position in the C2S is superior, allowing a lower center of gravity, whereas with the 135i, I had the seat as low as it would go and still felt like I was sitting tall. I'm a normally-aspirated guy at heart, and while the 135i is about the best you can get in terms of minimal turbo lag, nothing beats the responsiveness of an N/A setup. A sports car has to have a proper soundtrack to go with the experience, and there the C2S is worlds away from the turbocharged 1's muted engine and exhaust note.

While the 1 is more tuneable (370hp with a simple $800 flash) and can be uncorked for better sound, it'll never match the chassis rigidity, engineering for prolonged track use or superior traction of the 997 platform. It's really not a fair comparison, pitting an $89K Porsche against a $43K BMW, but at the end of the day, the 997 is the genuine article and the measuring stick. However, at CPO prices, it's a realistic conversation.
