what doesn't surprise me is that he kept his GranSport, as it was the Goldilocks version of the C7 in terms of handling. |

Because of your post, I might reconsider the M6. 44 pounds is an unusually small weight penalty for going automatic compared to many other sports cars; someone else on the forum said that is a 1.5% worse power-to-weight ratio for the A10 vs M6. I have seen one very seasoned champion autocrosser say that consistency is the key, and for that reason he recommends automatics to minimize the risk of error that will screw up a run. Have you seen other autocrossers who are similarly enthusiastic about the A10? You don't feel that it's shifting too often on the autocross course? If I'm reading you correctly, whatever negatives there may be are far outweighed by the positives of always being in the correct power band wherever you are on the course. |

There are only around 4 competitive tires for SCCA street autocross classes the last time I checked. The copper free brake package prevents you from running 18" wheels (or at least some of them) due to clearance issues with the caliper from what I've read so make sure that your desired tires are made in 20" or 19" diameter in the correct widths beforehand.

The ice mode issues are overblown imo, but quite real. I have an '18 and haven't once experienced it, and while I'm not national level fast I'm not slow either. We also have a national champ who is driving a '17 SS and he has no issues with it either.
It seems related to the driver's technique and it can be mitigated. It's also related to the course, in general if you hit the brakes and the car senses too large a differential in wheel speed from right to left it will engage "ice mode". If one side of the car is on a lower traction surface and you hit the brakes hard it can cause the car to spin. If this happens as a result of the right side of the car drifting off the road or into an icy shoulder it can result in a spin into oncoming traffic, which is bad and the main reason ice mode exists. We have one driver in a GT350 who has experienced ice mode and left-foot braking sent it into limp mode which required the battery to be disconnected so it would reset. I've heard ice mode happening with plenty of other brands as well. GM hired an engineer to better tune the ABS and these updates went into effect for the '19 model year, so it is true the ABS is improved in '19+ cars.

I will say I do get a lot of hate from manual guys - granted these are my friends, we have to give each other trouble - lets just say they have gotten tired of losing.

I have read about some folks running 19 inch rims square, which is what I suppose I would do eventually but as a beginner I think I would just stick with stock rims and tires until my skill level warrants spending some extra money. I'm definitely going to save this thread for posterity! Lots of great information. |

Kudos to GM for spending the money to make that change. There is a lot to be said for driving a car where some of the engineers designing that car are enthusiasts and show up at the same events you do (The Performance Driving Team), as is the case for the Camaro. |

Fast Autocross Tire Abbreviations: Falkens = Falken Azenis RT660 Yoks = Yokohama Advan A052 Rivals = BFGoodrich g-Force Rival S 1.5 Stones = Bridgestone Potenza RE-71R (discontinued but stock may still exist for some sizes) As a beginner, you should definitely enjoy the car for autocross on the stock tires! If your goal is having fun, there is no need to get different tires. I just wanted to point out some of the things to consider if your goal is to be competitive with the car. Driving autocross courses with the traction/stability control off was a low risk way for me to gain a feel for the car and confidence to do the same at track days. |

Diff tune is NOT legal for street class autocross, but is legal for CAM-C which you can be competitive in without doing much, honestly street class usually beats CAM-C in raw time despite CAM-C being much more open, sooo yeah. Quote:
I would really recommend just going M6. Shifts take time, and the 1LE has more than enough power where you will be modulating the throttle most of the time anyway even just staying in 2nd. I'm curious who this "seasoned champion autocrosser" who recommended automatic is. I do think if you're not taking it seriously automatic is probably not bad but you seem like you really do want to take it seriously and have the best of the best. That would be manual.

I will take it from a friend who is a top NASA, Optima, nmca and scca autocross champion that runs his own top performance shop and runs and tests cars we use. He said no to the automatic. |

To be honest I'm more worried about the oil pump issue than about the valve issue. A number of members here have suffered an oil pump failure over the years. Quote:
