Great feedback as usual, Ryan. Our local lots are low to medium grip and it feels like I can never use the whole car. One high grip site a few hours away, and the car feels super great. Just need something to have fun with locally I guess. Maybe just get a pair of 18x12 rears with 315 Yoks and leave the car otherwise stock to beat up on CAM folks locally :P

Though I am still on the C8 waitlist and thinking more about moving to it at that point.

Really looking forward to some real big tire testing comparisons between the Yoks and the Falkens.

trust me ive gone in and out of the camC rabbit hole a few times this offseason... its tempting.

Our local lot had been recently repaved and has stellar grip on most of the surface. The grip up in Packwood used to be pretty good, but it's been slowly deteriorating over the years.

I feel like I missed the window of my car having an outside shot at trophying in SS, now that fast(er) tires will be available to the faster cars in SS. Next year is going to be pretty crazy with all the new tires coming out.

I wanted to bail to SSR and run A7's for fun, but the misses is against it, so I'm probably going to do some half-ass CAM prep and roll the dice on tire selection.

I've thought about CAM once or a hundred times. The solution that is to make a list of all the mods you'd want to do. You can even rank them in order of priority. Then put price tags on them and add them up. Problem solved.

I would rather drive the car with the ax rear end programming, I can't see a downside to doing it, it should make the car better and thus more fun to drive. It's too bad doing that and remaining in a street class isn't possible. However, going CAM also allows for 18" wheels of whatever width and offset works best, as well as camber plates, which also isn't too much added cost, plus it helps with fitting wheels with minimal strut interference.

I do get the slippery slope argument though, it's temping to do everything rules allow but I don't think a cam and heads are going to get you much for your ~$10k, so you just have to draw a line on that list and not go past it.

Ethics aside, how would a reprogram of the chassis control module even be policed?

The truth is they really have no way to police it. That said I do know or heard rumors that some street classes were getting top three or so ECUs were going to be read for tunes. Not sure how but the threat alone should scare people.

For our cars, if they wanted they could have someone from the GM team bring a lab top and see if the diff tune is on it or not.

I would love to test the diff tune myself see how the car feels but Id run cam that day. or hope for a test and tune day to run both back to back.

The eLSD tune is in the ECCM (Electronic Chassis Control Module) in the trunk. Unless they have a MDI / MDI2 with the latest GDS2 software, they aren't going to be able pull full calibration info. For the ECM, you really think they'd be able to tell what is tuned? In our drag racing, like Chevy Performance Stock, they swap ECM's between competitors at some of the NMCA races since the tunes are (supposedly) locked, but, NMCA knows some / all of the code locks might just have been broken.

The point is mute since i dont race that way anyway. If other feel the need to well then good luck.

Appreciate that and totally agree. It would be easy to cheat in many ways, but simply knowing the car was illegal would ruin the fun and cheapen any result to me. Easy enough to change to the other set of class letters :P

It would be nice to run them back to back, but it costs $300 to have it flashed and I don't think you can go back (without another trip to the dealer) or disable it (while still having all nannies off).

Agreed on the ethics issue, rules are rules whether you agree with them or not, that's how it is. Also, you're not going to be able to hide 315/18s and camber plates.

In SCCA autocross competition, the answer to this is that any competitor may file a protest against a vehicle. A protest fee must accompany that. In a situation like this where the vehicle probably has to go to a dealership to have its module scanned to verify the calibration, I believe the protester must agree to pay for it and the protested party also puts up a bond to cover the costs if the car is in fact found to be illegal. IOW, whoever loses the protest has to pay all the costs associated with it. My guess is that in 99% of such cases, the person(s) driving the protested vehicle withdraws from the competition rather than pay for a service that they know will prove their car is illegal.

You could always make up a fake TSB to cover the modification you want to do. JK

I'm not sure if the diff tune helped me or not. I have the calibration on a spare module and after installing it I never tried the stock one again.

Something very similar to that has been done at least once. Back in the 90s, Andy Hollis fabricated documentation showing a tow package for his Civic or CRX (I forget which). This supposedly allowed better gearing. But no such package ever existed. He got slapped with a 2-year suspension and the largest fine in Solo SCCA history.
