Long time no post...
I have done a few autocrosses at this point. I have a regular codriver now which has helped. Without a codriver it would definitely be a struggle to get heat in the 295s. I can't say the tires are incredibly different but the car does feel good and we appear to be using them completely. They seem to like a little less pressure than the 275s.
Last event was Pocono, a 2 day event. 1rst day, my codriver ran up a curb pretty bad and came back with a dangling exhaust. we wired tied it back up and kept running the car. It was noticeably louder so I knew something was broke. Turns out the weld at the header merge broke.

The car continues to be very reliable and a ton of fun. Having a baby has very much limited my time for autocross but this car has been a blessing to get out and not have any major issues.
