Well I did my first and last autocross event and have decided the R is NOT a good autocross car. While I was somewhat competitive I found the R to be just too heavy.<br> There were 6 right turns in the course and I started with 45psi all around. After the first run I upped the front tires to 50psi as the tires were getting scuffed well down on the side walls. After a few more runs I increased the left front to 55 psi but after another run or two it was obvious the side walls were still getting scuffed mid way down on them. I talking sidewall now not the top or near the tread of the tire. I figured at this point the R was just too heavy in the front. <br> I see now why 85% of the other cars there were Miatas and WRX's. I was hanging with a 350Z owner and he had to reduce the air pressure in his front tires...<br> The R was making a lot more power than most of the other cars and my instructor was pretty impressed how I could squirt down the short straights and make up time, never having to leave 1st gear.<p>Just curious if anyone else here has autocrossed their R and what their impressions are?
