This was just the last time I went. I swapped my 17's for my boys 15' Slips, but they still had 711's. I had mad traction issues and it all boiled down to inexperience. I only got two runs in, the other was 15.8 with a 2.6 60ft.

My best run to date was on my heavy ass 17's and Dunlop FM 901's was:
60ft: 2.457
1/8: 10.272 @ 70.272
1/4: 15.788 @ 90.22

This last time I put my rear struts to full stiff and I had mad ass wheelhop the first run. The second run I softened them a bit and feathered out the clutch in first gear and had a great start, but I dropped it into 2nd gear and spun right to redline.

Theoretically I should run 15.0-15.2 with those 15's and a good 60ft.

This was all in Las Vegas @ ~2300ft.

EDIT: The 15.7 I lowered my tire pressure on the 17's to 35 and all my struts were at full soft. The 17.5 I lowered the tire pressure to 22.
I've had 5 total runs on the track. 3 my first and 2 this last.
