Well the season is over and I just took off my 315/35/18 Hoosier A7s to see how they had worn.
I am more of a data oriented person so here are some facts on the tires and how I managed the wear through 2016
Settings
Cross rotated after every event
Flipped left to right after the 5th event (see below)
They are on a 2008 Mustang GT with significant weight reduction
Car weight ~3200lbs. 4x 18x10.5 Enkei PF01s 10mm Spacer up front
-2.9 Camber F, 0 Rear
1/16th toe out
7 Degrees Caster
Amelia Island Airport is particularly hard on tires
Autocross and Track day runs
(6 runs) Amelia Island Airport
(5 runs) Florida International Rally and Motorsports Park
(6 runs) Amelia Island Airport
(6 runs) Roebling Road Raceway
(10 laps) Florida International Rally and Motorsports Park - Track day
(6 runs) Amelia Island Airport - Alignment out of wack
(6 runs) Amelia Island Airport - Spin out
(12 runs) Florida International Rally and Motorsports Park - Spin out
(4 runs) Brookesville Airport
(15 runs) Amelia Island Airport
Wear better than the A6?
Yes, without a doubt.
~66 total AutoX runs, 10 track day laps. VS ~61 Autocross runs on the A6
They also have almost no drop off. The A6 had, in my experience had significant drop off near the end of the tire life. (edit: They still had drop off but not as pronounced, at least in autox)
To also add the rears have at least 6-12 runs left in them. The fronts were most likely nuked due to doing 15 runs at the last event.
Worth the cost vs Street tires?
Probably not. They do mask some errors in driving and take longer to master. I still have much to learn. Though to stay competitive in a Mustang they are a must in my opinion. They were $1.722 shipped vs $1,358 for BFG Rival S 200tw street tires. So for ~$400 you can go a few seconds faster but sacrifice wear and obviously having two sets of wheels/tires.
The cost per run this season was $22. Haven't run street tires in awhile what was your cost per run? Write us!
