Just an update. Now that the season is over I'm thinking of next season.
My plan is to stay with the square setup as I plan on competing for points in Auto-x but still will attend a few track days. I'll also be adding a FR swaybar (per stock class rules) to generate some understeer for that safer feeling. I think the swaybar will help the car feel less "about to spinout" feeling. But we'll see next season!!

hey Dave any updates now that the season is over?
I drove on used 615's this season and I got the feeling that the tire was very greasy, especially when hot. Now I don't know how many times these tires have been heat cycled, but now it's my turn to decide whether to get a new set of 615's and see if they're the same greasyness, or add the extra $300 for the RE01R's

Tires...redundant title I know
Time for new tires (stock 06 Z [18's] running in BS in a street tire grouping). Dual purpose tires for street and auto-x. Street driveability isn't too much an issue(i drove on Azenis 615s year round through all of Oregon's rain and some icy conditions).
I was looking at getting the Dunlop Star Specs, but at the same time I am trying to get some wider rubber
If I go with the Dunlop I'll probably end up running a square setup: 245/40 front and 245/45 rear. To maintain the stock size height but will add some width to the front but the rear will still be stock size and I already had linear traction problems.
I've been running the Falken FK-452s in stock 225/45 and 245/45 and have been decently pleased with them. I can continue to run those tires and go to a 245/40 front and a 275/40 rear. Or run a similiar tire the Sumitomo Htrz III in a 255/40 and 275/40.
What is everyone's take? (I didn't want to ask non-autoxers in the tire forum)

I stay with the stock sizes and find a good tire for normal driving. I drive 300 miles a week to/from work. I'll run street tires 4 or 5 times locally during the year when I don't want to change tires at local events.
If there was a street tire class for the Z like the Florida local class, STU2, I'd get the RE01R but I still be changing tires at the event.
I looked at you signature and have to ask. Test pipes are allowed in B Stock out in Oregon?

I hav not run the RE-01's on my Z but my brother (drives an STi) just switched from RE-01's to star specs and says they are comprable in performance. However, the star specs don't wear as well as the RE-01's.
I had to run mismatched tires at state, because of availability issues, (XS's on the rear and star spec's on the front) but the XS's seem to be better than the star spec's so far.
I have ran MX's, 615's, BFG KD's (not the KDW's) star spec's and the XS's. Out of all those, the XS's are the best tire I have ever ran on my Z.
615's were my least favorite.

So, first integral of velocity, but not the actual force.
As opposed to a accelerometers connected to the vehicle.
(I used to work in space & defense, and have extensively investigated GPS technology -- including military-grade GPS hardware. I've also investigated accelerometers, and direct measurement accuracy of 0.001g is easy -- and inexpensive)
