That's good info and a solid temp range for coolant. What ambient temps have you been running in? The event I will be testing at in 10 days should be in the 80s, possibly low 90s. I'm curious to see how the full package reacts.
I didn't get my FL5 until mid-summer last year, and didn't have it on track until the fall, so I don't think it's been on-track above 80-85°F yet. Since I'm in Nashville it definitely gets hotter than that, as we will touch close to 100°F in the summer with moderate-to-high humidity, so I very well may run into an issue, I just haven't so far.
That's reasonable. My plan is to run pwr intercooler, radiator probably get HKS oil cooler because I love the cut out bumper idea. Might try the cooling plate and run as much e85 as I can. Waiting on the mugen hood coming this winter.
Didn’t notice you are running RE71RS.Going back to alignment, I dialed the front back to around -2.8° for negative camber.
After I did that I thought I'd take a picture of last year vs. this year, and as you can see from the labels this isn't a perfect comparison, but the previous set (same size, same wheel width, same offset) still did similar sessions on the front + additional sessions on the rear, and still isn't worn through.
that wear pattern of the one of the left looks awfully like toe wear.Going back to alignment, I dialed the front back to around -2.8° for negative camber.

Your 8 session front looks like my Trofeo R after 7 sessions with -2.75 camber. Mine wore out the inside, similar to what you’re showing. Previously, at -1.5 camber, I had a similar outcome on the outside of a PS4S.Going back to alignment, I dialed the front back to around -2.8° for negative camber.

What other cars are you referring too, and what alignment lasts the longest for you?Your 8 session front looks like my Trofeo R after 7 sessions with -2.75 camber. Mine wore out the inside, similar to what you’re showing. Previously, at -1.5 camber, I had a similar outcome on the outside of a PS4S.
I’m at a loss on how to get decent tire life on track. Stock camber I destroy outside edge, more negative camber and I lose the inside. I’ve never had any similar issues with any other cars.

It's possible, I don't know enough about the changes of toe with load on this platform, although I don't know that it would be much different than last year? I ran the same tire setup, just with different springs and dampers (and with my rates I should be better-controlled vs. last year). I do know for sure I struggled more with corner exit power delivery which definitely would be consistent with the wear, so we'll see how this weekend goes and go from there.
I had track oriented alignment on GT-R (2 different ones) and Lotus Evora with negative camber and I never had any accelerated or uneven tire wear like I’m seeing with the FL5.
Was this with rotation? Are you making a lot of power? With rotation last year and the lower camber (~-2.5° front) I actually got pretty even wear on all 4, with basically full use of the tread (as you can see in my picture).Your 8 session front looks like my Trofeo R after 7 sessions with -2.75 camber.

What is your rear alignment set too?Going back to alignment, I dialed the front back to around -2.8° for negative camber.

It's never been adjusted, just verified with my gauge / toe plates, so it's still at the factory setting, just lower - I didn't want to pay for a formal alignment until I stopped messing around with the suspension. But, it's about -2° camber with 1/16" total toe-in (I'll run somewhere between 0 and slightly out on toe once I actually get an alignment).
