Got a track related question? I'll try to answer.

[megamarines]

For tires on a consistent day to day use as well as track duty, what is most recommended? Looking for high end grip in each use and am willing to use race tires. Most reviews are back and forth for anything I seem to like.

Issue: rear end kicks out a bit more than I would like under power - taking friends along with twins they all mention they can get on power sooner than I can during sweeping corners however, putting down power for me at around the same spot puts the rear out more than I would like

Setup:
-Ohlins R&T at 4F/5R
-stock sways
-camber -3F/-2R
-Toe 0F / 1/16R
-MPSS ~5 track days

Hypothesis:
-Tires could be heat cycled out
-could dial in rear to be softer
-could try stiffer front sways

Thoughts?

Track or autox? If track, which track and which corner(s)? What tires are they running?

You should get logs showing actual times through a section vs just getting on the power sooner. You could easily go WOT much sooner just by entering much slower.

@wparsons TMP Turn 1 and 3 are most troublesome at this point. MPSS, 245 width with about 6 days on them.

Anything deviating from critical would make the rear more loose.

Too much damping means a loose rear from hopping. Too little damping means a loose rear from weight transfer.

I'd recommend you stop using "stiffer" and "softer" for damping.

The reality is, you're not giving me enough detail for me to dissect the root cause of your problem, so I'm giving you my educated guesses based on common Ohlins R&T problems.

Thanks for the input - I recognize that there are many, many variables at play here and definitely lots for me to go test next time at track as suggested by users above. Thanks for the "best guesses" - that's all I can ask for!

I tried out the Toyo RA1s which i've used in the past on street/track cars.

I found that the R888s were a better choice for me on my BRZ. Really loving them as a street and track tire. So far they are holding up well for me in street/highway driving and on track they have lasted about 10 hard days so far on track and aren't coming apart yet!

Before you change anything at all, I would go for a ride with the friend(s) that say they can get WOT sooner and look at their entry and apex speeds. If they're entering and apexing slower, they're likely far enough below the limit that they can get away with being way earlier on the gas.

It could also be the line you're on, if you're trying to go WOT before unwinding the wheel and you're right near the limit. They might be taking a later apex and straightening out sooner.

How loose is the rear getting? Is it just rotating a bit under power, or is it actually stepping way out?

R888's and RA1's are no grippier than RS3's, and R888's heat cycle out WAY faster (typically long before the tread is gone).

If you want a fast R compound with tread, get the Hankook TD's.

Never used the Hankooks so once these R888s are done maybe I'll give them a try for this winter. (car goes to FL for the winter HPDE/vacation season).

Am I missing something? I can't seem to find those even on Hankook's website. I see them on the international site but not the US site. TR doesn't appear to carry them either Also they don't come in the size I need! Argggggg.

I know of one localish shop to me (it's about 1.5 hours away) that carries them, not sure if they're imported from Japan directly though.

Maybe shoot them a message to see where they source them?

http://www.pztuning.ca/

The owner has been in the US running a few Global Time Attack events as well.

What size are you after? Also check the compound if you do source them, they come in three different options.

Another option is the Pirelli Trofeo R's.

Roger Krause ships a lot of race tires.

Discount Tire Direct has them, but in limited sizes.

Rumor is that the TD may be superseded by another tire already...

I thought it'd be someone I knew. Not that many people tracking 86s in Brisbane that I haven't met

If they're purely track tyres, then I would suggest a proper r spec tyre. I don't have any experience with R specs on the 86 as yet, but I'm encouraged by what Josh has been able to do on the Hankooks. Nittos might be another option at a comparable price, or Kumho V70 or Toyo R888r.

Looks sweet though, and handling is still phenomenal. Might lose a little top end in the straights though.


RPF-1's are probably the best price/weight deal, 225 width tires are probably more than enough for an NA car. Any high end summer tire is going to do well on the track (especially compared to stock all-seasons), so pick which one suits you. Pretty sure a +35 offset is fine with a 17x8.

LOL, the gunmetal is why I am buying 17x9 from Oakos. I also will be concentrating more on autox than track for the next 2 years so it was a dealbreaker. If I get to the point where I can buy alot of track time then I should be able to afford 17x8 for better times.
