There's a local race shop I get tires from that runs some tallll tires on the rear end of their GT3/4 Clubsports.

I almost forgot to mention Nankang also has a Brand-New 200tw tire, the CR-1, that is looking promising and will offer a 275, 295, and 315 size. A few small retailers are taking pre-orders on them for November/December as well.
On a 10.5/11 stagger I'm liking the 295/315 A052 option or a 305/315 Rt660 option. Maybe also look at 285 square RS4's on those wheels.

Providing its not discontinued, the AD08R is also available in a 265/295 stagger. Probably the slowest of all the options, but will last the longest.

The RE71R isn't really available in my sizes so I can't comment on that comparison. The Rival S lasted longer than the R888R while being more predictable and easier to take to the limit, hence just as fast. They also didn't get greasy as they wore down. They handled heavy rain on public roads just fine. I did Cresson in the rain on them and was satisfied with how they communicated what was happening on the front axle.

Some have said the Rival S is "too soft" for a big heavy car like an M3 or Corvette, but I think those people have never even used said tire. Quite honestly, if Toyo wasn't a partner with NASA (contingency), I would probably go back to the Rival S.

The biggest issue I see with the Rival S is that the A052 exists, though not for my sizes.

The only people I know using Rivals are those that need the little 15" sizes they sell or giant 335/18's for their Amercian V8's. lol I would be interested in the 275's, but there's also so many options in 275's that I prefer to where they're not really worth it price wise when the Bridgestones and Goodyears etc are cheaper.

Exactly. My only other choices are R888R, NT01, RR, and R7/A7.

I'll never run R888R again, NT01 seems pointless given that the RR is available, and obviously the purple crack is in a class of its own. The Rival is really the only streetable tire of that group.

Tall sidewall. Looks out of place but I’m sure there’s a good reason for it and looks aren’t everything.

I had an odd thing happen with the Carbotech XP20 pads on a rainy track day after it dried up. When the pads got hot after several hot laps, it felt like there were pad deposits on the rotors. After the rotors cooled, it was back to being perfectly smooth. The only other thing I could think of is ABS activations but I haven’t been able to check.

Even with all the extra precautions of wearing masks and gloves when going out, changing into clean clothes when coming home, only getting groceries delivered, and occasional food takeout, I somehow caught the coronavirus. I’m 4 days in since my first symptoms and the worst part is the never-ending headache which is only getting worse by the day. It makes it really tiring to do anything.

Do whatever you can to avoid this virus. Stay safe and healthy.

I think they look great.

Oh crap that's surprising. I've been very cautious too; life is pretty much work, hugging dogs, and track. Food either cooked myself or delivery for ~50% of meals.

I hope you get well soon

They don't make anything else wider than a 315 in 18" diameter. I would've preferred 335/30R18 which is what I ran on the Rival S and R888R.

This will change the aerodynamic rake of the car a bit, by the way.

Ah that stinks man, hopefully you can rest up and just get through it. Will make your next track day that much sweeter!

What is the typical oil change interval for track days? I swear I’ve seen a thread about this topic before. But somehow I can’t seem to find it.

Anyways, I changed my oil back in April this year. I’ve only put about 4000km including two track days on the car since. Just signed up for two more track days, one in September and one October. Should I do another oil change now or I’m good for two more track days? I only drive the car on weekends, so between now and October I’ll probably only put another 2000km on it. Then I’ll likely park it for the winter and do an oil change in the next Spring.

It's probably fine to just do it again in April. The car has a huge sump and the 10w60 oil is very stout.

I used to do it once a year which was around 7500 miles and maybe 6-8 track days. Never had any issues on the analysis reports -- stayed in grade, negligible fuel dilution, and wear metals held constant.

I wonder if it's drag-car style stuff? Big sidewall so the tire can flex more upon acceleration, for launch grip? It is a beast

I do it at every 6-8 hours of track time in both M3s (E92 and E46). Maybe overly cautious, but it's worth it.

Then again, maybe not considering what my E46 did...

[kyippee]

Cool, I've been about the same. Every 6-8 hours of seat time on track, which is at 3-4 HPDEs. Used to do it less often but I also was driving the car much more softly then now. Having a motor go ka-boom on me also makes me more cautious now..

A guy at a local shop said that a HPDE was equivalent to 1,000km or 600 miles of normal driving.

So I just do mileage since last interval plus the equivalent number of HPDEs until it hits my normal change internal (7-8,000km or 4-5,000 miles).

[LeveragedTiger]

On another note, does anyone have Vibra-Technics engine mounts and noticed that they've degraded over time?

I have the Street versions and there was like no vibration whatsoever when I got them, but it feels like they're beginning to vibrate more as the HPDEs and mileage increases. Could be something else, but it's my first guess.
