Who here has tracked their Emira?

[Blackthought_]

Anyone here track their Emira? If so, did you track the car 100% stock or did you upgrade parts? Particularly interested if you changed out the brake fluid, pads, tires, etc.

Any recommendations for a Cup 2 alternative (can't justify the cost) that is available in Emira sizing? Probably something from the Super or Endurance 200s from here

Not really…Choices are really limited (right now). It’s too bad that the Bridgestone RE-71 RS doesn’t fit. If I don’t go with the Cup 2, I’ll try the Yokohama ADVAN NEOVA AD09 or ADVAN A052…but maybe I’ll get lucky and Bridgestone will size the RE-71 RS for the Emira soon!

I was also considering AD09 but Emira sizing isn't available. AO52 will be overkill for street driving. My aim is 4-6 trackdays per year

Tire Rack appears to have them for $1482 for a full set…

I used an old version of the AD09s in the past. Loved the look and grip. However they were very noisy and rode harsher as they began to wear. Not a real knock on these tires. I would just recommend changing them after they wear and you feel any ride discomfort.

Is this a market specific thing? We have Emira sizes for the AD09 in Japan.

On the other hand, we don't have Emira sizes for A052 (yet).

Good to know. Thanks!

I started going to the track last month. Miami homestead. I'd like to go more. Maybe join a club. I'm trying to get a handle on tire cost/wear.

I have the Goodyear F1s. With track suspension.

I have done 11 sessions over 3 days. The front brakes are gone. The tires look pretty worn on the side. One instructor said I probably have 3/4 of a day left as the groove gets worse.

I can swap from left to right with a remount. Then get about the same on that side, I'd guess.

So 5 days for one set. That is tough. Some guy driving a C8 said he got 8 days, 4 sets a day. That would be a lot better on the $$.

I could probably squeal less in the hairpins.

One good driver said grippier tires get you a better time, but mask poor driving.

I thought the F1s would be out, but maybe they are not a bad deal.

Any thoughts?

It's great that you're taking your car to the track and focusing on building your skills.

Hiring a coach, even for a day, can be a great investment. Alternatively, sharing your videos can help others provide valuable feedback.

• Regarding tire wear, outer shoulder wear is common in track driving but can be mitigated with proper awareness and mechanical care. You're right to pay attention to tire feedback (the squealing), adjust pressures, and ensure your alignment maximizes negative camber up front (around -2 degrees with OEM parts).
• The chunking you’re seeing suggests overheating and over-driving, which is often linked to tires like the F1 (a street-focused tire), which has lower temperature limits and requires cool-down laps to prevent failure. The same applies to OEM brakes. Overheating both will lead to unnecessary wear and costs.

I've run AD09 tires on my 2023 BMW M2, which has more power and weight than the Emira. These tires have a squared profile that helps reduce impact of shoulder wear but need careful handling. They offer consistent performance for 20-minute sessions but can chunk or separate if over-driven. They're a good choice for a car you don't plan to slide around and prefer consistent lap times. They also last a bit longer than other tires like the 71RS, though they’re noisier/harsher.

I haven’t tracked the Emira yet with its Lotus Spec Cup2 tires (240TW), but they’re known to perform well for a lap or two before losing grip and melting your money away. If you’re a more moderate driver, you might not notice this drop-off.

Ultimately, tracking is about understanding your car, your driving style, and how to balance performance with fun. Don’t get too bogged down in the details—remember to enjoy the experience!

Yep, AD09 isn't available in Australia (AFAIK) in the correct sizing but A052 is available. Hopefully that means eventually we will get the AD09 as well

A less grippy tire will last longer on track. Lap times will go down but also the amount spent on tires.

I searched TireRack for "Extreme Performance Summer" . There are only a few that fit. One comment on the ones you mentioned had a guy get three days, like me. The
Continental ExtremeContact Force seem to get good reviews on wear.

I'm not worried about the brakes. I have some track pads on the way. They are easy to swap.

I'm not sure I'm ready for a track only tire. Then I'd need a second set of wheels and a storage locker.

I did two trips to Spring Mountain on the C8 program. So 4 days. They grossly over coach. It wasn't fun until the last afternoon when we switched to open lap. It was mostly lead/follow or autocross. Then a bunch of classroom stuff. To go back no would be 5k for two days. The Miami-Homestead road course is much more fun. No plane ride. But wear and tear on my car. So I'm balancing it out.

This is the RF tire the way it is now.

My buddy at the ski lake suggested a track alignments. Will that give me significantly more wear?

Gross over coaching is a surefire way to not have repeat customers...bummer. My experience(s) have been different but I know exactly what you're describing.

So the Conti ECF is in the same league as the AD09, RS4, and a bunch of other Endurance 200TW tires. You should expect roughly the same wear rate across those tires but their NVH and handling characteristics do vary. I still stick with the AD09 as they are non-directional so you can at least rotate your tires left to right.

Clarifying 'track only tire', almost all tires that have a tread wear rating can be used on the street (have DOT approval). All of the 200TW tires can be driven legally and safely on the streets (in dry and warm conditions). Some will perform better than others in wet and cooler conditions, but none of them should be stored or driven at or below freezing temperatures. I should be careful when using that phrase.

The chart below from Grassroots Motorsports is a rough guide (not gospel) and know they use their track Miata as the test car. Unless you change your wheel setup, we all know that our options are severely limited anyways.

I assume, your track alignment question focuses on tire wear on the street. Excessive toe-in or toe-out results in increase rates of tire wear, more so than camber. So keep the toe specs within OE ranges and just maximize the negative camber to start. When you do get an alignment, try to do it with fresh tires for the most accurate measurements.

If you're running the same set of tires on street and track, you're still likely to wear the outer shoulder before the inner shoulder. If anything, the negative camber helps to balance out the wear between both use-cases. Keep in mind, the Emira cannot get a ton of negative camber in the front with the OEM hardware. In the rear you also don't need much more negative camber than the factory recommendations (you can judge yourself based on the tire wear).

Once you have tires and alignment, the rest is on managing tire pressures and your own driving style.
Lastly, your FR is pretty much done for any track work, you'll see cord soon, if not start to lose major chunks of rubber the next time you go out.
