Has anyone used or come across these as a trackday tyre? If so, how do they compare with the usual suspects (R888R, Cup 2, AO52, etc)?

Bit faster than an AR1 from what i've heard.

I'm looking to try some for my Clio.

Would be very interested in this evidence

I’m not sure where the faliure of MRF have come from? We’ve used them on various cars in Sprint and Endurance Racing with 0 issues.

We are always on the hunt for a extra bit of time and have been through every semi slick tyre you can think of. The MRF outperformed everything aside from Direzza which we couldn’t see any noticeable difference between. That said they’re a extremely good tyre that outperform the majority in all areas.

I've had many discussions with people regarding these tires and have literally never heard any reports of failures.

We use them on our Mazda MX5 endurance race car. We switched to them from AR1's (also good tyres) and had the following results. Of course these are non-scientific as it depends on track temps, conditions, other factors etc. but this is genuinely my feedback on them:

They gave us, on average, a performance gain of one to two seconds a lap against the AR1. We now hold class lap records at Oulton International and Silverstone GP, tracks where the grip and consistency of a tyre have a huge impact.
They are a more consistent tyre, the feel never changes dramatically in any way, they always have the grip where and when you expect it.
They literally last twice as long before needing replacement (in a racing environment). We would be able to get 5-6 hours of driving at race pace on them before needing a new set. The AR1's lasted roughly 3 hours before we felt like a new set were required.

The reason they are not mentioned nearly as often as the bigger brands are simply because they don't yet have the recognition in Europe and not enough people have tried them. I have asked others about their experiences on them in different types of cars, heavier Porsche's and BMW's for example as well as front wheel drive stuff like clios. I have heard one comment of someone who preferred another tyre they had tried, but everyone else was singing their praises as much as I was. I genuinely believe they are the best value for money track-day tyre around. Worth a little bit more per corner than the AR1's because they will last pretty much twice as long, and many other cars in our championship are now switching to them for this season.

I'm sure most people that have used them will speak positively about them based on what I've seen so far, definitely worth a try if you can get the right size of tyre! MOT Motorsport is the place to check.

Another clubenduro car running MRF ZTR here. Not seen or heard of any failures or issues with these tyres. Echo John's comments on the tyres consistency.

Bold statement. Evidence?

We've raced on them for two years, taken sets way-past what would normally be considered acceptable use and zero failures. Not even the slightest hint of an issue.

Great feedback in dry and damp, grip levels commensurate with any of the leading brands, reasonable cost, no change in characteristic after multiple heat cycles... Struggling to find anyone that disagrees.

We run them in endurance races - 100min, 2hr, 3hr and 12hr. Sorry, that should be we WIN on them in endurance races.

Keyboard warrior springs to mind, are you a regular on the FB Track Time group too by chance?

I used them on my old Mk3 track car and they were great tyres - quite incredible grip in the dry, it's only when it gets really wet that they struggle (as do any of these types of tyres). No issues with them whatsoever, the comment about failures doesn't seem to stack up given the races these tyres have successfully been used in.

They may be a bit of an unknown entity at the moment but I'll certainly vouch for them.

Never used them - but the race engineer who set up my car highly recommended them, plus they are used on the BMW Cup cars. I would have them in a heartbeat, they just don't do a 205/50/16....yet!

Had them on the MX5. Brilliant trackday tyres, best grip in the dry out of 4 different types I’ve tried so far. Very stiff sidewall, lovely consistent feel on turn in and across a fairly broad temperature range. Last well too. Never heard of anyone having issues with them either, with regards to failures.

I found stories on some owners groups a few years ago on Facebook. I'm certainly not lying about it.

Glad though if they have improved their quality.

Have you compared both. My race series has changed from ZTR’s to dz03’s for this year. Not sure which tyre will do the quicker lap

I have a feeling you are getting tyres brands confused.

How else would people pick up that statement?

Not everyone else would have read your posts across the forum to realise what you are like.

Before making such a big statement about a company make sure it's factual. Out of order posting such statements on the basis of some potential Facebook rumour you might have read a few years ago.

Well here is a thing, as I actually did the original testing for MRF on slicks in 2014 at Rockingham when they were first looking to come into the European market, and that the ZTR tyre that people are talking about here only got released in in 2017 for the Civic Cup and in 2018 for the Fiesta Championship it is pretty hard to see how "Owners Groups" have reported many failures some years ago.
As I said, brand confusion.
