MRF tyres?

[slime bomb]

Has anyone heard or had any dealings with these guys? Looking at getting some fresh rubber for my 420r but supplies are getting very low.

Not a Caterham but I use MRF ZTR's on my Mazda NC1 Turbo when I'm on track.
I've found them to be a very capable tyre with excellent dry weather grip. I've not tested them in wet conditions as I usually put my road tyres/wheels on when raining.
A lap or two ensuring they're warmed up then send it without issues for me.
An excellent tyre.
