Looking for some advice really.
Currently got Kumho V70 track day tyres, love them absolutely brilliant but not in stock now till next year and with two track days coming up in the next couple of weeks I will need replacements in a week or so.
The only track focused tyres I can find that are stocked in the UK are the Yoko AD08, has any one tried them and if so are they any good?
If any one has another suggestion of a tyre that they have experience of I am all
Prime concern is grip.

Hi Martin
I have Fedral FZ201 on mine which I think are better than R888s. If you want to give them a go I can dig the number of the guy who will be able to sort a set out for you.

Thanks Graham, out of stock, and not due in the country till spring I believe although I have not tried Nick yet, will give him a ring in the morning, I still have his number so no need to dig it out for me.I have Fedral FZ201 on mine which I think are better than R888s.

Thanks, will keep them in reserve, good long lasting tyre the FZ-201 take the grip levels to the next level as do the Kumho V70's which are my preference, the Cerb feels so sure footed on these, the very stiff side wall works brilliantly with the Cerb.Brining this back to life.
My Cerbera which is at Topcats Racing as this month has turned into a larger spend than I was anticipating (due to my OCD and love of LEDs not to mention Im not at DIY level... Yet) has a Knackered N/S rear (Toyo T1Rs all round) I have been told must be changed.
I just got a rear pair of Federal 595 RSRs as was wanting to go to a legal track tyre anyway. Keeping the fronts as the Toyos for now as not sure what a 225/40 would do to my dynamics over the current 225/35?? Please can anyone advise on the 595 for road use in the dry and in the wet please and the general temperament of the tyre. Even how they may work in tandem with the Toyos at the front?
Thanking you all.
PS Gruff its always nice to hear from you as you'll soon be getting me track tuned lol

Despite what the Track Gods say you don't absolutely need to use the same tyres on front and rear, you can vary them to try to counteract a car's inherent behaviour.
However there is one big proviso: the tyre wall must have a similar compliance. I can't remember which way round is almost lethal, but if you get it wrong it will become immediately apparent: You don't need to venture out on track to realise that the tyres need to be replaced immediately, not in hours or days.

Hahahahaha PhotoSHop????What planet am I on?... lol I over looked as I thought all Cerbs had PS? YES I do if that helps mate. Im 2000 mk2 Speed Six, what is funny is my car runs Tuscan offsets.
My spiders were, then I did a straight swap to SP12s which I think are fantastic.
My issue now is the 595 RSR fronts are only a 225/40/18 and Not a 225/35/18 that I currently run so Im not sure what going to 40 profiles would do?
Cheers

Good point about the sidewall..However there is one big proviso: the tyre wall must have a similar compliance.

I've always had mismatched tyres front and rear on my Cerb and it has been OK so far.. Although I do wish to move to the same all round.
In your case Incognegro.. Running a semi track tyre and a road tyre will be a bigger difference.. I'd imagine in the dry the rear end will have loads more grip (understeer) and less in the wet. For track biased tyres I would run the same all round.

Mixing tyre (especially road and semi slick) and tread types is a seriously bad idea if you are going to drive on the limit. Mixing differing compounds for the same tyre can be good though.
What I ended up on mine with was semi slick R888's as they were then but I used a softer compound tyre on the front to kill off the low speed understeer that I inadvertently created by fitting a stiffer front anti roll bar.
the rear matters less because you can easily balance a cerb on the throttle as they have so much power and if they are set up right they are really stable and beautifully predictable in a slide on the limit.
