yer that is one of the problems is getting the heat into the compound to get it to grip up fully.
i can talk to the people who are the main supplier for these tryes to see what they say about the hard compound.

To be fair even the hard compound on the silverstone softer than the 888 I think.
I will give Them a ring some point this week, busy today and tomorrow, but they wanted me to ring them after my trqck day tomorrow at snetertton, to see how it went.

Danny these are a hill climb sprint tyre the silverstone type RR, so they don't like doing long runs.
They will last long if you use them correctly, not going out longer than 15 mins at a time.
If they are ran too long they start to kill the rubber which wear them faster.
The harder compound will work better if you plan to run for longer say 30 mins.
But hill climb and sprints racing is shorter, which is what these are best for.
Due to the way these heat up and work they grip up straight away and offer so much grip and turning in too due to the construction, which make them a very good sprint hill climb trye.
They are used in a closed competion track racing. But the races are only 15 mins long.
So if you get medium compound can only really do 15 mins at a time
Harder compound should work better on longer runs if that what you do.
I'll ring them get them to email me all the informationon the trye.
I not a trye expert so I get some better information on them.

I know enough about tyres and their degradation Andy
Trust me, if you want a tyre purely for trackday use and want serious grip, grip that even the best road legal can give then get a hard compound slick.. I guarantee they will last you ages. The only reason people in Motorsport go through tyres is they need they need to save that 2 tenths a new slick gives.

Danny never said you didn't, just stating what I have been told.
Yer I know harder Full slick will last longer, it all down to the compound rubber that is used on that trye.
I used the medium compound because they didn't know if I could get the hard compound to work on a light Saxo.
But the way the medium is heating on mine I think there be no problem with there hard compound slick tyre.

Alright mate.
He tells me that the harder compound is an endurance compound that is used in the far east for 24 hour races.
Would have to spend more time warming them up than say others.
The medium which is the one I have is the race compound so wear faster Basiclly he said if you do long section on a track day, that the hard will last longer and be the one to go for
If you defo want a set they are going to double check but 480 delivery for four is the price.
Pm me if your intrested.

r888 vs slick duration
i ve exprienced only the hard componds s9b from michelim .
they hard to get to ideal temperature but yes they are suited for endurance circuit racing...
they manteined good all over the way...the r888 tyres are very good on rain and heavy rain.
dont even compare the performance off the two tires theres alot off difrence.
at local timeattack events some even proibits the slicks--"because off big advantage..."
iff we talking abaut 15 diameter tyres ...not a fortune they cost
1270EUROS the set off 4 tyres..is this a lot for full race set off tyres??
Bruno the L-plater..
VRUMMMMMM....

I know that 911 cup tyres are soft compound slicks for short races. These are only optimum for about an hour of running (in total, not solid time). After which they start to blister and the shoulders rub off. This drops about a second off of a brands hatch indy time! and at £1200 a set slicks can get quite expensive. The other tyres i have run are dunlop slicks for 24 hour racing. these really put up well to the abuse but we still didn't double stint them much. At hour and a half of running at most they did pretty well. ended up going through 72 tyres lol. But i guess the main point here is that as soon as slicks go past their limit of heat cycles etc the performance really drops off compared to an e marked semi slick

..cont..
hi...
i ve not the same opnion...
for saxo , i mean for a a very light car ,the hard compond slick will last a lot more than r888...
we do 25 minutes x7 times at eatch trackday ...should last a full season it near optimum condicion.
how many trackday you make whith the one set off r888...less !!
how good are realy the r888 at 5 or 6 full trotlle lap?? bad they overheat you to manage very hell
dont take me wrong i love r888, for rain useage.

I was stating that once slicks go past their limit their performance really does drop off compared to a road tyre that will slowly degrade and it's performance in a similar manner.
a whole season? jesus that's good going

Try the Silverstone ones and see how you get on?
What torsion bars size do you use Mr sexy_gt? Raising the rear end a bit will help to reduce wheelspin.
I can launch off the line with no wheelspin on slicks. (see my sig)
