Im using R888s on my R400, but its more R500 spec with regards to power output. I prefer them to CR500s in the wet although standing water can be pushed a side more with the CR's so better when its actually chucking it down. Never used ACBs, i use the R888 due to cost and amount of times they need to be changed....2 or 3 times a season. If i had some more cash i probably would go for the ACB as ive heard nothing but good reviews for the dry.

Superb in the dry on a track but tramline dreadfully on a normal road even in the dry1st_petrolhead said:
My advise, stick to CR500s for the blats and buy a second set of rims and run slicks for the trackday. You can get part worn slicks for £25 each, much cheaper than killing your expensive road tyres on a track
Yep one of the best upgrades for a 7 is a second set of rims as they are so tyre sensitive rubystone said:

Personally, I think CR500s have no grip, and would go for Toyo R888s for pure road use.

I've seen that Citroen C5 advert - perfect roads, no camber...ACB10s would be fine on that. I use ACB10s on the Ring and the roads in the surrounding area and they're fine, even in the damp.

But the old A120 from Dunmow to Braintree, all that damage caused by countless HGVs....they are truly dreadful...and let's face it, that's what most of the roads are like in the UK! My HPC hunted out every camber, rut and whiteline on the road and was truly unnerving. Changed over to CR500s and it was a pussycat!
I've run CR500s on all but 2 of my 7s and they are the best compromise tyre for everyday driving IMHO. OK, so on-track they can overheat, but for road use, they are great. Two caveats here -
1)I've not tried 888s!!!!! A friend has just fitted them to his car and I await a runing report :-)
2) Would a CR500 offer as much grip as a 32/48 or 888 on a hot day? Probably not (but it is all relative)...but on a cold day...I think I'd rather be running CR500s...

that's why you've got an LSD fitted! 
Anyway, who'd take advice from a bloke who runs round the 'Ring with "Big Bird" in his passenger seat?
CR500 for mixed driving in varied conditions.
48s for pure track use and monitor the pressures
Steer clear of slicks unless you really knows how to drive on them.
Superlight / CSR used slicks will be past there best and you really have to be a good driver to extract the best from them!
ACB10's I tend to try and steer clear of personally.
On my race R400 I use CR500s / Superlight Wets / Yoko A048s

For track and the R888 i was using 22 hot last season, i have been using 20 this season on. Start with 18 for 22 or 16 for 20 all round get them hot and adjust them to 22/20 all round, when cold youll have something like: RR=17/15 RL=16/14 FR=18/16 FL=19/17. These were done when the track was cold but my mate got nearly the same results two years ago using Kumho V70 on a dry warm track.
I doubt the above will be two far out for Yoko's. I did have Yokos on my bike engined fury(ex tyre controlled RGB car) and swapped them for the Toyos and there was a big difference in grip.
I think the Toyo probably is the better tyre from my own experience and i wouldnt be put off by the brand or the price, they are definatly competitive, a set from c and s tyres in middlesborough is about 240 quid, dont know the price of the yokos. Im sure the Yokos are a good tyre having said that.
In the wet they seem to be good as well only being 6 secs slower in the rain.

B & W, what colour is your R500?...Who did it belong to before?
I'd not run ACB10s on an R500. But then I'd only run CR500s on mine. I don't push it hard enough on the road to worry about the difference in grip between a CR500 and a 48 - what I can say is that on track it's excellent on slicks...but also that ACB10s are great track tyres too.

Its yellow, not sure the number. Bought it off a guy called Graham, just north of LondonI'd not run ACB10s on an R500. But then I'd only run CR500s on mine.
