1400rs_0of30 Posted March 28, 2002 Share Posted March 28, 2002 I have new ACB10s on this week for the first time ever, normally go for 032Rs. I haven't been on track with them yet, but am concerned with how slippy they are even round roundabouts. I have the soft a24 compound acb10s, expected them to be like superglue?? Am i just being paranoid ? do they take a while to grip..only done about 10 miles on them so far, or not hot enough to start to grip? Experiences appreciated..

EFA Posted March 28, 2002 Share Posted March 28, 2002 Takes a while for the release agent to wear off - say 100 miles. They are also not great until they warm up. Then they are phenomenal for something street legal!

R500 CYA Posted March 29, 2002 Share Posted March 29, 2002 Don't worry Sean they do feel terrible initially, and like all race tyres they really need heat and commitment to make them work properly, the harder you push the better they work. I'm taking ACB's and 32's to Goodwood on Saturday, so if you want to do a back to back comparison you're very welcome to use my set for a few laps, but you wont be disappointed with the advantage of the Avons I assure you!

Peter Carmichael Posted March 29, 2002 Share Posted March 29, 2002 What tyre pressures are you running? Should be about 17psi cold all round. A24 is a brave compound choice - mind that you don't overheat them on track. Link to comment Share on other sites More sharing options...
kenny. Posted March 29, 2002 Share Posted March 29, 2002 As a non List 1A novice, how do CR 500's stack up in comparison to the 2 mentioned tyres, as I'll be running on them shortly. Cheers, Kenny Link to comment Share on other sites More sharing options...
Paul Ranson Posted March 29, 2002 Share Posted March 29, 2002 ACB10's are crossply. So you will find that they run bigger slip angles than radials without letting go, and that they don't let go so abruptly. This can feel a little odd. Heat is also good. And getting the suspension angles vaguely right. Paul Link to comment Share on other sites More sharing options...
Darryl S. Posted March 30, 2002 Share Posted March 30, 2002 Interesting comment Peter regarding overheating A24 compound ACB10's on the track. We're using them for sprints/road tyres and having loads of success with them. Seems you can just go out and get into it whereas with the A032R's the first lap was more used for getting tyres up to temp. Wear isn't nice though and yes they do seem to go off ever so slightly if its a really hot day. Have you a recommendation on compound?

Peter Carmichael Posted March 30, 2002 Share Posted March 30, 2002 On the bigger 7 inch and 8 inch ACB10 sizes, the A30/A31 compound seems to be a good choice. It is the medium compound. Link to comment Share on other sites More sharing options...
Darryl S. Posted March 31, 2002 Share Posted March 31, 2002 Which are the sizes we're using Peter, have you done any testing comparing A24 compound to the A30/A31 with regards to wear/lap times? Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted March 31, 2002 Share Posted March 31, 2002 CR500's are good but not in the same league as ACB10's. Agree with Paul about the slip angles. It does feel a little odd when you go straight from radials to crossplys. Alex Link to comment Share on other sites More sharing options...
Red SLR Posted March 31, 2002 Share Posted March 31, 2002 I love ACBs, they just feel brilliant, esp when up to temp. But at 100 a go they are expensive so I keep them for when I go on trackdays and run A032rs on the road, and A501s on hill climbs which are complete cr@p! Simon.

murph7355 Posted March 31, 2002 Share Posted March 31, 2002 Why not use slicks for trackdays? 15 quid or so a go for scrubbed in ones and better still than ACB's. I know a man that makes nifty wheel racks for transporting them to the circuit... Link to comment Share on other sites More sharing options...
Swiss_Tony Posted March 31, 2002 Share Posted March 31, 2002 Andy Where do you get these slicks from? What sort of sizes are available? James Link to comment Share on other sites More sharing options...
