scooter Posted March 6, 2007 Share Posted March 6, 2007 Evening! I've decided to give ACB10's a shot on my BEC. I spoke with a local racer who told me that i should go with 215's all round... is this not a tad excessive? Link to comment Share on other sites More sharing options...
rgrigsby Posted March 6, 2007 Share Posted March 6, 2007 What BEC? ACB10's aren't measured like that anyway! I know some blackbird engined guys run 6*13-21 ACB10's and they seem fine. Are you really sure you want to do this? ACB10's have very stiff sidewalls and take a fair bit of getting used to on the road. They tend to tramline a lot and will reduce the ride quality a fair bit. I'd be more tempted by 48r's if you want that much grip. Cheers Link to comment Share on other sites More sharing options...
EvoDunc Posted March 6, 2007 Share Posted March 6, 2007 Richard Meadens Blade which has 6 1/2 by 13 rims all round is using 195,45,13 ACB10's and the big power K-series engined cars use the same on the front and 245,45,13 on the rear fitted to either 8 or 81/2 inch rims.

scooter Posted March 6, 2007 Author Share Posted March 6, 2007 You're right - they're not generally measured like that, but you will find the alternative measurement (in this case 215) on the tyre wall. I just thought it would be easier for everyone to relate to if I used 'normal' measurements. My BEC is a R1 engined Caterham... Link to comment Share on other sites More sharing options...
oldbutnotslow Posted March 6, 2007 Share Posted March 6, 2007 I had a flirt with 10's Oh my Gaud! with my suspension set up the car became almost undrivable on the road Country lanes at anything over 40mph were a nightmare. It seemed as if every bump has me heading for the ditch on wither side of the road depending on if the bump was on the near sid or the off side. I spoke at length to Avon about them and in the end they said that you would get almost as much grip from a set of Cr500's as the 10's. The chap did say that technology had moved on from when 10's were in the hey day. As you will know only too well 10's are Xply and the suspension will need to be set up with perhaps 1/2 degree neg at most on the front and 1/4 degree ears on the rear if its a Dedion. Trying to run a mix of Xplies and radials just doesnt work.

rgrigsby Posted March 6, 2007 Share Posted March 6, 2007 I'd stick with CR500's or 48's tbh, the only big advantage ACB10's have is that they are very light compared with most other tyres. Link to comment Share on other sites More sharing options...
Gridgway Posted March 6, 2007 Share Posted March 6, 2007 ACB10's work brilliantly on my supersport on road or track. Luv em. Graham Link to comment Share on other sites More sharing options...
shn7 Posted March 7, 2007 Share Posted March 7, 2007 I'm with Gridgway on this. Only wish they came at the same price as the Yoko's. I don't really believe the in the end they said that you would get almost as much grip from a set of Cr500's as the 10's. I run CR500's most of the time but when I swithc to ACB10's the grip levels increase considerably (in the dry) especially once they are warmed up. Steve.

lsb Posted March 7, 2007 Share Posted March 7, 2007 Acb 10's are a fantastic dry weather track tyre, they do what they are supposed to do. They will get you to and from the track but they will never be a fantastic road tyre. I do not not believe you will get more dry weather grip on track this side of a slick.

rgrigsby Posted March 7, 2007 Share Posted March 7, 2007 I wouldn't disagree about the grip comments, there's no way a CR500 is as sticky as an ACB10 but I'd still prefer a CR500 on the road. 😬 Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Gridgway Posted March 7, 2007 Share Posted March 7, 2007 I was perfectly happy with my ACB10's on the road. Currently on CR500s as they are my wet wether tyres. I polished my ACB10s and am too tight to buy some more at the moment! Graham Link to comment Share on other sites More sharing options...
MikeE Posted March 7, 2007 Share Posted March 7, 2007 and the other big advantage (IMHO) with ACB10s is they are very predictable/progressive on the limit which make 100mph oversteer far easier to perfect - they're not bad on track either 😬 R400 Duratec Build and Modification Pictures here Link to comment Share on other sites More sharing options...
robmar Posted March 7, 2007 Share Posted March 7, 2007 personally I am gutted that I will no longer be running ACB's on road or track 😔 once you get used to them they are great, and as it don't do too many road miles running the softest compound was not a problem FWIW I ran my superlight on 7* 21 (front) and 7*22 (rear) no problem rob Link to comment Share on other sites More sharing options...
dannylt Posted March 7, 2007 Share Posted March 7, 2007 ACB10's also work amazingly well in the wet, if you can keep them up to temperature and avoid standing water. I'll be switching to CR500 "wets" a lot let this year for sure! They also have the advantage of working pretty consistently down to the canvas, but they very quickly go bang after that! Would never drive far on the road with them though... Link to comment Share on other sites More sharing options...
Jason Plato Posted March 7, 2007 Share Posted March 7, 2007 100mph oversteer far easier to perfect - they're not bad on track either 😬 I like ACB's, but only if the camber and toes is set correctly, otherwse they can be a nitemare! ps 48R's tramline almost as much when worn here is C7 TOP Taffia Area Rep Link to comment Share on other sites More sharing options...
Gridgway Posted March 7, 2007 Share Posted March 7, 2007 Do ACB10's still get used in racing anywhere? It was good when they were used in caterham racing as you could get 2nd hand ones easily. Graham Link to comment Share on other sites More sharing options...
Paul McKenzie Posted March 7, 2007 Share Posted March 7, 2007 Graham, Still used on FF's...so available cheap.....but also a nightmare on the road, IMHO , although fab on track. I've just changed to 048's and the immediate result of much lighter steering and massively reduced tramlining makes me glad I did Paul Link to comment Share on other sites More sharing options...
Gridgway Posted March 7, 2007 Share Posted March 7, 2007 Paul, do you have any tips on where to go to find FF racers getting rid of them? Graham Link to comment Share on other sites More sharing options...
martin b Posted March 7, 2007 Share Posted March 7, 2007 Graham I have 2x 7/21 and 2x 8/22 in my garage if your interested, less than 1/2 worn and i'm only near Redhill, been meaning to sell them for a while, not sure how much they are worth though.

lsb Posted March 8, 2007 Share Posted March 8, 2007 Martin, How old are the tyres ? If they are reasonably new I would be interested. Also live in Surrey so can collect, please let me know how much you are looking for via blatmail, thanks. Link to comment Share on other sites More sharing options...
Gridgway Posted March 8, 2007 Share Posted March 8, 2007 Thanks Martin, but they are a bit big for my poor old supersport. Graham Link to comment Share on other sites More sharing options...
