They used to be badged 'Formula R's but were actually called Dj98's, however I think the very latest ones are D01J's or similar.
They are tought to get from the local tyre place, they usually have to get them from the Dunlop Motorsport factory.
I tried to get a set of Dj98's when they were new, proved virtually impossible at a reasonable price, so went for Colway intermediates (similar sort of thing but much cheaper). 5000miles if you are lucky
cheers hope fully blade will leave some details .
If they are around the same cost of So2 s than I will try them 'fi not might as well stick to the wet handling of the So2s,and forego the track aspect .
will have a search around the web sites.
D001J - direct from dunlop, or via south shore tyres - about £120 for my size (235/40 -18) as I recall. Awesome, really hard wearing - BUT - you have to get alot of heat into them or you don't have much grip. Once hot, #### me, do they grip!
