Just got a set of 14's for track work and 15's for road use. Im looking at rubber for them but all the top tyre's im familiar with are not available in these smaller sizes.
I find myself heading down twisty country roads quite frequently so im looking for performance rubber. Can you guys recomend some suitable tyre's?
Currently looking at Toyo T1R's for 15's and Yoko A539's for the 14's.

Another vote here for the Toyo T1-Rs, excellent on the road, good for shorter sessions on the track (overheated after 4 laps of the 'Ring)
As for track tyres, maybe these?

Camskill's have good prices on the road tyres, too.
Edited for wrong size tyre

Might go for the R888's ultimately. My mate recons putting 14" wheels on will bugger the handling so I was possibly thinking of just using the 14's I have for looning around. Thing is, I swear my car came with 14's anyway so I don't see hwo fitting the same size tyre will bugger the handling.

Keep the rolling radius the same and geometry won't be affected. I did notice a difference going from 14" BBS > 15" BBS on mine, mainly because the lower profile tyre flexed less on the sidewall. The overall size of the wheel+tyre stayed about the same (about 23.5" diameter). This changed when I fitted 50-profile tyres later on, tightening up the car even more, but losing just under an inch of tyre+wheel diameter (the speedo now reads another 3% over).
The only worry I would have using 14" wheels on the track would be the possibility of rolling the 60-profile tyres off the rims. They look awfully tall to me.
But I expect Toyo know what they're doing

as steviec says, the Kumho Ecstas are a good choice and i've used them quite often. although i've just changed to a Goodyear Eagle F1 setup on the front and Kingstar K106's on the rear, and CANNOT fault these tyres! amazing, wet and dry! the tread pattern is brilliant and really does work. and they have quite a good wear life too

Because as was rightly said, they will flex alot more due to the taller sidewall, and also they are 14" bottletops, not BBS's, so will probably weigh more than your Alpina reps!

iS may have come with BBS's, but he's just bought a set of bottlecaps!
I thought bottlecaps were steel? Are the reps really heavy or what?

I have shopped about for tyres and honestly found a site that can deal any size and most makes including toyos its
www.mytyres.co.uk deliver straight top your door then find a fitter that will do them, I use National as a back hander ten quid a tyre fitted and balanced, a rough idea local tyre shop to sell and fit toyo t1r is over £80 for 205/50/15 from the web same tyre £43 and tenner fitting saved £27 quid time that four times...... Cheaper over the internet.

I don't think bottletops are steel, mine seem to do the flaky thing just like normal alloys!

Standard wheels were steels with iS specific hub caps, alloys were an optional extra.
