I bought some Diasec warmers last year for £130-thoroughly recommend them. I also rode the TZ last year without warmers-on slicks-at Donnington and lasted 1.5 laps of the warm up before losing the front at Coppice. The tyres felt bloody horrible whereas normally with warmers you can just go straight out and hammer it. 2 points, yes you do need a genny for lots of tracks-Cadwell, Mallory, Oulton. The warmers take 1.4 kilowatts of power so most 'suitcase' genny's are not powerful enough-I am getting a 2.2 Kw Honda for this seasons racing. Even if you go to tracks with power get one of the blue plugs, they are about £4.00-at least that way with an extension lead and 13amp and blue industrial plugs you will be prepared for all eventualities.
