    machining wheel centres

    Anyone got a rough price how much it costs to bore out the centre of a set of 4 wheels? Also what size do they need to be bored out too to fit gtt hubs?

    I got quoted about £20 a wheel by countless machine shops.. Then this one shop said ... oo your looking about... mmmmmm... £7.50 per wheel... needless to say they got the work.

    £20 a wheel, everyone wants to be a millionaire these days. £7.50 a pop sounds fair.

    Cheers guys 7.50 ain't bad, going to start looking for local machine shops. Can anyone double confirm that its 60.1? Does sound about right to me.

    60.1 mm is what the GTT hub is

    Re: machining wheel centres

    I paid £20 each, they had to lathe through from the back about 40mm deep and leave the lip on the front so the centre caps still fit.

    There's no way I would be able to do it myself, at least I know its done properly.

    I had them done to 60.2 just to be on the safe side

    ET35 is standard size matey, 60.1mm bore, 4x 100PCD, I used to run ET37 but had to run 3mm spacers on front so tyres could clear coilovers

    Offer cash, they might drop the price. There's always someone who'll do it in a lunch break for beer tokens

    Re: machining wheel centres

    That should be ok then i guess and itl give it a bit of a wider stance. They are still only 7j, would prefer 7.5 or 8j as there only going to be for track so doubt il need to get to full lock, but there cheap

    7J on 15s should be all good for trackdays, ideal for 888 tyres. I guess having ET25 gives you a wider track
