Hi guys hope someone can help,

I have a st170 and last year brought a second have spec stage 3 flywheel and clutch off of a good friend of mine, when fitted and wile cranking it would make a loud wining noise and sometimes not engage at all.

thinking it was the flywheel ..(witch in the end killed the starter)..I got in touch with spec and order a new clutch and flywheel set up brand new with a new starter and first turn of the key same noise, after removing the starter its clear to see the ring gear has been touching the centre of the starter dog pushing against it and not just the teeth

its a 03 reg and have heard they changed the flywheel surface area from 230mm to 240mm but cant really get a straight answer to weather the actual flywheel size is the same or not, I was never asked or had a option of size when buying it, and after contacting spec they say they've never had any problems in all the years selling them

that said there is a thread on here from a guy with the same problem but he hasn't been on in nearly a year lol

if anyone can shed some light on the hole flywheel sizes thing it would be much appreciated, the cars supercharged so a right bitch to get the starter out

many thanks lewis.

Hi I think there should be 135 teeth on the ring gear so if you can count this maybe a good place to start

thanks bud

ok finally got round to removing my flywheel and iv now found its to big lol its the right flywheel but 2mm to big as a diameter or 1mm each side as a radius

the ring gear that is sorry guys, spec arent very helpful they just say theyve never had this problem before, iv got the part number for a svt starter so just need to see if the starter gears are the same size
