Hi there, has anyone got the drawing or technical data sheet for the 330 prodrive discs to suit a classic ? would like to compare it to the later wrx disc that measures 326mm to see what the difference is as i plan to cnc a pair of new brackets up to suit the smaller disc if its possible and save the expense of buying either prodrive or godspeed brakes

Many Thanks

Stefan

 

I tried this but the offset is different on the 326mm.if I remember correctly,I couldn't get my wheel on due to the offset

 

oh right, am guessing you didnt take any measurements at all ? trying to find any decent technical data is near on impossible regarding this

 

apart from being 4mm larger, the Alcon disc uses a 28mm thickness and the STi is 30mm for starters.........

they also sit approx 10mm further inboard than the STi disc........

The STi 30mm thick disc won't fit inside of the calipers , the gap is too tight

 

thanks for the info so far, keep it coming have done a 3d model of basic disc without the vents and grooves, am tempted to see if i can get some material and cnc a couple of solid discs up

 

and that would be cheaper than the available alternatives......

 

well i cant be any worse, after all think the price of these discs is a little rich to say the least, plus i like a challenge and working at the uni means i can use there machines and get materials at cost price and my time, still be nice to have some more info tho like the grade of steel i would need ? maybe a cheeky request but hey

 

Good luck with that

 

indeed, but been a toolmaker now for 16yrs so think i can manage to do the donkey work

 

Any use ?
