as the header says < will the 300mm discs and calipers of the st220 fit under the standard propellor wheels ?

Its a y reg 1.7 ,so I think its got 260mm disc as standard

any help chaps ! thanks
 
In short: no.

For ST150 brake setup (280 mm discs) you need 3 mm spacers for propellor wheels to clear the bigger calipers and that is the biggest brake setup that fits inside 15" wheel without grinding. For 300 mm brakes you need at least 16" rims

Ps: I wouldn't want to be rude, but there are plenty of threads about brake upgrades on puma and all are easily findable using the search function which is working very nicely... That would answer all of your questions, even those that had not occured to you yet...
 
Alternatively 300mm brakes do fit under 9 spikes with calliper grinding, no need for spacers though.
