wheels and tire all 4 same size for track????

No, less number means more room for brakes. Less number means the mounting surface of the wheel to the hub is closer to the exact center of the wheel if looking at it from top to bottom. Less number also means the wheel will weigh more because the spokes are longer since they have to have more metal to reach the mounting surface further in to the wheel. A rpf1 +45 or +38 won't fit because it hits the caliper. But going lower extends the spokes out further and gets the inside of the wheel off the caliper.

I'd go with whatever makes you happy. However what I'd do and what I did when fitting wheels was buy a few spacers front and rear and see what fit best and what I liked best. If my rpf1 +45 fits with a 20mm spacer (so +25 overall), I'm sure the +27 will fit without issue and will look very nice without having to worry about the fender being lowered on swifts. However still buying a 5mm spacer wouldn't hurt and you can return what you don't use as long as you don't bolt it down and scratch the finish. Just pop the spacer on the stud and hold the wheel against it and see if it hits the caliper.

We all have that problem with enkie and our brakes!! But with spacer help we'll find a way!
