Technical Stilo Blade Alloys

My Stilo Abarth has its original 'blade' alloys which are:
Speedline 7Jx17" 10-spoke, 4 stud, 98mm pcd, offest ET37mm, centre bore 58.1mm.

Is that the info you wanted...?

These ones ?

i have those(post in pic 3 are blades, other pic no idea of name but that offset not listed in stilo manual ) looks like 7j17h2-41 on the back of the spoke
looking in my manual shows std alloy wheels should be all 7j wheels 16" and 17" are et 41
then 6 1/2 j x15 et 43
the std tyres for those blades should be 215/45r17 87w or 215/45zr17 87w
although im sure i ran with a 87w 91w or 91y rated tyre

Thanks, with them being ET41 means i'd have to run 205/45r17 88w on my Fiat Idea to keep the correct wheel settings.

Don't get hung up too much on the precise dimensions.

The difference between ET41 and ET43 is just 2mm difference per wheel (or if you prefer, just 4mm difference to the track of the car). I don't think you'll notice it.. :D

Keep the original tyre size (215/45x17) since changing the size to a 205/45x17 will affect the gearing .. and actually does not affect the track of the car. A 205/45 is narrower but is also a smaller height than a 215/45... so you would be reducing the circumference of the wheel/tyre.
