My reasoning behind this is for a better contact patch ,and a better grip than the 185's the car currently has. As far as roadholding abilities should i go with the 16's (205 45 r16), or 15"s and a 195/50/15?
would these 2 sizes offer about the same grip, assuming were talking the same brand of tire.?
Only getting a chance to reply now.
Had a look at you
1.4 Black car and it looks very nice. Reminds me on the first 500 Sport with I had with the 16inch 5o-spokes which I was very fond of. IMHO it suited they suited the Black best in the 1.4 but they are more difficult to refurbish. The ones with the price tag were in Halfords (Euros).
To answer your question I would not go for the widths you are thinking off. If you are going to increase your footprint to 195 you might as well for 16 inch. If you opt for 205 then go for 17inch. 195 should be plenty. If you
have to have the ride comfort
and the footprint then the 195/50/15 on your Sport wheels would work well but you
may be limited on the choice in performance tyres in that size.

On the wheels you posted I would like to change my opinion and agree with the previous posters and they are were nice.:worship: I did a close up on them and with the angular style they're different.
Going back to wheel size that would be recommended in this if you opt for
7J - it would appear that
E30 would be the correct offset.

In your opening post you state that you have the Eibach pros and and Koni adjustables and the
ride is firm. In the LAD Motorsport F500 they
kept the 15 inch wheels for ride comfort. Article in this thread...

The recommendation from the previous poster IainG GPS to stick with 16s is probably a good one given his experience of the 17s & the 16s.
I found that with the 16s on the 2 previous 500s would hold the grip with the 1.4 nicely &
particularly on the Conti 2s which I really likes. They were in the standard size of
16 x 195/45 with a rim of width of 6.5J and E35.
Given your Abarth aspirations I would be tempted to go for
'light' 17s despite the insurance 'headache' and the more expensive tyres. TMC Motorsport may still be doing a 'special price' of under a grand 'all in' using excellent summer mid range Yohos and the Prorace rim - picture is of one in black but they would have them in a 'titanium' look as well. Tyres size on this would be 17 x 205/40. Recommended offset is E30 on the 7J rim. This would have probably worked if you did
not have the lowered suspension and had possibly opted for the 'standard' Sport springs and the Koni FSDs.
If you heart is set on those momos wheels don't let me stop you.
EDIT: You might have a problem with bore size in the 4x100 PCD....
