16" or 18"

[Paulgooner]

Hi, I currently have 16" spiders, and I think the car looks better with the 18". Ignoring the the spacer issue with 18", what are the differences and or advantages to having the 18". Is it worth the expense of buying them.
Thanks

Been told by some guys who do track days that the original set up for the earlier Tuscan was 16in thus the probs when going to 18in then needing spacers to keep it on the tarmac so to speak having 16in wheels for track and 18in for daily driving, dont no on later cars as when searching forums there are different suspension mods possibly to eliminate the earlier probs encountered and ironed out.If not had brake upgrade they do look a little empty inside on front wheels with smaller discs in my view.

The offset on the 18" is wrong for the car, it was always designed for 16" but always looks better on 18". In order to get the 18" on , and not sticking out of the bodywork they had to change the offset to accomodate. This led to a heap of associated problems with the geometry, earlier cars with the bells and rotors are the worst effected. Matt at SP did a lot of research on it and came up with the 3mm spacers to compensate for the offset. It is always a compromise though and the car handles better on 16's.

From that, I might just hang to my 16s,but the 18s tend to fill the arch out and make the car look so much better. I may look at something away from the spiders. The SP12s look good. Just have to find a car with them on to see what they look like.
