Wheel Spacers Versus Performance

Is there still enough hub left sticking out for the front wheel to catch on, since its a fairly thin spacer????
H&R is way more expensive but advertises hub centric on both 7mm and 15mm.

The FVD 7 mm spacers are definitely hubcentric, I have them on my vehicle. Perhaps, their site doesn't have a good photo of them, but they are definitely hubcentric. To answer your question, any spacer thicker than 5 mm has to be hubcentric.

I am doing 15s on the front and 20s on the back..........with 18" sport classics. Why 7s and 15s do you have a different wheel or is there a negative with sizes higher?

The car feels much more stabil, especially over ruts. I have a feeling that there is a roll centre change as well.......towards the longitudinal c of g give less of a roll moment.....can anyone confirm this?

I have 18 carrera lights.

I've never heard of going 15 and 20. seems a bit much. I don't have much knowledge in this area.

Also will this help run a wider rear tire. Like going from 265 to 275 or 285??
