Wheel Spacers Versus Performance

Do wheel spacers negatively affect performance in any way?

wouldn't the cars +/- Camber/Caster and +/- Toe In/Out remained unchanged?

I don't want to increase the rotational mass, so I assume the billet aircraft aluminum are relatively lightweight spacers.

Who makes quaility spacers? I was looking at Eibach. (hub centric)

anyone?

Thanks

Assuming that all things are correct with regard to your alignment specs, adding spacers should have little or no impact on your current suspension set-up. FVD probably spikes a bad chord with you, however, for one price their spacers kits come complete with everything that you need ( i.e. correct length lug bolts, countersink screws ect..), and quality is excellent. In fact, I believe that they actually sources theirs from H&R.

I have no problem with the company if they supply a good product. Just looking quickly at the spacers they sell. They have the best price I could find, but there 7mm spacers are not hub centric like there 15mm. 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??

To answer your question, yes, enough left though just a bit.

BTW, my wheels/tires are the stock 17"

Took another drive today, all is good and the handling def improved!

Looks good. not quite enough spaceage for me though. 23 rear 15 front will bring the tires completely flush with the fenders. Yours may handle better though. mine feels like the front is a little slower when turning. anyways mine will be for sale as soon as I can get pics up. Returning car to stock and selling it.
