Has anyone installed the Fiat / Mopar OEM 20mm wheel spacers on their 2017 124 Spider Abarth rear wheel hubs? While also leveraging the factory rear suspension on their 2017 Abarth 124 Spider?

Looking to push the wheels out closer to the rear wheel well fender line vs how it looks from the factory.

So, I have not tried the 20mm from Mopar; however, I did put on 20mm from another manufacture (Amazon) - not sure what you mean by "leveraging the factory suspension". I'm still at stock height.

These are the ones I put on

I can tell you the 20mm fit with no modifications to the lugs, wheel or hub

I can also tell you the 15mm will fit, but you will need to modify the lugs to get the stock Abarth wheel on.

I have always been a believer in not using wheel spacers. the redistribution of load tends to make wheel bearings wear quickly causing potentially unsafe situations

the loads are centered on the bearing a bit better when the rim is the only part of the equation. adding large spacers place stresses which tend to have the effect of adding outboard load to the bearing causing premature wear and failure.

Is there a difference between this and a new set of wheels that has a different offset?
Yes, some. What rdass623 said about the geometry change is true whether the change is because of the addition of a 10mm spacer or because you put on a wheel with 10mm less backspace. There is another difference to consider, though, which is that the spacers are NOT part of the wheel, but a different piece of hardware. You want to make sure to get spacer or adapters that are hub-centric on both sides, and not use "universal" pot cast junk that have poor flatness and don't have proper hub bore (and lip, depending on thickness).

I think Eibach and H&R both make spacers and adapters for the 124, but there are so many wheel selections, you're probably better off just finding a wheel you like that's a little wider.

Also, back to the original post, they mentioned REAR, as if they were only going to put spacers on the rear. Doing that is like putting wider tires on only the rear. What WAS balanced handling will turn into UNDERSTEER or PUSH, because the rear tires have more track and can take more cornering force than the front. That handling change can catch you off-guard and send you plowing into something you thought you were going to be able to steer around in an emergency. Whatever you do, you should do in a way that maintains handling balance.

Hi SVTour,

This is a great informative post. Can you please clarify for me in the photo of your car, is that with 20mm spacers on the rear and 15mm on the front, or is it 20mm spacers on both the front and rear?

Are you still happy with the spacers?

Thanks,

Ryan

hi Ryan - sorry for the slow response.

The pictures above show with the 20mm spacers all around. So far, been happy with them, no issues or concerns have come up since placing these on, and no paint issues with the wheels being placed further out (rocks hitting paint). I still like the look of the wheels being pushed out...

Regards,
Joe

H&R spacers, 15mm all round. Historic Alloys have a wider rim at front face which I like, and clears Brembos
