So I can't seem to find this info anywhere and thought it would be a great discussion.

Stock Wheels:
17"
Offset: ????? Does anyone know?
Rim Width" ??????

Stock Tires: Bridgestone Potenza S001 205/45R17

Obviously the offset / rim width determines what tires you can run on stock or otherwise. I would love to run 215/45R17, but have no idea if they will fit the stock Abarth wheels.

This is from Good-Win Racing:

Mazda designed the chassis under the Fiat 124 for LIGHT weight wheels like we offer here. Lighter wheels equal best handling and best ride quality. Stock tire sizes are 195/50/16 on 16x6.5 and 205/45/17 on 17x7... which means the stock tire diameters range from 23.6 to 24.3 inch. Within that range there are interesting upgrade sizes to consider. TPMS operates off ABS system with the ND, that means NO sensors in the wheels to worry about when changing to another wheel.

16" Wheels

195/50/16 tire size fits within the fenders on wheels down to about 35mm offset. For customers seeking more performance in 16 inch sizes consider 205/50/16 up through 225/45 on 16x7 and 16x8 wheels with higher offset. See product description for 16x8 Enkei RPF1 for pictures of this popular choice on our own Fiat 124.

17" Wheels

With stock size 205/45/17 tires you can run offsets as low as 40mm and still fit in factory fenders with 1 degree negative camber or better, we have run 38mm with more camber. An easy upgrade in 17 inch is 215/45/17 and that fits with our wheel choices that are 42mm to 50mm offsets.

MAX TIRE SIZE that will fit in stock fenders without a fender roll is 235/40/17 using our Advanti Racing, Konig HyperGram, and 6UL Racing Wheels in either 17x8 or 17x9, as long as you have about 1.5 degrees of negative camber or more. If the car is lowered and/or raced, this size will typically rub the plastic fender liners inside the wheel well at full steering lock and/or over big bumps/dips in turns depending on amount of lowering and amount of negative camber (same story with taller 225/45/17). This is all even more true for 245/40/17, which can be used by SCCA STR competitors with a fender roll. Picture here is our own Fiat 124 with our 17x8 Tungsten 6UL wheels and 235/40 Toyo R1R tires, fits great, grips for days!

Please note that most 15 inch wheels do NOT clear the big brake calipers, even on cars without the Brembo upgrade, and the effective offset to make 15 inch clear the brakes will usually put the tire outside the fender lip (and the fender arch on ND is bigger than prior Miatas, doesn't look right with 15 inch anyway). Thus, we do NOT suggest 15 inch choices on the Fiat 124.

54.1mm hub bore.

Any idea on weight for stock Abarth wheels?

No! Something I'd really like to know.
When I changed wheels on my Golf R32 it shaved 4kg a corner, made a nice difference to the handling.
Maybe one of the Tuners (Madness) would know?

The only thing i didn't like about my Abarth is the wheels. My car is black:-too black, the black wheels also look heavy and clunky to me. Solution; tirerack, enkei pf01 silver-(to break up the black.), get them installed asap, save originals
for winter tires if I ever go that direction.

Stick to that factory 45mm offset for easy fitment of wider wheels/tires, that includes our Konig HyperGram, 6UL, etc. If not going wider, you can also push the wheels out further with a more aggressive offset, I have raced the car with our 16x8 Enkei 38mm offset wheels and loved the effect of the wider stance.



Our experience with this chassis with the Mazda label on it counsels that it is extremely important to stay light with the wheel choices, the Mazda chassis engineers will tell you that light wheels are an assumption in their suspension designs and few things mess up the fun handling faster than going heavy. Stock ND 17x7 over 17 pounds, try to stay to that 17 pound range or less is our advice. I have not yet weighed the 17x7 off the Abarth version, but I assume similar lightness.

Example, our Tungsten 6UL and 235/40/17. Note these 17x8 wheels just 14.8 pounds, a few pounds less than stock 17x7 despite extra inch of width.

Thanks Good-Win: I did buy the stock size 17x7,45mm, but if I ever want to upgrade I'll contact you. I am 68 yrs old in good shape except for my heart, and not interested in pushing me or my abarth to the limit, Auto cross competition is the most demanding competition I am interested in. SCCA in Buffalo area holds autocross competition at New Era field, home of the Buffalo Bills and I do want to do it.

So after researching I have found myself frustrated.

Really, the Brembo brakes are making this a really hard fit. Ideally I would not have ordered them, but the car I wanted has them. Ideally I would have gone with a Wilwood Good-Win Racing set up front and rear. Seems a shame to pull the Brembo brakes off and deal with selling them.

Ideal setup:

17 x 8 Wheels with 45-38 offset
235/40/17
Fits Brembo
Light Weight (sub 16 lbs)
Black

The best option seems to be the 6UL wheels. Though GWR does not sell the black option, but Flying Miata does. These are "okay" as far as design, don't love them.

Other options I am missing???

I like some of the OZ options, but no 8 inch.

Pretty sure you can get the 6ULs in that size (among others). I ran those wheels on my S2000 (17x9, 17x10) and they are great wheels.

Go to the GWR web site. They have a bunch of options there if that style doesn't grab you.

I read somewhere that the stock Abarth wheels are 25 pounds. The ones that PureAdrenaline got from TireRack are 14 pounds, $185 each.

The MX5 wheels look nice and they look light weight. And if people like the look of the MX5 door sills, they could even leave the Mazda logos on them. :)

So after more researching I think the Konig Ultraforms are pretty good looking. Hard to find info, Good Win Racing looks like they plan on carrying them. Available roughly end of Feb. Weight 16.4 lbs. from what I can find. Clears the Brembo brakes from what I can find out. The dark matte gray may work with an Abarth trim, if not I will have them satin black powder coated to match the vinyl heritage wrap.

Konig Ultraform 17x8, 4x100, +45mm - Matte Grey

Those look pretty cool. If you like those also consider TE37s. I think they should be available in correct offsets.

How about spacers for those of us that want to keep the stock Abarth wheels? Is 15mm the recommended size? I don't want to go too big. And are they hubcentric? Are there some that simply bolt on, with or without longer studs? I've used H&R on a past BMW and had no problems so maybe they make some for our application?

Those look great as well! 4x the price though.

There is a thread on this. Search for Greg's comments from EC about pros and cons, and the need to buy quality spacers. Eibach seems to be at the top of the list. Argument can be made either way.

I kind of wish these cars had a 5 on 4.5 lug pattern. I still have a set of 17x8 Volk CE28N's in the shop from my wife's old track car.
