Not sure where to post this, but I'm trying to generate some interest here. I'm trying to set up an opportunity for us 4x108 guys to get these wheels in 17x8 with a +45mm offset. If you're interested shoot me an email with:

I'm keeping a tally of how many people are interested. The company I'm working with will chime in when everything is set up.

Thanks!

how about a 17x7 +45 mm offset so we can run them in SCCA Solo Street formerly known as Stock category.

It all depends on demand. It depends on what is most popular between everyone that would be interested. I believe 17x8 would be the more popular choice, but I've been wrong before. Shoot me an email if you're interested.

Tim, going with a 1" wider rim, shouldnt you go down 12mm on the offset - otherwise you are adding 1" to the back of the wheel with the same offset.

 

[Tim McCarthy]

There's also a +35mm offset which is an option with that wheel.

I suggest a 35mm offset over a 45 with a 8" wheel. Our fenders have next to no inner lip.

 

[Tim McCarthy]

Honestly I'd prefer a 35mm offset. Just unsure of what kind of stance people like with these.

Offset is measured from the center of the wheel and 47.5 mm is stock.

If you got a 17*8 with 47.5 mm offset it would grow 1/2" in on the inside and 1/2" out on the outside with no change in scrub radius.

A 17*8 with 35 mm offset would grow 1" on the outside and 0" on the inside with +1/2" added to the scrub radius.

Any way, before you buy wheels understand the specs, why you don't want too much scrub radius and how they will fit.

I say stay as close to 47.5 mm offset with a wheel that will fit and you will be happy.

We picked up nearly a full sec at Road ATL by adding 20mm of track width, each side on the narrow Fiesta chassis. Thats a bit much for the street but 10mm p/side would add some stability.

So with that offset what size tire are you thinking will fit ?? Should I keep my 225/45/17 Dunlaps ?

We are working to get a group buy going for the Fiesta ST RPF1 Wheels.

The choices I was thinking
1. 17x7 +45mm (Closest to stock)
2. 17x8 +45mm (More width more Grip !!)
3. 17x7.5 +48mm (A little wider but the offset is tucked more then stock)
4. 17x8 +35mm (Stance, fender work is more likley, more stress on the wheel hubs)

Please help Tim and us so we can get these wheels made before spring.

At OAKOS we don't have a Fiesta to measure a safe wheel. Based on my knowledge of wheels I think the 17x8 +45mm would be the best choice but is 1/2" closer the the strut going to rub? 1/2" to the fender going to rub? We need some help to get this information so all input is welcome, and needed.

Thanks everyone!

Bump!

I was going to do a wheel clearance measurement anyway just for myself. I will try to get that knocked out this weekend. Is there anything in particular you want to spec out? This will just be static in my garage, so all dims will be with no suspension compression other than the weight of the car.

Btw, I love the rpf1, but I would rather see a 16x8 size.

 

[AlrightyThen]

I think it would be sweet if we could get these in the same rado grey finish that is optional from the factory on stockers...

The color options that will be available are gunmetal(similar to rado grey) or bronze.

Since I don't a FiST yet, can you measure the distance between the outside of the wheel hub(where the wheel gets mounted) to the shock? Trying to make sure a 45mm offset will work on an 8" wheel.

As Eric said, for those of us who will be running our cars in SCCA events, our choices are limited by rules. It appears that a lightweight 16x7 would be optimal for the stock classes (17x7 for those who want to keep the stock size), and 16x8 or 17x8 for Street Touring.

I was thinking 16x7.5 would be excellent.

Sorry for the delay, I finally got a chance to lift the car and check out the clearance for the wheels. There is a pretty generous amount of room in the wheel wells. To be honest, the biggest issue is the amount of clearance between the tire and the strut. With the stock wheel and tire, there is about 18mm of clearance between the tire and the strut assembly. If you are only looking at an 8" wheel, outside of a crazy low offset, you should be fine.

 

[wash]

I need to look myself but that 18mm, is it strut to rim or the actual tire sidewall?

It does sound like a 17*8 et 48 would fit with about 1/4" to the strut and 1" wider track width (measured at the rim).

With a 16" and the strut angled out toward the hub, an et 45 or et 42 might be needed to clear the strut and that will increase track more.

Coilover shocks could change the clearance too.

Lastly, not all rims have the same dimensions so different wheels will have different clearance, an rpf1 in 17*7 et 47.5 might not have the same 18mm clearance as a stock rim.
