Fiesta project car: weights and bolt patterns

Our Fiesta got some scale time, and we measured the wheel bolt pattern too. Surprise: It's not the same as the Mazda2.

I own too many 4x100 wheels to consider a Fiesta now.

I have a set of Focus wagon wheels (the light factory 15 inchers) that you can have if you want them and I could figure out how to get 800 miles east. Might be good for something. Better than sitting in my garage anyway.
Bolt pattern almost had me in a fiesta instead of a 2 simply because I have these wheels.

Could the hubs be swapped? Too expensive?

Disregard i forgot they sell the new feista here now.... Post was for old kent powerd E36 M3 boxes...

Besides expense, almost certainly not class-legal.

There are some 4x108 wheels available---Rota makes several different wheel styles, for example. We're going to start with a Rota RB 15x7, as it is over the B-Spec weight minimum of 13lbs at 13.8.

Would a set of 13s clear the brakes? You could put on a set of Ford Tempo steelies!

interesting- based on all of the interenet hype, I expected the difference between the 2 and Fiesta to be a lot more than 140lb. That is not a whole lot.

(and I'm pretty facinated by b-spec, the more I think about it, the more reasonable way to go racing it seems)

Well, its a base Fiesta, not a loaded up one. I imagine that adds some weight.

I like the power delivery of the Fiesta a lot better than the Mazda2.....

So its going auto-x, not rally?

Their Mazda2 was also a touring which has the fog lights and the rear wing and some other stuff. Maybe they're actually closer than the 200 lbs that's commonly advertised though.

You need 4x108 wheels in a FWD offset? Check out the earliest (93-4?) Volvo 850.

108 yes, but I've never seen a 850 with a 4-lug pattern.

I am loving this project. I have a 2011 Fiesta SE hatch and think it would be a great B-spec racer. The weights surprise me, however, as I was expecting it to be a bit more. I am thinking of building mine into a DD/STF autocrosser, and this may push me over the edge.

Looking up all of the options, I'm not so sure how much weight that would be.

Heated and leather seats- may add some wieght, but not all that much. 16" wheels- kind of a wash Glass moon roof- this seems like the one that weighs something significant. Maybe the 60lb that is the miata premium for a power hard top, but I can't see it that much.

The different sync/ radio packages- I can't see that changing the weight all that much- maybe one lb, but it's not going to be like a iPad to 17" notebook kind of weight difference- they all have some kind of display.

If there's a fully loaded Fiesta, maybe 60lb more. But that seems very much like a stretch. And even that isn't all that much. Especially when you consider that the extra 10% weight (being conservative) gets 20% more power (120 vs 100) 14% more torque (112 vs. 98). I suspect that will be a lot closer when full B-Spec is put on.

Anyway, with all of the i-net hype, I expected a WHOLE lot more than 140 or even 200lb.

The very early ones were, switched to 5x108 in 95 or late 94 I believe.

Focus wheels 00-11 were 4 on 108 and available in 14 inch steel, 15,16,17 aluminum wheels. The aftermarket has been selling wheels for the Focus since 2000. There are plenty out there used and new, just not as common as the 4 on 100.

Is the offset all wrong for older mustang/pinto/capri wheels to work? Pre-mazda escorts should be a match. Wasn't there an earily 924 or 944 with 4x108?

I don't want to dig up a very old thread, nor do I want to start one for a simple question...

Is the hatch back Fiesta required for B-Spec racing? When I look at the rules, both SCCA and GranAm have the "4 door Fiesta" listed, and I've only seen the hatch 5-door cars being prepared and run for B-Spec.

The reason I ask is total cost to go pro-racing. There's a salvage 4 door manual Fiesta on e-bay, which appears to have been hit in the drivers front. Seems like a perfect platform to base a race car from. Say it sells for $5000 w/ Salvage Title- $2500 for the B-Spec kit, and call it $2500 for a cage, and you have a "spec" racer for $10k. Seems pretty reasonable.

Contour wheels work great.

Yes, really. The earliest n/a 850 had 4 lugs.
