5x114.3 swap

[macuser27]

Greetings.

For those of you that did the 5x114.3 swap, what vehicle(s) do you enter/search when looking for wheels online?


Thanks!

What is your reason to go to 114.3? The only reason I could see is if you already had a super expensive or rare set of wheels in that pattern already.

Technically, 5x114.3 hub bearing is strong than 5x100 hub bearing(for Subaru).

5x114.3 have more wheel options than 5x100. Yes, sells of 86/BRZ brought more wheel options in 5x100, but compared to 5x114.3 we're far from the design and especially offset options. Example, I wanted Advan TC-4 17x9+35, but sadly they only make that in 5x114.3. Closest is 17x8+45 for 5x100. This goes not only for Advan wheels, but several other brands.

And to answer the OP, just look for the specs of the wheels more than searching for the car. At least that's easier to search imo.

I had considered the strength aspect, but that has seemed to only been an issue for those of us that regularly track our cars. I have been through 5 front hubs myself.

I knew that there where more wheel sizes available but given the OP didn't even know what cars use that pattern it made me question his motives.

Not only track peeps, but peeps that own aftermarket aggressive offset will wear out the hub bearing quicker... but tbh that can be said the same w any hub bearings.

Yeah, my wild guess is OP is thinking of doing the hub bearing swap and trying to figure out what wheels to go w afterward.

Is 5x130 possible? I need to show some Hondas who’s boss.

With enough time and money, anything is possible. Lets go 8X200mm and really show the Honda's who's boss.

Thanks for the quick replies. I should have added more info in the original post.

I've been doing track days for the past 5+ years and recently bought a 2013 BRZ built for the track (Stoptech BBK, welded-in roll bar, seats, harnesses, etc). I would like to upsize the current 17x7 Kosei K4R wheels (discontinued) to 17x9 so I can run 245 width instead of 215.

I have been researching wheels (size, weight, offset, etc.) for BRZ and noted they come 5x100 from the factory. Then realized that the current wheels have 5x114.3 cast on them.

FYI, Tire Rack does not allow searching for wheels without putting in a vehicle. America Tires allows putting in sizes to look at wheel but doesn't allow ordering without putting in a vehicle.

In case it matters, the car also has 10mm H&R spacers all around with aftermarket extended length studs as well.

Thanks again.

I had a set of Kosei K4R's , the 5X114 marking is a mistake. Here is an old picture of mine when I had them for sale and I am on stock hubs. I would check your hubs but I bet that is the case.

I'd hunt Apex race parts , Counterspace Garage, or 949 Racing for wheels. They should have some 17X9's to get you sorted out.

WHAT!

Off to measure the bolt pattern on the hubs. Thanks dude!

aren't the bearings the same size though? i understand the wheel mounting/mating surface is stronger, but for compatibility, the hub-to-vehicle mounting surface must remain the same, so there's not a ton of extra space for an improved bearing design.

It's true. I have two sets.

Bearings are the same size. Yes & no. iirc Subaru do use different bearings on 5x114.3.

Anyways, think if the wheel had no bolts and was glued on with some super duper glue. The forces to the hub and bearings would not change. What does change is the lateral forces near the center of the wheel itself. The closer to the center of the wheel the bolts are, the more lever arm the tire cornering forces can exert on the wheel between it's outer edge and the bolts. Everything within the bolt circle has essentially zero force. So the farther out the wheel is bolted to the hub, the less force is exerted to "bend" the wheel.

TLDR: 5x114.3/STI hub assembly is stronger. If you're tracking the car.

You could search by a 2008 Hyundai Tiburon V6 SE. Stock wheels are also 17x7" ET48 but with a 5x114.3 bolt pattern, they have 12" front brakes, and spacing to the front fender lip, etc. are pretty similar.

I only know this because my last car was an '06 Tiburon that was running a factory 12" brake upgrade, and the wheel specs I've been looking at for my BRZ are essentially identical to what I ran on that car except with the 5x100 bolt pattern. E.G. a 17x8" ET35 with 225/45's are what I ran on my Tiburon and that's a widely recommended fitment on the BRZ as well. Both require some negative camber in the front to not poke, etc., so very similar.

Some caveats: if you have the Performance Pack brakes, it won't account for clearance on those, and it seems the BRZ has more clearance on the inside (I.E. mounting face to strut/spring) than the Tiburon, so you'll be limiting choices a little with that as well. Actually, there's likely a little more clearance all around on the BRZ, because I don't know of anyone in the Tiburon community that was able to run 245/40-17's without rubbing unless they rolled fenders, etc.

That said, there are a BUNCH of good wheel fitments in 5x100. I was in the same boat, looking at doing the conversion because I was annoyed I couldn't find the same selection of wheels/offsets as in the 5x114.3 pattern, so I investigated the conversion in depth, but after a lot of research, my conclusion was that the extra cost you'd be putting in to converting the hubs would be better spent towards purchasing a REALLY good set of lightweight 5x100 wheels.

Good luck!
