Megan Racing's 5x100 Hub Conversion to 5x114.3

[infinite012]

You don't just redrill brakes to get a new hub pattern.

That's why there are things like the hub conversion kit on the market.

yeah, you're TOTALLY missing the point here. Did you even read the OP and the link provided? Look:

- *Note: Please make sure the correct size rotors (5x114.3 rotors) are fitted with this kit

1/ Front brake and rotor,
Option1: Upgrade to aftermarket brake kits including calipers and 5x114.3 rotors.
Option2: upgrade to 08-13 stock STI Brembo brake kit (5x114.3 stock rotors), it is direct bolt on
Option3: upgrade to 2010-14 Legacy 2.5GT oem brake kit, re-drill to 5x114.3 on rotors

2/ Rear brake and rotor,
Option1, you can re-drill the original rotor to 5x114.3 and you can bolt them on.

so, my original question was: why can't the fronts be redrilled to 5x114 so they can be used with this kit, and otherwise use stock hardware?

(or in other words, why are we changing calipers at all?)

Yes, it can be done.

My only concern is the stock rotors have small threaded holes (for the rotors to be backed out when stuck to hub). See here:


As long as the 5x114.3mm holes are drilled properly and not too close to the existing holes, you should be fine. Print out a template of 5x114.3mm and see how it overlays with the rotors to be safe.

When I first started swapping Z32 calipers/rotors onto a S13, we never had the luxury of 5 lug hubs. I was able to redrill the rotors to 5x114.3mm (using 1 of the 4x114.3mm holes and drilling 4 more) with zero issues, and virtually every S13/14 guy running 4-lug hubs did the same when upgrading to bigger brakes.

And by the way: It's perfectly safe if you have enough material on the rotor hat, even wheels. See: every 9x114.3mm/9x100mm and dual bolt pattern wheel ever made.

For us, it would have been nice to be able to share wheels between the FRS and our shop s2000s. We already had 7 sets of 5x114.3 wheels - would have been nice to be able to use them.

That being said, we have moved on with the 5x100 setup and haven't had any issues. We've even got a set of dual drilled (5x100 and 5x114.3) wheels to share between the s2000s and FRS.

I was just googing to see if there was a solution for sharing wheels between S2000 and FR-S as I would like to only have to maintain 1 set of track tires at any given time. What wheels did you get that are dual drilled and have a big enough hub bore to accomodate the front axle of the s2k?

Just emailed Megan the other day about these hubs, and they mentioned that they're not on the market at the moment for some reason. They didn't have a date as to when they'd be available again either.

Has anyone tried this setup yet? I am very tempted to go for it, just a little confused on what needs to be done. Do i need to new brakes?

[Skidrcn]

Anyone know of someone running these yet? I know I saw one guy on Instagram running some 5x114.3 hubs but I am not sure what they were. Also do you know of anyone selling them other than Megan Racing? I swear I saw them for like $600.00 somewhere.

Hard Race is the other brand but since they look similar to the Megan ones they're probably from the same manufacturer. I forget which one I heard through the rumor mill was having problems with the bearings.

There's a shop in Japan that modifies your stock knuckle to accomodate a different hub (Legac, R32,etc) so I'm sure it's possible if you find a good fabricator.

Old thread, but I think the reason you can't re-drill the standard front rotors is the Megan / Hardrace front hubs wont fit inside them.

Megan list their 114.3 front and rear hubs as 145mm in diameter, whereas the external diameter of the hub part of the front rotor is 139mm (see image below). The insides got to be smaller so the hubs aint going to fit.

The same measurement on the rear rotors is about 200mm so if they are redrilled, the hubs will fit inside

Do I also need to new brakes using this kit?

Thanks.

I have been running for just under a year all is good

I should make it clear for people.

You can re-drill the rear rotor and it will fit fine

The front you "will" need to change the calipers and rotors because the stock front rotors cannot fit into the Megan/hardace hubs( 145mm diameters of the hub as mentioned) cause its too small making it physically impossible to retro fit with our front rotors with them (139mm hub diameter)

The OP has mentioned a few methods and i think the legacy 2012+ front brake kit is your cheapest bet if your keen

I cannot find 2012+ legacy front brake kit...and I don't want to drop 3k on the Brembo brake kit...granted that's for all 4...what else can be used?

Can I just swap the rotor and retain the same brakes?

Also the rear what rotor do I buy? I'm not a fan of re drilling them...

[Vivos71]

The new WRX's have 5x114.3, would those rotors fit?
