Wheel Bolt pattern change, from 5x100 to 5x114.3 or 3.9 to 4.5 Options

[dan0004]

Hi All
after checking available wheel choices for my st204, i decided it was time to change stud pattern from 5x100 to the more common 5x114.3 now i can run so many more choices of wheels.
this is an easy conversion for anyone wanting to upgrade.

the rear hubs and discs have enough meat on them to simply redrill. i used a cnc mill to redrill mine. i needed to weld up one of the access holes to provide enough strenth for 1 stud hole. another option is if you have a dividing head on your lathe, or access to one. or if you have the measuring and drilling techniques to a fine art, you could measure and do it at home.

converting the front was even easier. remove hubs, and purchase a pair of sxa11 rav4 hubs. cv shaft spline and bearing diamaters are exactly the same. press rav4 hubs straight into celica hub carriers with new wheel bearings.
next purchase yourself a pair of xv10 camry front disc rotors (celica rotors wont fit due to the increased hub diameter) put disc rotors straight on, and bolt your original calliper in place.

the whole conversion cost me:
Cnc machine work for rear hubs - bottle of bourbon at $38 (knew someone with cnc mill)
rav4 front hubs - $240 (either $120 ea from toyota, or ~$100 from wreckers)
xv10 camry front rotors new - $70 pair
wheel bearing kit - $100 for both

sorry for poor picture quality, all i had on hand was my mobile phone

this is my first post, i am only new to this forum, so sorry if this is a repost or this has been covered before.

This is a great first post! Very useful information to have. I'm surprised there aren't more 5x114.3 conversions. I assumed it was more difficult than this.

[3WayStunna]

Great looking work there man...ive been seeing this on another forum that i TROLL on, but i was wondering...could supra rotors be used with this? And for the GT4 owners can this be done while retaining the stock calipers?

[block]

I suppose this is the safest and best way of doing it but I've seen people use adapters to change from one bolt pattern to another.

[dan0004]

i assume that the gt4 owners could also do this. i have not measured this all up on one. if someone in the Toowoomba, australia region wants me to check it out for them, shoot me through a pm and ill come look at it for ya.
new pics added for all interested

FYI Camry rear bearing hub assemblies are the same pattern as the Celicas. I verfied this while I was at work, same bolt hole location, size, and rear bore.

So that being said If you buy an assembled rear hub bearing set all you have to do is redrill your rotors. I will be sourcing out these parts for my own vehicle, but like everything else in Hawaii the parts are expensive. I will also be pulling rotors to see what's the best 5x114 rear rotor

Awesome first post, impressive. Welcome.

What year camry?

the bearing is used from 88-00 camrys, but i searched up a 98

Precision - Wheel Bearing And Hub Assembly part # 512009

Celica p/n 512137

its on oreillyauto.com

if anything im going to measure the bore on both hub bearings, maybe we can just use the rear spindle if the lengths are the same

Awesome. I'll be watching this.

[njccmd2002]

this is so dangerous.... LOL

nice contribution. I knew there was a safe way, if now the back was also a bolt on.

MODEL________YEAR_____BOLT PATTERN_________STUD SIZE______HUB/CENTER BORE_______OFFSET
CELICA_______86-96________5x100______________12x1.5____________54.1_______H
CAMRY_______92-UP________5x114.3_____________12x1.5____________60.1______H
CAMRY/solara__99-UP_______5x114.3_____________12x1.5_____________60.1______H
RAV4_________96-UP________5x114.3____________12x1.5_____________67.1______H

according to this data, you'd have to find the rear from a 92+ camery which is when the camery went from 5x100 to 5x114.3
But then what are you going to use as a rear rotor, to ensure it all fits

This is what I have been looking for...

[njccmd2002]

Can you specify, where the bearings came from, are they celicas or camry.

xv camry is that gen 5 camry?

[dan0004]

the xv10 camry is between 1991 and 1996. as we call it here in australia the 'wide body camry' or the 3rd generation camry.
the disc rotors from this model camry fronts slipped straight onto the rav 4 hubs (centre bore same diameter and bolt pattern 5 x 114.3) the overall diameter was the same, and the offset was same. i was then able to bolt my original callipers straight back on.

[trdproven]

i wished there was a more straight forward hub conversion like how other cars are known to have it. ive been researching myself if it is possible besides drilling, i still have nothing.

[stephen_lee]

the only thing now that requires drilling is the rear rotors.

rav4 front hub, xv10 camry front rotors

vcv10 camry rear bearing/hub assy, drilled celica rotor (unless someone finds one that fits...)

[trdproven]

ive been dying to get wide 5 wheels, and wished everything was bolt on. but sometimes we never win, will start looking into this.

for the fronts, anything changes in brake pads or caliper?

[BonzaiCelica]

i was thinking, how about the mr2 hubs. THe rear from the N/A MR2 use the same transmission and axles right? So same hubs??? just not sure about the fronts??

same hub spline probably but definitely different bearings. so you cant just press out the mr2 spindles and press into ours, Fact cuz it's cheaper for me to source out mr2 parts from work
