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
