17" Rims and tyres

Your 3mm spacers are the slip-on type and just go over your standard hub bolts. 25mm spacers are bolt-on, they use your original bolts to secure the spacers to the hubs, and have new bolts protruding from the spacer to bolt the wheels onto. It should probably be noted at this point that neither type is legal for road use in Australia.

you shouldn't have the stress on the lugs at all due to wideness. i don't know how it works with spacers, but it should be all resting on the hub bore

 

Sry for the late reply....yes marc i had to roll the fronts more....yes my spacers are bolt on...i wouldnt trust slip ons....ill seeis i can find a pic with them on to give u an example.

 

Fitting spacers and aftermarket rims - tips

The slip on type is illegal here too

The bolt-on's must have a lip resembling the lip on the hub which takes the weight of the car, all the outer bolts do is to hold the rim to the spacer.
The inner nuts bolt to your existing studs



Note these have conical nuts which fit into the spacer, most a/m rims will require you to switch to outer conical nuts too as the Toyota type are designed to go into the bolt holes and won't work with normal rims, giving you only a few threads which is also dangerous

There are many spacers available which don't have a lip - THEY ARE DANGEROUS! as 1) the bolts do all the work 2) the bolts will eventually snap
They are available resembling the bolt-ons shown above or as slip-on's like these - they are illegal and dangerous



Be careful what you buy and check you have the right nuts to match your rims!, the threads on Subaru etc are different too - be careful

 

heres a look at my car without spacers on the rear.



old pic i know....ive been running these sam,e spacers without problems for over 3 years..

with spacers on



and here are the spacers themselves

bolt on type at 25mm in thickness

 

So the way im running now is 205/40/17 in front without spacers 205/45/17 in re ar with 25mm spacers... my front has blown shocks and cut springs... my rears r stock height.
The offset is +42 right now
When i buy new wheels this will be my set up....205/45/16 in front with rim offset at +37....my rears will be 215/45/16 with an offset of +14. Sithout the use of spacers
