Sorry If i sound nieve but surely if they're used in high power, high stressed drift car's without issue's it'll be ok for my car.. right?

I wouldn't say drift cars are highly stressed except for maybe their cooling systems. They put bugger all sideways load on the front or rear wheels, unlike circuit racing.

Any g force while cornering is putting a cyclic tension on the wheel studs as the wheel rotates. If the aluminium surrounding the wheel studs starts to wear, and the holes (in which the studs go through) elongate, then it may develop to the point of the spacer failing totally and your wheel coming off.

The other biggest force is from braking which is trying to twist the wheel studs around a centrepoint which is in line with the centre of the wheel bearing. Ditto above, if the aluminium starts to wear and the holes start to elongate.....and so on.

But, I don't think this would ever be a problem with street tyres and street driving. But I would not use them in competition with semislicks or slicks.
 
Because rims aint cheap, and i don't wanna replace P1's, coz i like 'em.

And what offset/rims would actually clear 3kgt calipers then?

Maybe i can get new hubs made up :p

You are in the exact situation that I am in!...and I just sold my p1's for the same reason.
I have just had a set of 6mm spacers made up from a machine shop and will be replacing my studs as my new rims still require spacers to clear but fit better than the buddyclubs.

I have a set of sparco 17 inch rims that are used for track work and clear the brakes easily without spacers, I am unsure of the offset of them but the big factor of getting rims to fit is the spoke design.

If you are planning on doing track work I would consider finding a cheap set of rims that do not require spacers to fit.
 
Awesome idea :) thanks for that.

Spacers for street, and more suitable rims for track. seems logical. I just need to figure out what spacers would suit, etc.

I'll give just jap a call now and see what they've got to say about their product line.
 
Just jap say they've never had a problem, unless people haven't fitted the hubcentric rings i think, to take up the gap between the rims/hub, in which case, people have bent the studs. The guy said that it was a fitting issue, not product fault.

The guy said he uses 30mm ones on trackdays, hill climbs, etc. and never had a problem.

^ this is the bolt on type am referring to.

15mm bolt on ones for me then it seems :)
 
After consulting some of my more knowledgable friends, I'm iffy about the idea of bolt ons, because 15mm is too big.

Having the front wheels sticking so far out from where they're meant to be will alter steering and handling too much - potentially unsafe. I might get floating type and get longer bolts if i must, else save for a while until i can afford new rims... but even then, i dunno what offset i'll need.

I dont see how it would be that detrimental it became unsafe.

Thats the worst option.
dont get longer studs, plus fitting them is a shit of a job.
 
I was told by someone who is running 15mm+ spacers that the extra track helps with turn in, the only downside is that you might have to run max neg camber to keep the tyres in the guards?..
which is not very street friendly!
 
apparently bigger spacers means that, for front wheels: more steering torque. so if you do something stupid and hit a kurb or something, steering wheel goes nuts, and you break hands :)

also the more you get off the centreline of the strut to the wheel
the harder it is to turn and more load on rack/ p/s pump etc and all
other suspension components
 
I've just bought a new set of rims. I've had to use 3mm spacers to get it to fit. But the workshop also put in hub rings to more of the load is placed on the hub than the actual bolts. Is this ok to run on the streets and few spirited drives every now and then?

The spacers were only used because the center cap was not fitting properly. I know its illegal to run spacers but just want to know everyones opinion - if having hub rings and 3mm spacers not dangerous then I'll just leave them on.

Worse case scenario I'll take them off and have no center caps.

Your thoughts please.
 
I would consider removing the centre caps to avoid the use of spacers if that is the only reason you require them? The general reason for running them is to get rim/brake clearance.
As long as your studs are in good condition and you still have plenty of thread remaining for the lug nuts you should be ok.
I have to run the same setup on my GSR and no its not ideal, but have no other option.
