what size spacers?

[Lude]

my supra has the UK alloys, which are 17"

 

 

beleive they are 9.5J rear,

 

and 8K on the front?? (confirm?)

 

 

what size spacers are going to be required to get them flush with the car?

 

will i need new studs? or are the existing ones be good enough for the amount of flushness i require?

 

heres the look at present

Depends what the offset is mate.

 

If you just get spaces u need longer studs - nightmare job.

 

If u can get away with 15mm or wider u can get hubcentric spacers which are a lot better 4)

You will need hub centric spacers for a start as these are the safest, such as these http://www.europerformance.co.uk/pages/products/manufacturers_subcategory.mhtml?category=wheels;manufacturer=hrwheels Spacers can cause handling issues such as tramling etc but it's not too bad from my experiance.

 

You are correct with your wheel widths.

 

Also take into account that you may require your arches rolling to prevent rubbing.

 

I used a set similar to the wheel adapters on the above link. They worked lovely but I think you may need a webbed inside wheel for that.

 

Spacers have been discussed many times on here. Search is your friend:)

yea thanks,

 

so need the ones with the studs built in yea?

 

like this....

 

 

i wouldnt have it spaced out so far the arches would rub, (the car is pritty slammed!)

 

was thinking, 9.5J is pretty wide for a standard rim, even if bought aftermarket alloys id be in the same boat, (unless bought 10.5-11J)

 

 

 

another question,

 

the car has the Japanese bigger brakes aparently,

 

with my spare fit over it? (have only had the car a few weeks as you can tell!)

If you brought aftermarket wheels the offset is likely to be around the 35 mark rather than the stock 50, therefore the wheels sit out further.

 

The pic is similar to what I had but I cant say for sure if that would be right for stock wheels. The other type come with the longer studs to replace the stock ones. It's a bit of a ball ache changing them but the majority seem to be this type. Performance wise I dont know if one is better or stronger etc. Just that a webbed inner center of the wheel will be needed for the ones in your pic so that the stock studs dont foul the wheel.

As mentioned above hubcentric spacers are the only ones safe to use and at that, 6mm maximum, though some here will say no more than 3mm (and then many would say spacers are not safe full stop )

 

The ones you posted above are unbelievable, never, ever use something like if you value your life!

 

If you have the large brakes the spacer will fit fine, they are universal and fit all models and both stock brake types.

[Jamesy]

Homer the gold ones in his pic above are hubcentric arent they? U threw me when u said never use them. Or are u referring to the universal spacer that requires longer studs?

[Lude]

thanks guys.

 

yea i think just correct offsetted wheels would be best (obv)

 

 

just was thinking of something until then.

 

 

learn something neew about the Supra everyday

No, you are right, I didn't mean hubcentric. I can't remember the name of them now, but they are spacers that retain the orignal bolts (probably just spacers!). Those ones with the secondary bolts should really not be used on a high powered road car without understanding the risks first.

 

A narrow steel spacer that does not shorten the bite length of the nut should be okay though.

 

BTW Lude, if those are stock 17's you already have the *perfect* sized wheel and offset for the supra, to change it will only detract from the handling, tyre wear, etc. Additionally, any change (as with suspension height/spring rate adjustments) will require a complete geometry realignment from a specialist.

[Jamesy]

Gotcha

[Terminator]

I wonder what insurance companies make of the spacers with studs.

woudnt have thaught they really care,

 

as from an insurance point of view they are pointless

[Chiefgroover]

I have use 20mm eibach on my 350Z for years and 8 track days later its perfect, handling actually got better, and I have no regrets.

 

The whole offset witch hunt is a bit rich, dont take it too seriously.

Im sure as long as they're declared the insurers can make their own minds up

Id say they're very far from pointless, after all whats holding the wheels on your car?

[dandan]

What is it that people don't like about a hub centric spacer that uses a second set of studs as opposed to a hubcentric spacers with longer studs in the OE flange?

 

Is it the fact that there are double the fasteners to hold the wheel on?

They change the whole geometry of the car. They cause much higher loads on the suspension and wheel bearings than the car was designed to take. So this is a pretty major modification and potentially dangerous.

 

I have used them on a dedicated track car, but the geo was altered accordingly.

[Dnk]

Now i understand suspension and lowering a car or raising it will alter the camber and the toe but what i dont get is how by adding say a 15 mm thick spacer this changes the camber or the toe by any significant amount ?

 

Yes you'll be adding extra load to the suspension and wheel bearing and it will slightly change the geo under braking or acceleration dependant on the condition of the bushes etc

 

 

If youve got 1 degree of negative camber and come out 15mm then the center line of the wheel will rise by less than 0.5mm ! so the static geo on the wheel wont change hardly at all.

After fitting my rear spacers i had a full geo set up at WIM and he said it was a good thing i'd been as does affect the set up.

I'd love to know how

 

Did they check what your camber and toe were without the spacers fitted ?

I've never been asked my wheel offset by an insurance company - a drop in offset does the same as a spacer in terms of geometry and wheel bearing loading.

 

There aren't many people here running standard wheel width and offset and standard tyres...most run wider wheels and wider tyres and typically less offset so we ought to be able to get a feel for these additional suspension and bearing issues with a few threads an polls.

No mate, fitted the spacers and drove up there fro the Geo - but Tony @ WIM knows geo better than most and i was more than happy to take his advice on this one

[Dnk]

I've just spoke to Chris at Center Gravity and in a nutshell the static camber and toe stay the same but with the extra leverage under acceleration and braking the toe would alter slightly along with the camber but not by huge amounts with a stock wheel and 15mm spacer.

 

He did say this change could be allowed for and didn't see a drama as long as a proper quality hubcentric spacer was used.

 

He added Porsche sell 7.5mm spacers to fit the 911
