Fitting on rims...touching brake caliper

**trism** · 20-05-2008 09:54 PM

yes, some porches have stock wheel spacers, but this is legal, coz they come from factory like it. its done so they can fit big **** off brakes, and push the wheels out to fit guards without having to redesign underpinnings.

they are hadcore welded on but, not just slipped over the studs

i dont see the point in spacers.... just get the right wheels the first time round?

all aftermarket alloys must not exeed more than 2" from stock size and than if you research and buy the right offset for your car there shouldnt be a problem...

spacers are illegal, very dangerous and not good for your car or alloys

most n00bs especially first car or first time wheel buyers don't understand or even know of the concept of offset... these people should just be left alone to learn the hard way like most.

Make sure they fit around the wheel studs and that they fit tight on the centre of the hub and in the centre of the wheel. That way the load is spread across the whole hub and not just on the wheel studs.

coz regardless where you buy them from it is pointless for a wheel shop to balance your tyres coz stupid multifit spacers are unbalanced... only way to really do it somewhat properly is to sticky tape these onto the wheels while they get balanced. and then theres the issue of slightly shorter stud threading as a result of spacers which reduces integrity and holding capacity of the bolts/studs making the ADR against this stupid rice mod completely justifiable... especially considering most people who need these in the first place would have moved to a bigger heavier wheel.

xenonkuraz: Limbo's suggestion about shaving a poofteenth of the layer is the cheapest and possibly only viable option if done correctly and the amount to be removed is VERY minimal and returning/swapping/selling the wheels isnn't an option. pretty sure this is illegal too but:
- it's less noticable especially if you have painted brakes
- detrimental effects to safety of shaving this very minor amount is far less than 4 studs a wheel having 3-10mm less threading depth... man only if you guys have seen a car turning at a roundabout and the wheel coming off mid-turn.. LOL but dangerous....

completely agree, also, adding a larger heavier wheel to a small car like a honda will ONLY occur negative effects (and 90% ppl think it looks stupid)
- negative turning capacity
- negative tyre wear
- negative suspension application and wear
- the above resulting in negative fuel consumption
- the above resulting in negative ride comfortability

lol at people that spend a fortune on 'performance' modifications on thier little car than strap boat anchors onto it to make it 'look good'

the point at which you have to 'grind down your brake caliper' should be the point where you stand back and think 'where have a gone wrong / stuffed up' =/

each to their own... but as always... DYOR (do your own research)

probably a result of the porsche ordering system...

high end porsche are all made to order or for certain application, the reason they may have to use spacers is the rich idiot filling out the form wanting larger/smaller wheels than the car is suppose to have

im not sure about the legality of this for australia but but i would speculate that there would be some fine lines drawn somewhere... i suspect that a car is designed for a size allocation in mind and exceeding the size allocation by more than 2" would be illegal unless otherwise used for track etc

no. the car has spacers in all markets around the world. its not an option. its factory standard.

i was reading this and had to throw my 2 cents in, grinding the caliper is one of the dumbest things i have heard, grinding away at a pressurised oil gallery, hmmmm what happens if you grind to far and underbraking it cracks / brakes? um does that mean you loose pressure in your brake lines causeing the car not to stop?

just buy the right wheel or space it out a few mm, either way grinding calipers, or spacing out is illegal, but i would rather space a wheel then grind away at a system that slows you down......

THe trick is to get them even. DO one side and then match the other side to it.

the most sensible thing naturally is your second paragraph... however your first doesn't make sense...

any hydraulic pressure etc is at the back of the caliper (opposite side to the wheels) unless he has aftermarkets with pistons on both sides which he doesn't....

the part that touches is the outside where the backing plate of the pads rest onto.... but yes... shaving is still only a last resort.

I'm trying to fit the jdm dc2r wheels on my cd5. Was told the offset would match, didn't bother researching. With the dc2r wheels on, there is atleast 5mm of unused thread (opposed to stock alloy).

Have you ever done it before or are you just another internet mechanic?
I've done this on 2 of my cars now cos it was not an option. I upgraded to larger calipers and ground 2-3mm. Both cars were engineered without any problems at all.

THe gallaries are no-where close to the top of the calliper. Its a known practice in alot of places where brake upgrades are required.

The only other real choice is to get different offsets

Spacers are bad... but if you intend on using them, team them up with Extended studs.

Spacers (3mm), which I use for the track on stock studs to fit my stock DC2R rims over my Spoon Calipers.

ARP Extended studs - to give you the extra length that spacers take up.

http://cgi.ebay.com/ebaymotors/ARP-E...spagenameZWD2V

If you get the extended studs.. you'll be alright... just make sure you check your nuts every now and then.. and tighten them. I find my studs become a little loose when using them. But meh... I still use them - even though I am quite against them.
