DIFT> your longer lockers are in, spacers due as are bolts to suit

When do you think I will get them Bill?
Im hopeing today or tomorrow... It'd be nice to get them for Brands Hatch

It's only the bolts that hold the wheels on, so most of the cost should be concentrated there.
The spacers themselves are only flat discs with holes in them.
Fit a good set of bolts and check they are tight on a regular basis. 120Nm according to my manual (Page 189).

I wonder if buying a cheaper spacer from one place and a good set of bolts from another is the way to go?
Guy.

BTW. Once the spacers are fitted, do the longer bolts use the same torque rating as the standard ones?

Its not just flat disks with holes in unless you are going shim spacers...
If rears minimum is 15mm for spigot clearance on hubcentric spacers... and in this instance wheel loads are transferred by spigot not bolts.. Bolts clamp wheel to hubs.
Agree not to use cheap bolts (ever!) but the spacers on this thread are on the whole hubcentric versions, and you dont want cnc'd up shop ones which may not have sufficient wall thickness or material grade to take the spigot loads.
CPU freak ran CNC shop hubcentrics on his mk4 ibiza and in a collision one of the spacer spigots sheared off!

they went out yesterday to you.
should be today/tomorrow delivery (supposed to be next day delivery, but carriers are carriers)

on their way tho

yeah 9ft...maybe i should of made it clear they're 9's

already look like road rollers...but 9ft thats true euro tite! lol

9' - 9 feet

9" - 9 inches

I'm a bit confused here.
As far as I can see the spacer is just that. It keeps the wheel away from the hub by the amount you require.
I Googled and am using this as an example nothing more.

If those aren't discs with holes in them what are they?

Are you saying that it's better to bolt the spacer to the hub and then bolt the wheel to the spacer?
I'd like to get this right because I'm looking to get some 20mm spacers for my car.
Thanks.
Guy.

The wheel bolts don't perform the task of keeping the wheel central on the hub, or taking the weight of the car, they just hold the wheel against the hub.

The wheel itself has a hole in the centre, when you put the wheel on, this hole slides onto a circular spigot on the hub. It is this that takes the cars weight and keeps the wheel centred.

So the spacers need to do 2 things:
1) Slide onto the spigot on the hub (just like the wheel did), and
2) Provide a new spigot for the wheel to slide onto.

Hope this makes sense

20mm spacer fitted. Just need to finish work and find some roundabouts to play with.

V. rubbish comparision photos but oh well.......

yes you are missing something...
hub-centric spacers are not flat are they.. They have a hub spigot machined as part of them, and it is this spigot which takes the load from wheel to actual hub. Bolt are clamps, clamping wheels , through spacers into cars hub.
simple.

Thin spacers... <10mm are flat disk spacers and exactly what you describe, and it is going too thick on these type which then reduces the actual spigot enagegement onto your wheels... which is a bad thing if you leave next to nothing on engagement. Hubcentric is the only safe way to go 20mm/side as you want.

As it happens, I had to put my spare on this evening, so took a couple of photos to explain the spigot / hubcentric thing

Protruding from the hub is the circular spigot:

The wheel locates on the spigot, which takes the load and keeps the wheel central:

So if you put spacers on, first the spacers need to locate on the spigot like the wheel did, AND they have to provide a new spigot for the wheels to locate on. That way all the loads are transferred correctly and everything stays aligned. That's what hubcentric means. (At least I think it does, I'll feel a bit silly if I've got this wrong )

Bill, the spacers are a God send. Gave me much more confidence, was flat out through Surtees by lunch time... Never even contemplated that before without them on. Even got the car on three wheels

Time for Coilovers I think... Just going to struggle with speed bumps... millions round by me

 

[rashcupra]

spacers are great specially wit coilovers im getting my vrs arb on soon too you must do a set of tyres and brake ppads every trackday! <<<dift

 

[DIFT]

Pads usually last 2 trackdays, and a few thousand miles,

Tyres...

Brands pretty much finished off the fronts...

Goodyear F1 slicks

 

[rashcupra]

look at the state of the tyre walls !!!!! thats some cornering good man drive it like ya stole it!
