Can anyone tell me what diameter axle (3/32 " ?) is fitted as standard to Spirit cars such as the BMW 2002 ?

Hi Steve,

Spirit axles are 2.44mm, and usually very soft and not very straight !!.

Avant Slot : 2.34
Scalextric : 2.35
Slotit Hollow : 2.35
NSR : 2.36
Fly std : 2.38
Slotit : 2.38
SCX : 2.40
Cartrix : 2.40
Spirit : 2.44
Ninco : 2.46
Fly Racing : 2.48

These are only my measurements of cars I have, they can not be guaranteed !!.

Note that the size does make a difference, an NSR hub for eg won't go easily on a Slotit axle !!.

Also, if you replace the Spirit axle with Slotit you must swap the bearings too !!.

However,

Without measuring, the 406 axles take slot it wheels so it may depend upon the model you have, the 205 i have is a larger diameter axle which will not take slot it wheels.

I guess you will need to measure or try out other axles?

The axles on my spirit 406 fit perfect in nsr bearings. And the slot-it wheels too.

Ey Up,

I think it is good that we have so many eager contributors to the forum.

DRH, you are right, they are different.

You will find that the axles on the Spirit Pug 406 are in fact different to the axles fitted to the standard Spirit BMW.

You could have inferred that from the original question "such as fitted to standard Spirit cars such as the BMW 2002".

SCS, partially right, "must try harder" ??.

The Spirit axles are pretty "rough", have you ever rolled one across a flatting block ??.

Never mind, basically, one's personal standards define "fit perfect" .

As an Engineer they don't "fit perfect" !!. Maybe your version of "perfect" is very different to anybody else ??.

How strange that anybody who professes to know what they are doing, would wish to run a Spirit axle in NSR bearings and fit Slotit hubs, Wow ??!!.

CJA, not sure where you get QUOTE Slotit : 2.38 from
I have ten here and they are all between 2.34 and 2.35mm.
Now I'm going to have to check all my cars. Thanks, as if I had nothing better to do.


SCC have Slot.It Steel ProAxle's - rectified and tempered - 3/32" (2.38mm) diameter., which it is. 2.38125. But in the real world of metric. I is not so simple.
2.35mm = 0.092519" = 2.34998mm. 3/32 = 0.09375 = 2.38125. or a snug fit, tight fit.
Slot.it Axle, SCC racing bearings. Wheels. Down to you, that fit a Slot axle.

Interesting thoughts.

Our touring car class at the club Burnt oak now Nascot Wood is completly dominated bt the 406 still running with the original back axle and original plastic gears, we even have down graded the motors to NC5 as they are so quick with the original motor.

I have slot it wheels on both of them, they both are superb cars.

There does not seem to be the need to run slot it axles as the original axle and gear are just as quick as those whom have changed to slot it.

I have not tried your test to see if they are perfect.

I do however run slot it gear in all other classes that we allow.

Thanks a lot for all your contributions.
My Spirit BMW 2002 (Pneuhoge, # 68) despite having so called 'calibrated ' components, ran terribly out of the box, with all kinds of fouling issues (pinion, motor shaft, crown) taking place and a front axle that was a bit too wide. Once these problems were sorted out however, the car became an absolue blast to drive and is one of my most enjoyable. Not very competitive in my club's Historic Saloon class however, which is for unmodified vintage saloons. Most others here run the Scaley Escorts and Cortinas . While the BMW is faster in a straight line, it is no match on the corners because, due to magnet placement so far forward, it is very tail-happy, compared to the Scalextric cars which almost feel glued to the track in comparison. My problem is that one of my rear rims has become loose so is now glued on to the axle. I would like a better fix than this so was wondering if I could adapt standard rims/tyres of roughly the same size (to keep within the 'unmodified' aspect of the rules) from another brand which would work on the BMW's axles as I have no idea where to get replacement Spirit rims for this car.

Yes. They do need a rebuild!

Since the axles are 3/32 most plastic rims will fit the rear. Slot.it one may take the insert from the current wheel??

The fronts are narrow though.

If the Escorts are good then maybe swap the complete assembly to them.

Chris's knowledge on axles!! He does make some great cars!!

The early Spirit cars were larger. The later ones are 2.38 (ish) and are definately ok in NSR bearings.

Having said that I have run the Spirit bearing with slot.it axles just do let Chris know as I sense this is a cardinal sin.
