stud pattern question

[mattywood]

Can anyone tell me if all Datsuns motor vehicles with 4 wheels studs have the same stud pattern as the roadster?

[drewnamis]

no they don't, but most (especially vintage) datsuns should be 4x114.4

[mattywood]

Thanks. Do you know which models are the same?

Most of the rear wheel drive cars are the same stud pattern - 1600, 180B, 200B, bluebird, stanza, 240Z, 260Z, 280ZX, 240K, any 4-stud skylines (C210, R30, R31), S13 silvias (these are the australian model names, BTW).

Steer clear of front wheel drive stuff - pulsars and the like - they are mostly 4 x 100. There may be a few exceptions (I think the front wheel drive pintara's and bluebirds are 4x114.3 for instance), but generally RWD should be OK and FWD is different.

Another factor to consider is the centre hole in the wheel. I picked up my new fairlady yesterday which had flat / perished front tyres, so I took down a pair of R31 skyline wheels and tyres I had lying round in order to get it rolling easily. The centre hole was too small and wouldn't allow the wheels to pull up tight on the fairlady hub.

what did you end up using?

The front hubs a very bulky, not many modern wheels will clear them with their small centre hole.
In an emergency, swap the rears to the front and fit the modern wheel to the rear.
The rear brake drum is more suitable for a variety of wheels.
Of course this will only work if the rears are stock or do have a large centre hole

I followed that great Australian tradition of "She'll be right mate"

The hub is slightly tapered and the centre hole in the wheel was only a little bit too small. The wheel nuts caught by a few threads, just enough to hold it secure enough to roll the fairlady out of the seller's shed and up onto my trailer. It stopped about 10mm short of the wheel meeting up with the mounting face on the hub.

It was marginally OK for the 6 hour return trip up the highway on the trailer. I was tempted to put the old flat tyres back on just in case, but ran out of enthusiasm after pushing the fairlady up a long, sloping driveway then having to use an ancient block and tackle (and lots of brute force) to drag it up on the trailer because my brand new cheap chinese winch decided to play up

which other makes can you use on roadsters?

[spl310]

Lots of Toyotas used the same pattern. Ford 4 lug cars prior to the early 70's (pre Mustang II days) had the same pattern. Chevy Corvair. There are more.

Since we're on the topic of studs.....

Anyone know where to source long studs for racing that have the same knurl/head as the roadsters stock parts? Haven't located the right combo yet.

[Nissanman]

In answer to your Q, no.
However, for racing, my suggestion would be to have the flanges re-drilled to accept the more readily available 1/2" or 12mm diam. extra long studs.
ARP, NISMO etc. sell wheels studs that will be more than adequate.

Interchange mentions Corvair studs, longer than stock. Maybe a set of racing Corvair studs would be even longer?

[SinrgRacing]

Thanks for the leads. If I don't have to drill, all the better. I'll see if i can nab a corvair set and see.

[DatsunBucky]

The closest ARP has in their catalog is 100-7701 for late GM with drum brakes. The knurl is larger diameter than the stockers, so you'll need to come up with a way to make them fit. PM me for how I did mine, as I don't want to publish it here.

Hi everyone I am so confused what car rims will fit a 1969 Datsun 2000. Will a 1991 Nissan stanza rim for it ? Thanks
