PAG 15 wheels!

[davehanman]

On the RAC 75 and Safari cars that Vince posted up earlier in the thread, the front wheel is Cromodora 14" (as per ferrari Dino), and the rear is an aftermarket Campy 14" Rim, (also for Dino). Of course, brake sizing is compromised using these wheels, which is why they're not seen so often on the '76 cars (though Waldegard still used them for Safari in 1976)

I'm just trying to compare my Compomotive Split rims with the PAG's and the Hawk Coffin Spokes and would like to know the offset / ET measurement for the coffin spokes 12" and 8", anyone know?

Hi,

the ET measurement for the coffin spokes are:

ET -34 (12" rim)
ET 10 (8"rim)

Thanks Enzo, I'll see how they compare.

Could it be that the ET on the 8" coffinspoke could be different from manufacturer to manufacturer?

I discussed with Gerry H, Jonathan at G4W and Barry at Compomotive to get my PAG 15 in 8" to be the same as Gerry H Coffinspoke wheels.
And the number that came up on the 8" is ET 00 so my PAG 15 is ET 00

However I need a small spacer in front on the PAG wheels to clear the calipper so a bot more posetive offset would have been great, but they are perfect for the rear with the TB15´s in 270 width, filling it out.
John Whalley have not tried on the coffinspokes yet, so should find out soon if I need a spacer on the front to clear the calipper on them as well.

Have a good weekend!

Hi René,

i did also measure ET 0 but Gerry say it's ET 10

i think it's always better to mount the brakes and take the measurements!
and to order like them.

i do that with my TMB rim's! on my Allora.

and Jonathan make it also like your measurements if they are in to the available dimensions.

PAG 15 wheel Spec
Diameter 15"
Width 8"
Offset -24 to +12
PCD Various

i mean that's the best solution, Enzo

its correct to mount the wheels then fit the brakes to suit after, otherwise you alter the track, scrub radius and a whole host of other things. Geometry first, brake package after.

Ok I've been busy with tape measure trying to work out the off set's to order for the PAG's.

My current setup is:-

Image split rims

Front 8x15 ET -14mm
Rear 12x15 ET -26mm with 9mm spacers so -35mm

There seems to be some confusion regarding the Hawk Coffin Spokes ET measurements, but what I would say is that if a possitive ET was used on the front the wheel rim would run very close the top ball joint, with an ET 0 the clearance on my car using 4 stud hubs and Thema Turbo disks would only be 2-3mm to the ball joint cover and approx 6mm to the joint.

I don't know if the 5 stud conversion has a different hub face position to my set up, could someone with the coffins on measure the distance between the wheel rim and the top ball joint on a Hawk to confirm my findings.

Hi,

the ET measurement for the coffin spokes are:

ET -34 (12" rim)
ET 10 (8"rim)

5 stud coffins are ET0 and ET-50 as stamped on the wheels. Not sure how accurate these figures acually are as I measured the rear rim and worked it to out be ET45. Will double check.

I agree with Graham, Hawk wheels are- Front ET 0, Rear ET -45.
Roin Technologies wheels are- Front ET 7, Rear ET -36.5,
TMB Racing are quoted as- Front ET 21(?), Rear ET -32.
Not sure what is going on with the TMB fronts. All are listed as 8 x 15" Front, 12 x 15" rear.
Roin also do a 9 x 15" ET -14.7 & a 10 x 15" ET -25.
