S2 wheels on an S1?

[smee]

What's the PCD for an S2 and did it change from k series to toyota?
If it's 4x100 then surely these are what you need?

If weight is what's bothering you surely bigger wheels are going to be heavier?

PCD is 4x 100 on all S2 cars. Offset changes at the rear (more IIRC) with the Toyota engine.

Hubcentric spaers is one way to do it, but I'm not sure that the PCD will be 100% for both K & Yota engine set-ups.

4x100 is a very common wheel fixing pattern; may be able to get a light weight set of 15/16" wheels easier with that PCD. Again S1 offsets are pretty different from most modern cars, so wheels may not be cast with little enough offset available.

If you're just after something a bit lighter than victories, bell and colvill are selling off the 12 spoke s1 rimstock wheels for around £300 a set. I think they're still available, I bought a set around a month ago.
I don't think they suit it very well, but they're very cheap for spanking new wheels!

The S1 stack speedo input will likely cope with the S2 sensor output as the S1 uses a similar VR (variable reluctance) sensor - if not it is not hard to adapt the signal so that it will work - I can help you with that if it becomes an issue. The S2 may produce more/less pulses per revolution, however, so you may need a frequency scaling component in there to adapt that part of it - easier than it sounds

s1 is 41 pulse/turn
S2 is 32 (From memory)

back to the original question, easier just to use hub-adaptors:



this not only adds 25mm spacing, but also converts to 4x100PCD

this means instead of needed ~ET10 wheels (somewhat hard to find) you now are looking for ET~35, much more common.

all that said, running 16/17" rims on an S1 is a bad idea, the overall diameters are just too much and it screws your geometry unless you raise the ride hight accordingly (and even then you still have clearance issues with the clams)
