Bertone X1/9 Speedline Phone Dials wheels on Beta Coupe

[Lancia12]

Does anyone know if '87-'88 Bertone X1/9 Speedline "Phone Dial" wheels (see photo) will fit a '75-'76 Beta Coupe?

Speedline Wheel Specs Are:
4x98
13"x5.5"
102mm backspace

If so, are spacers needed?

Any photos?

Thanks

4x98 is correct
13x5.5  - 1" smaller than standard beta wheels but shouldn't be a problem provided they clear the calipers
102mm backspace - rather than the backspace you need to measure the offset - it should be stamped on the rim as ET40 or similar. Betas were ET34 so if those wheels are ET40 you'd need a 5 or 6mm spacer. In fact you could probably get away with using two or the standard spacers.

Having done this swap in the other direction, I don't believe they will fit over the brake callipers. As for offset, they will stick out about 15mm more than Beta wheels. I calculate the ET to be 22mm for the X1/9 wheels.
