After market steering wheel boss query

Hi, am thinking of getting one of these http://www.ompracing.it/detail.html?productcode=OD/1985

Wondering what other exigers have used for the boss, what depth to use…

Am thinking this… Steering Wheel Adaptor | EliseParts

although not sure 20 30 or 50 mm

Thanks in advance

I looked at the Kubic as I have had OMP wheels before.
Decided on the superquaddro in the end - Kubic looked nice but opp locking might have been tricky - I’d suggest you hold both before making a decision :wink:
Boss wise I just went for a standard Momo boss which fits the exige fine
