Ok, so been researching different ratio steering, specific to my project, yet it could be apply to a Slingshot as well...
So, stock Slingshot steering is roughly 3 complete turns lock to lock from what is posted in other posts...
@Ghost measured the rack travel at roughly 3" lock to lock...
Unisteer:
There are 3 ratio's listed in Red below, the 3 turns that the Slingshot has, combined with the 3" of travel tells us the Slingshot has basically the same as the slowest ratio listed below.
So, if anyone wants a custom rack built, the 1.3" of rack travel per steering wheel rotation or the 1.5" of rack travel per rotation of the steering will give them a faster ratio...
I need to do some additional research for my project, but thought this info may be of interest to Slingshot owners.
Mike.
