[RACER X #99]

Keith,
I installed the trigo's with adapters on my older Contemporary.
I had to shorten the lower control arms and had new half shafts made. If you are starting out new you probably should to go for the original pin drive set up. It probably won't cost much more.

BTW I spend a lot of time on the track and I use 5 lug bolt ons for that use. The wheels are much cheaper plus I carry 4 spares with me. this could be very expensive if I had to have 12 trigo wheels.
