First, congratulations on your second place finish in 2WD at 100AW!
Anyways, it appears that the Safe Drives website is either down, or no longer exists. I assume that Safe Drives was the only distributor of the Simpson Hybrid HANS restraint that had a rent-to-own system.
The Hybrid Sport, their cheapest restraint, costs $600. It's still a large quantity of cash. Is there any other store that has a rental program? The $500 could be a setback for a while.
Also, apparently there is/was a Lotus Exige rally car? I wholeheartily approve.
