I'll get the straight skinny on every thing. He purchased the suspension parts from one company that was bought out by the company that makes the R&P kit. The guy that owns the Stang restores/builds them for a living and also provides parts for all the local Stang owners at a reasonable price.
Yes, the coil overs are fully adjustable as well as the upper and lower control arms. He drives the car on a road course and has a special alignment that is not conducive to every day driving, like 3 degrees positive toe. On the track, he runs three 20 min periods with an hour in between for adjustments, cooling etc. He is installing 17" wheels around and discs in the rear before returning to the course next month. The R&P is three turns stop to stop but there is a 2.5 turns option.
