VORRA and BITD allow long travel (under 80" wide) in the stock/sportsman class. Most other orgs that I have looked at (NORRA, DP4, SCORE) long travel would move you into the mod class.You will most likely be at or near 70.
I would do the stock shocks up and race it first...before you spend the 7k on a long travel.
Those RG arms are strong though- as we saw with Crawlr's hit.
May take you out of stock class rules with any other susp mods anyway.
Gonna start with springs first and see how much that affects it, then most likely do valving.
I did outermost edge of the lug, top of the tire, passed the tape measure straight through above the steering rack... And bounced the front end a few times, it definitely does sit high after letting it down off the jack.To the edge of the tire at the top or bottom? They do camber negative some.
I am at 66.5- don't forget to re-compress the suspension before you measure. These things sit up some after you lower the jack- will narrow the front. I have about 14-14.5 ride height to frame.
