These are now DEFINITELY on my short list, along with the Panda stage rally modded Silver Neomaxes (which they
claim they can build for me with higher rate, shorter than their gravel rally ride height springs, and enough threading/travel on the front dampers, and rear height ajusters, to go from ~.50" lower than factory ride height to about an inch higher than factory).
In other words, a sort of rough/broken TARMAC rally setup.
I also have a call in to Reiger Suspension USA who are claiming to be able to build me the very same as above in their much more affordable (but they did not quote me an actual PRICE yet, LOL) single adjustable damper series (rebound only, like Koni Sport yellows), vs. their stratospherically priced, 3 way adjustable, R2 rally coil over kits.
My only concern at all, is just how 'tough' are these when subjected to hard, VIOLENT sharp impacts.
Like the many 'baby's head' rocks imbedded into rally stage roads, as well as ruts, deep holes and compressions which are
much more likely to cause damage/damper piston 'blowout' than
any curbing on a road course, even at much lower speeds than most hit those on said road courses.
I realize that I am one of the only ones on this whole site (or even in this whole country) with those concerns, save for maybe JDG, who drives at even higher speeds on rallycross courses than I do down the gravel rally stage roads, and a few others on here.
Are the 500s inverted for the front dampers?
