Been shopping the RideTech 12263110 coilovers for the Marauder. Cheapest I've found them is here:
https://www.carid.com/ridetech/hq-se...-12263110.html
$750 with free shipping, a savings of $780 buying from Summit or $799 buying direct from RideTech.
Never heard of the website, though, and concerned about its reputability.
