AlterKtion - True Pro-Touring Suspension

These three guys are giving you the best info you can get (short of talking to Bill himself). Abodyjoe is using alterKtion and streetlynx with coilovers. Momoparman is also using the alterKtion and streetlynx setups both with air ride. Autoxcuda is about the only guy I know that has tried about every suspension setup out there for A bodies, minus the alterKtion and streetlynx setups. I would take their advice and give RMS a call.
