We've recently swapped out the front shocks on ours from Menscer valved Afco's to Santhuffs. By the time Menscer had done the work they were around the same price. The car is a wheelstander and has come down hard a few times and damaged stuff in the past, the Santhuffs seem to cope much better on the landing with no bounce like the Afco's. Car 60fts better with the Santhuffs but that may be because I have more confidence off the line now
