VRP pistons work best with emulsion style(after my independent testing)....with that said....they woke up my Tekno both the 410.3 and Eb48.3 right up. I use 5 /1.3 mm hole pistons with 20 wt oil and they feel like 45wt/pack with 20wt/rebound.I can run the car at 23/24mm rideheight and will not bottom out. They are awesome !! Kinda like MIP bypass system.
Just make sure you 2 washers for each pistons,one for the top and one for the bottom or they'll break. The kits only supply 2 washers for 2 pistons !!
