(Note: Drop levels specific to V6 engined FTOs, the drop on the GS will be less)
At present, I have Espelirs fitted on standard shocks and for my money, they're too hard for road use. They would be perfect for track use however.
The Teins looks like a good balance in terms of drop vs spring rate and would suit track and road use.
In terms of overall value for money, good ride quality and a reasonable drop, I would be inclined to go with what we all know is the best comparable choice - Apex.
