SV2 'Low' Rear Shock Tower

[MrMagoo]

I'm running Simon Moss' set up at the moment, and liking it a lot... it's really changed my opinion of the SV2 as a car and definitely helped with my lap times!

Right now I have the standard rear shock tower fitted, with short Ball Grippas which seems to give very limited rear droop. Would there be any benefit to either going to the lower shock tower or fitting longer Grippas to get more droop?

I'm not sure what tower Simon's using, and I don't really want to buy the lower one if it's not beneficial.
