(apologies, I've just seen this)
I've the SSL setup on my Aero S5: the before may sound familiar - the front end is too stiff, with too little roll. The rear is too soft. They don't feel like they're part of the same setup - and while it might work with 125bhp, with 3 times that it produces a nervous ride and tricky handling.
SSL offered me a sportier rear anti roll bar - they're made to order, so just ask. The two ends of the car now work together so it's more fun to drive; my regular passenger noticed the ride is much more comfortable. I've no regrets about changing, and now make far more use of the car.
Will
