I've got mine on koni top adjustables and Ahmed Bayjoo springs...fitted them on the advice of Mike Rainbird...totally transformed the car! instead of squating and spinning the wheels now it grips like fook and the stance is perfect!

Got a chunky anti roll bar and a poly diff mount to go on next

As far as I'm aware if you fit an adjustable rear beam, you shouldnt have any of the camber issues normally associated with lowering a rwd saff as you can just dial it out...would love an adjustable rear beam myself but I'm too much of a minge to fork out 900notes
