Just installed my RSB saturday morning..
I haven't stopped carving corners since
It's just so much fun! The car actually oversteers!
Woo hoo!
Now I just need to wear out these stock struts so I can get some Koni's...

 

Yeah, they are great! A lot of people here say that the FSTB is the biggest handling improvement, but I think that the RSB beats it easily.

Have you played with the adjustment on the end links? I set mine in the middle when I installed it and haven't bothered to mess with it.

 

the first few hours I had this installed. I didn't have the right 14mm extension though so I couldn't tighten the back too U-bolts enough. SQUEAK SQUEAK SQUEAK. Needless to say I bought the extension the next day and it hasn't made a noise since. Definately a badass piece of gear =)
