RSB - A+
Installed last weekend
ride is like night and day. car doesnt "float" as much now and I feel glued to the ground during cornering. seems alot safer.

FSTB - D
installed yesterday
I dont think it does anything! I dont feel any diffirence at all. If anything steering seems diffirent. i cant put my finger on why, but it seems really touchy or something. not as precise. but hey it looks cool right?

 

which ones did you buy?

 

RSB - Progress
FSTB - Otto

both from southwest autoworks

 

I put them on in the other order and noticed a difference. Admittedly the FSTB effect was more subtle. I've been happy with the FSTB...

 

FSTB on 5gen almost does nothing. On 4gen that I used to have it made huge difference.
It does look cool as you said.

 

maybe i didnt notice the diffirence with the FSTB because i put it on AFTER the RSB. o well, pretty cosmetic mod.
