Do you mean strut tower bar? If so a few people run them havent really heard they made that much of a difference on a fwd car when the struts are already so close in on the chassis/firewall already..
I like how strut tower braces look even if they don't add much performance to the suspension. I may end up making one if nothing comes available.
The manual says to increase the tire pressure further, 2-3 psi, in winter (possibly only when using winter tires). I like the ride how it is.
