Just saw these on a web site. They are only $150 for front and rear lower tie brace. I'm having trouble putting power to the ground and was wondering if these might help. Anybody with reviews on these products.

 

i think i know what you are talking about....the ones by gt spec, right? i think the lateral bar will help a bit in handling response but im not too convinced that the other two will help that much, considering that the Z's chassis is pretty damn stiff as is.
