ASM four point if you are running a intake.
ARC if your running boost

 

they don't strengthen the same areas. different types of products.

again, i strongly suggest not buying ti reinforcement bars. go for aluminum, steel, or carbon.

 

yeah, an x-brace is not the same as the "x" in a 4-pt strut bar.

 

the 4pt Strut bar goes in the engine bay.

the Spoon X-brace goes underneath the car.
Spoon Strut bar is a 2pt strut bar.


you can install the 4pt struct bar (ASM, S2X, or T1R) together with your Spoon X-brace that goes underneath.

hope that clears it up.

 

Oh ok thanks...

So with plans of S/Cing the s2k in the future, I will probably go with a non-TI strut bar for reasons discussed above, and only a 2pt version so I do not take up the addition space needed for s/c....

Would adding an x-brace make much of a difference to stiffen the front in addition to the 2pt strut?

Basically, I think I will keep my suspension stock but I would like to stiffen it a bit hence the strut bars and such. At the same time I have been told not to change the sway bars with stock suspension as it can make the car "twitchy".

 

i think the use of reinforcement bars are controversial on this board. personally, i have them all (front / rear tower bars, x-brace, "ladder" brace, rear bottom brace, roll bar/cage)--i don't know if it's just mental or what, but it does feel stiffer to me, and provides some extra feel. but again, could all be in my head--but whatever works right?... ha ha. the car's structure with all the mods is certainly much more rigid than any other previous car i've owned though--that difference is definitely noticeable.

as for sway bars, they have to be matched to how you setup your car (rims/tires/suspension). but i think stock is fine until you know how you want to change them.
