I am buying a new exhaust and I need SFCs too.

Which should I purchase first?

Also after countless threads on SFC's I still can't decide on one.

Inner or outer for a hard top?
I just want to decrease any flex that is causing cracking on the door frame corner.

I was thinking either Sphons or Alston and I cannot get both right now.

I plan on doing some street shenanigans with launches and the like, but I can't deal with the bending threat.

Thanks in advance.

 

Well, if you are buying both the exhaust and SFCs pre-made, and if there's going to be interference...I guess it doesn't matter which you buy first. You'll have to deal with those issues either way. ???

 

SFC's should be one of, if not the, first mod on a thirdgen. Once you install them, you'll understand why.

 

Buy the subframe connectors first. I would go with the outer style by UMI (thats who I have) but other brands are also comparable-Whatever brand you can get a good deal on. I've heard through this website that the Jegs aren't half bad but things may need altered. The inner connectors like the Alstons are an ongoing debate here but most people agree that they should go on after you already have outers. I believe that inner subframe connectors will not alter your class for autocross but outers will.
