OK guys as it sits now my car is unmodded besides a freeflowing exaust, cone filter, and emmissions removal. I am planning on putting about 300 into her for the holidays. Heres a list of things I was planning on buying. Which do you think is more important and/or give the better benefit

1) safc II
2) rb header
3)an lsd
4)front and rear strut bars

Also, Is it true that automatic cars came factory with a shittier last gear than 5spd's?

 

That would be true, they came with 3.9 compared to the 4.1. S-AFC & full exhaust are your best two for giving it some kick. A LSD is fun if you have big parking lots and some rain, but other than that there's not much you need

 

i 2nd SonicRaT's advice

 

So a gxl lsd will have the 4.1 gear in addition to the fact that its lsd, right? Im definetely getting the diff soon. I was putting my priority on the safc II but then i keep seeing posts about needing it to tune mods, and I really dont have many. Thanks for responding.

 

Yes, a GXL would have the 4.1LSD (so long as it's not an automatic GXL, haha)
