im thinking about puting a 8mm wheel spacer to the rear . do i need longer studs if so where can i buy them from/part # ?

 

a) I'm not sure you can even get an 8mm spacer - only seen 5mm increments

b) any decent spacers should come with their own studs, afaik

 

Stick with name brand spacers if you're going to get them(Ichiba, H&R, etc), the kits should come with everything you need, 5mm kits come with 35mm studs and 10mm kits come with 45mm ones I believe.

 

i had them laying around from my 2007 corolla i put them on today they looked good but i wasnt sure if i needed longer studs im sure theyre the cheap ones i got them from pepboys i meassured them theyre 5/16'' only for the back btw

 

^ yea thats not the safest thing to do, don't install them unless you get some longer studs.
