I have a really hard time racing anyone from a stop, is it cause of my gears, the fact that i dont have a posi rear, or is there something else i could be doin to roll race better

 

why dont you have a posi rear?

 

posi, suspension, tires

 

4.11's and street tires may be why you can't hook..

 

i have a 2000 z28 and i dont think i have posi how much is it 4 a diffrential with posi.

 

check your RPO codes on the sticker on the driver door, you should have G80 for limited slip.

 

 

get some BFGs DRs you will hook every time i promise.

 

i meant to get a posi but kinda cheaped out im replacing it when i go down to 373 and will my 10 bolt hold up with bfgs dr's

 

Your 10 bolt will be a crap shoot on any sticky tire. It might last but for how long? Can't really say.

 

so should i or shouldnt i get them i haver michelin pilot sports 2's on there now

 

Well i have falken ziex ze 512s on my car and I hook up okay. I can't stall at all cuz if I do, I spin like a mother. I have a buddy here with an ss with a small stall on it and some 3.73s and he runs nitto 555drs and he has no prob hooking at like 3000 rpms.

 

yeah if you get a good tire you will be good, as for the rearend time will tell!!
