I went from a true trac w. 4.11's and a 26 in tire cutting 1.56's at best to a full spool w. 4.56's , i plan on running a 28 in tire, with the gears a spool, should i be xpecting better 60 ft's or am i going to be disappointed?

Unless there was something wrong with your true-trac, I don't think a spool is going to do anything.

The lower gears and larger diameter tire will almost always help with traction as long as the lower gears doesn't hurt your topend through the traps (ie push your rpm too high). The taller tire should counter that issue though.

Auto or 6sp?

Should work better... and getting rid of that tru-crap, best thing you could do. (I assume yours is broken from a couple hard launches too)

only one way to find out!

i believe, like others, that a spool and big gears and tires is the key to launching a manual car.

It is a manual....But i guess i got lucky with my true trac, it has seen alot of 6500 launches and it stayed together fine, i actually sold it to get the spool and new gears

Don't forget the 4.56 gears may make it harder to hook up ( depending on how your launching). I tried 4.30's with my manual and it started spinning the tire in the rim. Went back to 4.10's.

That just means you should have screwed the tires to the rim. Going back to another gear because of that is really not the fix.... for all you know you could be going .2 faster with the 4.30 if you just screwed the tires to the rim.

I plan on a fool spool and a set of 4.30s eventually!!! Can't wait!

what about a mini spool? think they could hold up to hard launches?

I went from 4.11's and a tru crap to full spool and 4.56's....Improved .3....The car just feels harder when I launch it.....Don't have to launch it as high as before either...

It also meens the impact to the rear tire was that much harder and thats why I said what I said.

If you're not willing to screw the tires to the rims, then you shouldn't even bother trying to go fast. Period. I don't care what rims you have on the car, or what you paid for them.

If the tire is slipping on the rim it is a safety issue, no differnet then needing a 5 pt harness, better axles, proper length studs, driveshaft loop, etc. Unfortunately, it's something that the track officials can't check.

Unfortunately, until you overstress a tire's carcass and have it come apart at the top end of the track because 1/2 the tire slipped on the rim more then the other 1/2 and the tire gets twisted and then rips apart, you aren't going to understand.
