a race tranny?? you mean you want something with a dog style? short gears? lsd? cyro gears? what the f**ka re you talking about!!!?!!?! be a little more specific. oh and that gearspeed glasstop crx makes me moist.
If you buy a full quaife tranny, you will drop a min of .30 from your times. Thats with having clutch,fly and lsd prior to this. I have a few friends that are pro's that use this.
