Hello guys,

i'm going to buy a dogbox for my Bseries y21 trans, but as usually wich one?

I need help to understand how to choose and what brands are a safe and performance solution?
do someone can help me. My b16 is going to do around 600hp and i run 22.5-13x 9 front.
How can i choose gear and final drive ratios?

help please!

 

MFactory has the gear calculator on their site, that could aid in your decision.

www.teammfactory.com

 

Yes i've already done but just to know what is the best solution for the money.
Anyone uses PPG or mfactory? Which one is the best for drag apllications?
i would like to use 4.05 final drive but feels to me too long and i won't loose too much power at low rpm
Anyone?

 

The best solution is the one which offers the best ratios for your application. Don't just buy a gearset because someone here says "it's the dogs *****". Do some more research into your application and what YOU require from the gearset.

AFAIK, no one offers a 4.05 Final Drive with their dog gear sets, although you may be able to get one custom made.
