    Default G8 GT owners with 3.27,3.45 or 3.70 gears (diffs) come on in.... Need some info.

    Ok guys I am doing research here on what to expect when I instal my diff. What type of improvements did you have on the 1/4 mile or 1/8 mile when you installed your gears/diff??

    I already made up mind I am getting 3.45 Camaro diff from Pace Performance.. I am just wondering what type of improvements to expect. I am guessing more or less 1-2 tenths on the 1/4mile??

    Right now I am running 12.1@116mph with the DA 3153 consistently..

    I gotta get ready for your maggie... I am stopping after this maybe a little porting here and there just to squeeze out every ounce of HP I can. I dont want my car faster than a 11.5 or else I will have to roll cage the car up and I dont want to do that... Maybe a 100 shot for the glory run at the end of the day before they kick me out awwww to many plans....
