what are the pros and cons of changing your rear gear ratios.

 

More torque to the tires in each gear, the trade-off is higher rev's in each gear

 

DO IT DO IT DO IT!!! I just had 4.10's put in and I believe they should have come stock. No one buys a sports car for gas milage anyways! LOL

 

Good luck this weekend dude! when I first got the Nitto's the best 60' I could get was a mid 1.9 ... it takes a while for the tires to break in... I wish I woulda learned to drive em sooner (back when I was NA) so I coulda gave you a time to shoot for ... After a couple months you should be able to get your 60's in the 1.8's and get some really good times.

 

i just did it, but its cause i ripped my gears to shred racing it, i had to replace my entire rear end, and the guy asked me if i wanted the same gear ratio, id always heard of people upgrading to lower gear ratios so kinda just did it blind. feels more powerful, but when i drove it on the freeway, get crazy vibration, i want that to stop.

 

Thanks dude. Im hoping for a low 13. They are hooking great on the street right now so im thinking they will be great on the track. I got a whole week to pratice on the street so I should be good when I get to the track. I did a 2.066 before with the 3.27's so I dont know what I will get now.

How many miles did you get out of your Nitto's?

 

still got em, have about 100 passes on them and you've seen the burnouts in the vids too poor tires their practically bald in the centers now (word of advice - run the tires at around 24 psi on the street, no higher or they'll look like mine from runnin em at 28). Prolly got around 7k miles on em. Gonna get another 1k before their toast. Woulda lasted 10k+ were it not for that 1 burnout on that vid

 

Yeah, definitely don't drive your car until you get that fixed. That could be your gears getting ready to explode or another problem with your rear. Should have went 4.10's and not tree sebenty tree...but whatever.

 

might be the driveshaft

 

True, but driveshaft issues are usually felt coming off idle, silenced at low speeds and really nasty on the highway. Either way man, get the car on a lift and have the obvious checked, if the driveshaft, LCA's, shocks & springs look alright, it might be time to pull out those gears and maybe pull the rear. Did you happen to have those 3.73 gears in your other rear when it grenaded...
